Abstract
Monitoring a demodulator includes repeating the following for each demodulating module of one or more demodulating modules of a demodulator: receiving a first signal and a second signal from a demodulating module; introducing a relative delay between the first signal and the second signal; and asynchronously sampling the first signal and the second signal to yield samples. Image data representing the samples associated with the demodulating modules is generated. The image data indicates one or more mismatches of the demodulator.
