Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention generally relates to a waveform measuring device using a microcomputer. The present invention relates to a waveform measuring device capable of performing 10-gram troubleshooting, in which a measuring section can be controlled by a program.

(Prior Art) The waveform measuring device of the present invention allows a user to specify and change the functions of the measuring device in an interactive manner to carry out desired measurements, data processing, display, etc. In particular, we use the measurement result as a waveform, that is, what kind of value the observed value, which is the number between X, has over a certain range of the spread variable This is useful for a waveform measuring device that displays a screen in two dimensions (X-y).

By the way, such waveform measuring devices include, for example, oscilloscopes and spectrum analyzers, which measure the period, amplitude or spectrum size, spectrum frequency, etc. of the observed waveform to be measured. However, such measurements based on waveform observation have low accuracy and have disadvantages such as the inability to easily perform measurements that are not directly displayed on the display screen (for example, average values and instantaneous maximum values). Ta.

In recent years, in order to compensate for these shortcomings, various waveform measurement devices have been commercialized that allow the user to perform extended measurements by pressing specific keys, in addition to the normal measurement function that is performed by setting measurement parameters from the front panel of the waveform measurement device. has been done.

The method employed in such a waveform measuring device will be explained below.

The first method is shown in Japanese Patent Publication No. 63-201525, in which the manufacturer registers and defines several frequently used measurement functions internally in advance, and then assigns this function (that function) to multiple function keys. This method also includes a function to display the identification name of the user.

If there are more extended measurement functions than function keys, the extended measurement functions are registered in a tree shape corresponding to the function keys, and the functions of the function keys can be changed by operating the menu key. The user can use the registered extended measurements by operating the menu keys and function keys while looking at the menu and identification name on the display screen.

In the second method, the user operates the measurement keys on the waveform measurement device to perform the desired measurement, stores the measurement parameters at that time in the internal memory using the save key and numeric keys, and then uses the recall key and numeric keys to store them in the internal memory. By specifying the address (so to speak, a registered address in the memory), a desired measurement can be performed. Anritsu Technical's "Spectrum Analyzer MS7", published in March 1986, has such a save/recall function.
10CJ.

In this method, among the normal measurement functions of a waveform measurement device, measurement functions for specific conditions selected by the user can be registered and called up one after another as needed to perform measurements, but in a broad sense. It is considered an extended measurement and has the effect of omitting measurement operations.

The third method is Anritsu Technical's ``Personal Computer Built-in.10'' published in September 1986.
0 to 2G) Iz Network/Spectrum Analyzer MS620JJ and "Embedded Computer System Supporting High-Speed ATE: PTAJ". Procedures, processing of measurement data,
Measurements are performed by programming and storing displays, etc., and pressing an execution key.

Further, this method is mainly used in devices that perform automatic measurements, and measurement programs and measurement data can be saved and loaded using an external storage device.

The fourth method is the low
This is a method called ``dable Progr'ammingJ''. This is done by using an external computer to write a command string for settings according to the measurement procedure into the non-volatile memory inside the spectrum analyzer via the general-purpose interface bus GP IB (HP IB). By pressing the Hzl key (unit key) on the spectrum analyzer, measurements are performed according to the measurement procedure written in the non-volatile memory.

(Problems to be Solved by the Invention) However, the conventional waveform measurement device as described above has
There were drawbacks as described below.

The waveform measuring device using the first method can only perform extended measurements provided by the manufacturer in advance, and the user cannot change the measurement contents or add functions.

In the case of measuring instruments that use the second method, only a series of normal measurement operations are registered, and advanced processing operations such as processing and judgment on measurement data and subsequent branching or repeated execution are performed. I can't do it. Therefore, among the extended measurements desired by the user, only simple ones can be registered.

