ABSTRACT:
A frequency domain characteristic of a system under test (SUT) is measured by using a digital signal corresponding to a swept frequency analog signal. In the case of a digital SUT, the digital signal is applied to the SUT, the output signal from the SUT is converted to analog form, and a measure of the peak-to-peak amplitude of the analog signal is derived. In the case of an analog SUT, the analog signal is converted to digital form, the analog signal is applied to the SUT, and a measure of the peak-to-peak amplitude of the output signal from the SUT is derived.
