FREQUENCY MODULATED (FM) CHIRP TESTING FOR AUTOMOTIVE RADARS USING STANDARD AUTOMATED TEST EQUIPMENT (ATE) DIGITAL PIN CHANNELS

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.

1. A method for characterizing a frequency modulated (FM) chirp signal generated by a device under test (DUT), the method comprising:
receiving a selection of a sample frequency and chirp duration for capturing the FM chirp signal; down converting the FM chirp signal; capturing the FM chirp signal using a digital pin electronics card to produce a captured FM chirp signal; 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.