Also, the registered measurement procedure is simply stored in the internal memory and does not have a dedicated key with the name of the measurement procedure, so you can record it on memo paper, for example. The desired measurement procedure cannot be called up unless the

The waveform measuring device using the third method has an advantage in automation of measurement. However, with a waveform measurement device that allows measurement programs stored in internal memory to be executed using the execution key, if you want to execute different measurement programs one after another and make measurements, you can load the measurement program from an external storage device each time. Therefore, there was a problem in that it was not possible to immediately execute any of the plurality of measurement programs in any order.

rDown lowdable in the fourth method
In the case of ProgramningJ, it seems that the problem in part - above has been solved, but it has the inconvenience of requiring an external computer when creating a program, and the external computer can perform control commands + spectrum for rGPIB. Since it is necessary to create a program as a series of "setting commands to control the analyzer," the problem is that the scale of the program becomes large and it takes time to create it. Another drawback was that measurement menus could not be defined in response to function keys.

The purpose of the present invention can be summarized from a comprehensive standpoint, including the above-mentioned problems, to provide a highly functional automatic measuring device that has a configuration that can function independently on its own and that can be programmed by the user, and that has at least the following: The purpose of the present invention is to provide a waveform measurement device equipped with all of the above functions.

(e) An interrupt function is provided, and multiple measurement keys and function keys can be operated at the same level for the user. In other words, the measurement parameters set by the measurement program and the measurement keys are at the same level, so if you want to instantly change the measurement parameters, you can easily change them by operating the measurement keys.

(Means for Solving the Problems) In order to achieve the above object, a waveform measurement device of the present invention includes a measurement section, a control device for controlling the measurement section, a user program editing and creation device, and a display control section. and a program control section are housed in one housing, and the housing has an integrated structure in which a display, a plurality of function keys, and a plurality of measurement keys are provided on the front panel of the housing.
This is a waveform measurement device that allows dedicated internal communication and automatic measurement.

The display control section includes a measurement display control section, a function key display control section, and a program display control section, thereby making it possible to complement the integrated structure in terms of display function and making it easy for the user to use. .

The program control section includes a program memory, a data memory, and a variable memory corresponding to the plurality of function keys, as well as a function key input processing section and a program execution section.

The user program editing and creation device includes editing means for receiving input information from a keyboard in ASCII code, creating a program to be executed by a program execution unit, and writing the program into a program memory.

The program execution unit can control so that information is transmitted from the measurement key to the measurement control device or not.

In addition, the measuring section and the data memory are connected by a set of buses.

Here, the measurement section has a function to perform the desired measurement, the measurement key is for inputting the conditions for performing the desired measurement, and the measurement control section is used to input information from the pressed measurement key. Alternatively, the program execution section has a function of causing the measurement section, data memory, and display control section to operate in accordance with a command issued by interpreting information in the program memory.

(Example) Here, an example in which a replaceable memory card 54 is not used in the user program editing and creation device 5 to be described later will be described as a first example, and an example in which the memory card 54 is used will be described as a second example.

[First example] FIG. 1 shows the configuration of an embodiment of the present invention.

In FIG. 1, the measuring section l converts the frequency of the input signal,
It amplifies and detects the intermediate frequency, performs rough signal processing such as A/D conversion, and detects the level relative to the frequency of the input signal.

The control device 2 includes a measurement control section 21, a data processing section 22, and a control input processing section 23. All of these operate according to information from the program execution unit 42 when a measurement program input from the user program editing and creation device 5 is executed, and operate according to information from the measurement key 31 at other times.

The front panel 3 has a measurement key 31 and a function key Fl.
- Consists of F5 and display 32. The measurement key 31 is used to set measurement conditions such as a measurement center frequency, frequency span, reference level, and resolution bandwidth when measuring an input signal. The function keys Fl-F5 can be used by the user by creating a measurement program using the user program editing and creation device 5. In addition,
Function key Fl-F5. is arranged right next to the display 32, and as described later, the function keys Fl~
When the function name of F5 is displayed on the display 32, it can be recognized accordingly.

The display devices 32 are controlled according to their respective purposes.

The user program editing/creating device@5 basically consists of a keyboard 519, a user output interface 52, and an editing means 53. The keyboard 51 consists of a series of keys such as numeric keys, character keys, symbol keys, and command keys for editing.
Mainly used by program editors to input control commands to control each device in the equipment, editing commands to create a measurement program based on the control commands, and execution commands to execute the measurement program. be.

