Device 6,7 and the 3rd signal generator 8 of secondary signal generator connect the input port of the power splitter.In the present embodiment, institute
Power splitter is stated as four input ports, the power splitter of an output port, correspondingly, the quantity of signal generator is then 3, other
In embodiment, the power splitter can be the power splitter of other specifications, and the signal generator can also be other quantity.
The signal generator, which can simulate, to be sent including WIFI signal, white gaussian filtering, carrier wave, the signal of 2G, 3G
Signal, 4G the various electromagnetic signals such as signal one or more, to test work of the determinand under various interference signals
State.
Same frequency anti-interference test system provided herein at work, first makes to determinand matching unit to match to treat
The normal working condition of object is surveyed, then by adjusting the first and second attenuators, determinand is made to be in what can just be worked normally
Critical condition, opening signal generator, is passed through interference signal afterwards, is filled on determinand, to verify the anti-interference of determinand
Performance.
In conclusion same frequency anti-interference test system provided herein is able to verify that product under complex electromagnetic environment
Antijamming capability, so as to provide the quality of product, enhance the antijamming capability of product.
Foregoing description is only the description to the utility model preferred embodiment, not to any limit of the scope of the utility model
Calmly, any change, the modification that the those of ordinary skill in the utility model field does according to the disclosure above content, belonging to right will
Seek the protection domain of book.
