摘 要：
A system, apparatus and method for performing differential return loss
measurements and other measurements as a function of frequency uses a digital storage oscilloscope (DSO) having
spectral analysis functions. A waveform generator generates a differential test signal in the form of a series of pulses where each pulse includes spectral components associated with each of a plurality of frequencies of interest. A test fixture presents the differential test
waveform to a load including at least one of a device under test (DUT), a short circuit, an open circuit and a balanced load. A signal acquisition device
differentially measures the test waveform during each of the load conditions. The signal acquisition device computes an error correction parameter using
measurements made during the short circuit, open circuit and balanced load