In this example, each of these commands is input from the keyboard 51 in a language similar to a basic language, and is output in ASCII code. Therefore, instead of the keyboard 51, these commands may be input from any other input device as long as they can be input to the human output interface 52 in ASCII code.

The editing means 53 receives the coded control commands and editing commands interfaced by the human output interface 52, creates a measurement program based on the control commands, and writes it into the program memory 412. On the other hand, the measurement program is sent to the program display control section 62 to display the measurement program on the display 32. The editing means 53 is designed to allow the editor to complete the program while viewing it. Further, when the editing means 53 receives an execution command from the keyboard 51, it instructs the program execution section 42 to interpret and execute the measurement program.

The following information is required when the user edits and creates the ν determination program. In other words, the control commands for controlling each device in the equipment include a measurement control command for controlling each device in the measuring section l, a data processing command for processing the measurement results into desired data,
There are measurement display commands for displaying measurement results or processed data in a desired form, function key information related to function keys F1 to F5, and key display control commands for displaying function key information.

Note that some of these control commands are stored in advance in the subroutine memory 44 as system subroutines so that they can be read and used by the measurement program.

The measurement program created by the editing means 53 is written into the program memory 412. The variable memory 413 has variables corresponding to the function keys F1 to F5, receives setting information from the set function keys Fl to F5 from the function key input processing unit 43, and converts this setting information into the values of the variables. be memorized as .

The program execution unit 42 reads the measurement program and the subroutines and variable values written in the measurement program from the program memory 412, subroutine memory 44, and variable memory 413, interprets the instructions on the measurement program, and controls the contents. Send to device 2. Further, the program execution unit 42 controls the control input processing unit 23 to determine whether the control device 2 accepts information from the measurement key 31 or not.

When the measurement program is executed, the key display control section 63 receives a key display control command for displaying function key information among the contents of the measurement program, and causes the display 32 to display the function key information. Based on the displayed information, select the desired function key Fl-F5.
When set, a measurement control command in the content of the measurement program is sent to the measurement control section 21, a data processing command is sent to the data processing section 22, and a measurement display command is sent to the measurement display control section 61 for execution. The data processing section 22 is connected to the measurement section 1 and the data memory 411 via a dedicated bus in order to process measurement data at high speed.

In the above configuration, the memory device 41 is a data memory 41
1, a program memory 412 and a variable memory 413. Furthermore, the program control section 4 includes a memory device 41, a program execution section 42, and a function key input processing section 4.
3 and a subroutine memory 44.

Furthermore, the hardware configuration of the following includes a CPU.

The control device 2, the program execution section 42, the function key input processing section 43, the display control section 6, and the user program editing and creation device 5 which constitute the program control section 4. Note that the CPU is also used in each component. .

Next, the structure of this invention will be explained.

In this invention, each configuration in FIG.
As shown in Figure 2, the main feature is that all the parts are housed in one housing song. Note that the keyboard 514 C is separated for convenience, and can also be integrated into the housing.

In particular, in addition to general measurement means such as the measurement section 1, measurement control control section 2L, measurement control display section 61, and display 32,
By integrating function keys Fl-F5, user program editing and creation device 5, program control unit 4, etc., users can easily create measurement programs that can be expanded freely, and function keys F1-F5
It has the feature that you can execute operations with one touch by pressing .

Furthermore, the user program editing and creation device 5 and the program control unit 4 are computers equipped with dedicated subroutines that can be used by the user, and are also controllers.

A structure in which such functions are integrated as a waveform measuring device is very convenient for users to carry out various measurements on a dedicated basis.

The specific operation of this embodiment will be explained below.

■For normal measurement without using a measurement program In this case, the measurement device 2 controls the measurement unit 1 to perform measurement according to the deviation conditions set with the measurement key 31, processes the measurement data, and controls the measurement display. It is displayed on the display 32 via the section.

(2) When an operator creates a desired measurement program and executes the measurement program to perform measurement A specific example will be described below based on an example of an actual measurement program.

