Abstract:
1. A frequency characteristic measuring apparatus comprising: a first measuring unit which measures a frequency characteristic of a first input signal by performing frequency sweep corresponding to a first frequency range; a second measuring unit which measures a frequency characteristic of a second input signal by performing frequency sweep corresponding to a second frequency range; a tracking generator section which operates by being linked to the frequency sweep operation in the first measuring unit, and outputs an output signal having the same frequency as that of the first input signal as a frequency characteristic measurement target; and a trigger generating unit which generates a trigger signal designating measurement start timing in each of the first and second measuring units, wherein the output signal from the tracking generator section is input as the first input signal to the first measuring unit, and wherein the output signal from the tracking generator section is input to a device under test, and an output signal from the device under test is input as the second input signal to the second measuring unit.
