ABSTRACT:
A frequency characteristic measuring apparatus measures a device under test in which the frequency of an input signal and the frequency of an output signal differ from each other, simplifying the configuration of a tracking generator and peripheral circuits associated with the tracking generator, and simultaneously measuring the characteristics of the input signal and the output signal of the device under test. A spectrum analyzer has mixers, local oscillators and IF sections as first and second measuring units for measuring frequency characteristics of two input signals by performing frequency sweep in correspondence with a first or second frequency range, a mixer and an oscillator as a tracking generator section which operates by being linked to the frequency sweep operation in the first measuring unit, and a section which generates a trigger signal designating measurement start timing.