A) Creation of a measurement program Restore the main editing commands, execution commands, dedicated subroutines, and statements necessary for creating a measurement program in Table 1 (Table 1 also includes those for the second embodiment). include). The control instructions include those shown in Table 2, and these control instructions are programmed using the above statements. Further, the subroutine is also a type of control command.

FIG. 3 shows, as an example, the general flow of a measurement program in which a plurality of measurement items are assigned to function keys Fl to F5.

The line numbers and instructions in Tables 1, 2, and 3 are the line numbers and the like in the detailed measurement program shown in the tables (a) to (f) in FIG. 6. Hereinafter, the program creation procedure will be explained mainly based on FIG.

b) If you do not want to accept the setting command from the panel measurement key 31 as an interrupt while executing the measurement program created by the initial setting user program editing and creation device 5, write the panel lock command (1460CALL PNLL). If you want to add a receiver, use the panel lock release command (CALL P
Write NLtJ). In either case, a system subroutine (instruction written with "rCALL name") is prepared in the subroutine memory 44, so the instruction can be written in a predetermined format.

A command for initially turning on the measurement unit 1 and the display 32 is input. A command for initialization (PUT "I old") and a system subroutine related to display are prepared in advance, so it is sufficient to write them.

口) Definition and display of function keys F1 to F5 A system subroutine (CALL DEF (variable number, 'name')) is prepared for this purpose.
Write the variable number and measurement item name corresponding to F5 in a predetermined format.

In this example, the function key Fl is "■HF"
(VHFHF-star gain measurement), F2 Ni”B
S-IF” (BS tuner IF band booster gain measurement) and F3 “MIXER” (mixer loss measurement)
is assigned.

c) Write an initial setting command to set the system variables EXI to EX5 corresponding to the function keys F1 to F5 to the value "0".

2) Write a command to search which function keys Fl-F5 on the panel are selectively set when executed.

e) Write an instruction to select a measurement routine corresponding to the measurement item selected and set using the function keys F1 to F5.

Note that when both of the function keys F1 to F5, for example function keys F1 and F2, are pressed at the same time, priority is given to the one with the smaller variable.
It is preferable to give priority to the key and select the measurement routine corresponding to it.

f) Create a measurement routine according to the measurement item.

g) When executed, write a command to return to the state of c) so that it waits for settings using function keys F1 to F5 again after executing the measurement routine (normally,
RETURN command or GOTO command).

The writing of the measurement program in steps A) to G) above is performed using the keyboard 51, and the written measurement program is sequentially transferred to the program memory 41 by the collecting means 53.
2, it is simultaneously displayed on the display 32 via the key display control section 63.

B) Execution of Measurement Program (Measurement) When execution (RUN) is instructed from the keyboard 51, the program execution unit 42 interprets the contents of the measurement program written in the program memory 412 and controls each component. The operation will be explained below based on the general flow shown in FIG.

b) Since the program memory 412 contains the panel lock command, the initial setting program execution section 42 instructs the control input processing section 23 to reject the information from the measurement key 31 and to follow only the information from the program execution section 42. If there is a panel lock release command, it is instructed to follow both the information from the measurement key 31 and the command from the program execution unit 42.

Next, the program execution section 42 reads a command to initialize the measurement section 1 and the display 32 from the program memory 412, and sends the instruction to the measurement section Jgp section 21 via the control input processing section 23.
and sends a control command to the measurement control display section 61 to control the measurement section 1.
and initializes the display 32. In this case, the control command for initialization ("'1 old") is in the subroutine memory 4.
4 is prepared in advance. Specifically, the control command is
For example, measurement center frequency 1100MHz, frequency span 2
200MHz, reference level OdBm, etc. Note that in the subsequent measurement program, for example, unless a new control command is set in the measurement routine, the measurement unit 1 and the display 32 continue to operate under the conditions according to the previous control command.

Next, the program execution unit 42 reads the subroutine for the definition from the subroutine memory 44 in response to the definition command of the function keys F1 to F5 of the measurement program, and executes the measurement with the variables of the function keys F1 to F5 specified in the measurement program. Define the item name. Furthermore, the program execution unit 42 instructs the key display control unit 63 to display the name of the measurement item corresponding to the function keys Fl-F5 provided immediately on the display screen of the display 32. (In other words, the function name is given to the function keys Fl'-F5.) FIG. 4 shows an example in which the names of the function keys F1 to F5 are displayed.

c) Next, the program execution unit 42 sets the system variables EXI to EX5 in the variable memory 413 to the value "0".

