Abstract

PURPOSE:To make the observation of a steep frequency response easy, by a narrow band sweep for a desired frequency part and its vicinity within a frequency sweep band of a sweep signal through slow sweep speed. CONSTITUTION:A narrow band sweep controller 16 is connected between a triangle wave generator 10 generating a triangle signal and a sweep control circuit 12. A sweep control circuit 12 receiving a triangle wave signal generated from said device 16 through a part of modification incorporates a DC voltage source, and a DC voltage from said voltage source and a partly modified triangle wave signal are respectively summed with suitable magnitude to generate a sweep control signal. A sweep signal generator 14 consists of a voltage controlled oscillator and generates a frequency sweep signal having a frequency in response to a voltage value of the received sweep control signal. Thus, a part with greater slope of the sweep control signal has a large frequency sweep speed as broad band sweep and a part with small slope is slow in the frequency sweep speed as narrow band sweep.
