摘要
A method for characterizing a FM chirp signal generated by a device under test (DUT) is disclosed. The method comprises receiving a selection of a sample frequency and chirp duration for capturing the FM chirp signal. The method also comprises down converting the FM chirp signal and capturing the FM chirp signal using a digital pin electronics card. The method comprises obtaining a plurality of period measurements from the captured FM chirp signal using a timing measurement unit (TMU) of an automated test equipment (ATE) and converting each of the plurality of period measurements into corresponding frequency values.