2) The program execution unit 42 searches whether or not the value of the system variables EXI-EX5 in the variable memory 413 is set to "1" until it is set. That is, the program execution unit 42 waits for information from the function keys Fl to F5.

In this state, the operator looks at the function names of function keys 1 to F50 displayed on the display screen of the display unit 32, selects and presses the desired function key F2 (for example, in Fig. 4, the second function key from the top key). Next, the function key input processing unit 43 inputs the variable memory 4
Among the 13 variables, the value of the variable (EX2) corresponding to the pressed function key F2 is set to "1".

e) The program execution unit 42 detects which variable has the value "1" and jumps to the corresponding measurement routine (instruction starting from line number 33oO) in the program memory 412.

f) Send a control command to the control device 2 to execute the measurement according to the command written in the measurement routine.

g) After the program execution unit 42 finishes the measurement corresponding to the function key F2 that was pressed first, it waits again in the state of c) until the next function key is set.

h) The operations after the next function key is set are the same as in 2) to 4) above.

Here, the main operations in the reset routine (instructions starting from line number 3300) will be picked up and explained from the detailed measurement program shown in FIGS. 6(a) to 6(f).

a) GOSUB command at line number 3370 In other words, line numbers 3520 to 3850 are settings for parameters to be used in subsequent line numbers.

Line number 3570 FREQ=lE9 and 35805PA
N=IE9 is for setting the measurement center frequency and frequency span, respectively.

b) GO5LJB command line number 6 at line number 3380
040 PUT “AMB O” is data memory 411
This command is a control command for the data processing unit 22 to stop calculations in the A channel memory and B channel memory included therein.

The WRITE commands in line numbers 6050 and 6060 use the parameters set in line numbers 3570 and 3580 to set the center frequency to 1000 MHz and the frequency span to 10.
This is a command to the measurement control unit 21 to set the value to 0100O.

C) Setting of a character string used to display on the display 32 the line number after the GO5UB command in line number 3390.

d) GO5UB command line number 62 in line number 3410
The CALL DCH command from 20 to 6240 is a subroutine command for displaying the character string in the GO5UB command at line number 3390, and is a subroutine command for displaying the character string in the GO5UB command at line number 3390.
This is a command for 1. This is the display of the next operation menu associated with the redefinition of the next function key.

CALL DEF in lines 6250 to 6290
This command is used to redefine and use the function keys in this measurement routine.

Here, if the function key Fl is pressed, it is a command to write to the B channel memory of the data memory 411, and a command to prohibit reading. Line number 642
0 PUT "S%IIP" is a single sweep instruction and is a command to the measurement control unit 21.

e) GO5UB command line number 65 in line number 3430
The CALL command from 90 to 6630 is a command to re-define and display a function key, and a command to display a previously set character string. In other words, the next operation menu is displayed.

Here, if you set the function key F1fejSt,
At line number 6730, a memory conversion command called CALL C0NV is issued to the data processing unit 22.

f) GOSUB command in line number 3450 This is a standard line drawing command using a subroutine command related to display, and is a command to the measurement display control unit 61.

g) GO5UB command line number 68 in line number 3470
00 PUT "ASR" issues a write command to the data memory 411, line number 6820 PUT"TRG
A command to sweep with a free trigger condition (in other words, the initially set sweep condition) is sent to the measurement control unit 21 using the O parameter, and the data written in the data memory 411 is displayed at line number 6830 CALL CRN (6). The information is sent to the joint stock 8 false pretense control unit 6].

h) Line numbers 3480 to 3500 set (clear) system variables EXI to EX5 corresponding to function keys F1 to F5 to the value rOJ.

i) Line number 3510 (7) RETURN instruction and line number 1270 (7) G.

Return to initial state with TO command.

As explained above, it has the following functional characteristics.

・Since measurement functions and dedicated computer functions are integrated, dedicated subroutines and variables can be built-in. Therefore, complex measurement programs can be easily edited and created.

- The user can edit and create a desired measurement program using the variables and subroutines corresponding to the function keys Fl-F5, and the execution can be performed using the function keys 1-F50 function names (this display also This can be done with one-touch operation by looking at the steps (performed in the above subroutine). By defining variables and subroutines each time in the measurement program, a tree-like measurement program can be constructed and executed.

・When editing and creating a measurement program, the user can enter the panel lock release command at an appropriate location in the measurement program.
The measurement keys 31 on the front panel 3 can be operated at the same level as commands in the measurement program.

This is convenient when, for example, it is necessary to slightly change the measurement conditions during execution of the measurement program due to conditions such as the signal under test. Because, when interrupts are not possible,
Even the slightest change requires correction and editing of the measurement program.

[Second Embodiment] In this embodiment, a replaceable memory card 54 can be used in the user program editing and creation device 5 described above, so that the user can edit, create and execute a measurement program with higher expandability. There is something special about what you did.

The configuration of such a user program editing and creation device 7 is shown in FIG. In this embodiment, the basic elements remain the same except that the user program collection creation device 5 is replaced by the user program editing and creation device 7 in FIG.

1 in Figure 5. As the memory card 54, a magnetic storage card, an optical card, etc. can be used for IC memory. The card processing section 55 drives the memory card 54 and writes and reads data in accordance with instructions from the editing means 53.

In addition to the first embodiment, the file commands and memory card subroutine commands shown in Table 1 can be used as information that can be input from the keyboard 51. Accordingly,
The functions of the subroutine memory 44 and the program execution unit 42 should be increased.

Characteristic functions when using the memory card 54 will be explained.

■When creating a measurement program, prepare a basic measurement routine in advance on the memory card 54, for example, the measurement routine at step (f) in FIG. Setting information (variable values) assigned to keys Fl to F5 and from function keys F1 to F5
All you have to do is write an instruction that accepts the command and branches to each measurement routine. In other words, it has the feature that the measurement function can be easily expanded on the user side.

■ Execution of measurement program (measurement) When editing and creating a measurement program, by writing memory card subroutine commands into the measurement program, the commands of the measurement program can be directly executed on the memory card 54.
The memory contents (measured data) can be read out from or written to. Therefore, data collection is easy.

For example, in FIG. 6, the program execution unit 42 uses the command line number 6930 CALL 0PNO "XBSIF" to prepare for writing to a file named XBSIF in the memory card 54.
7) Collect measurement data using the FOR-NRXT process and write the data to a file in the memory card 54 using the CALL DASV command in line number 6970.

(Effects of the Invention) Since the present invention has the following characteristic structures and functions, it has effects corresponding to each and a comprehensive effect.

(a) In addition to general measuring means such as a measurement section, a measurement control display section, a measurement control display section, and a display, it is integrally equipped with a function key, a user program editing and creation device, a program bullet control section, etc. Therefore, there is an advantage that the user can freely expand various measurement programs and use them exclusively.

(b) Since a dedicated internal bus can be used, internal communication functions can be improved and high-speed control or data processing can be performed.

(c) Since the measurement function and dedicated computer function are integrated and dedicated subroutines and variables are included, complex measurement programs can be easily edited and created.

(d) In particular, the user can execute measurements with a one-touch operation by looking at the function names on the multiple edited measurement program display screens, selecting the desired measurement program, and pressing the corresponding function key.

(e) While the measurement program is running, the user can operate the measurement keys on the front panel at the same level as the commands in the measurement program.

This is useful when, for example, it is necessary to slightly change the measurement conditions during execution of a measurement program due to the conditions of the signal under test. Furthermore, when the measurement keys are mainly operated to perform measurements, the function keys can be used as part of the measurement keys. In this case, the measurement program defined in the function key has a measurement subroutine function when operating the measurement key.

(f) By configuring the system to use a memory card, editing and creating programs becomes very convenient.

(g) Since the memory card can be accessed from the measurement program, data collection is easy.
