IN-SYNC DIGITAL WAVEFORM COMPARISON TO DETERMINE PASS/FAIL RESULTS OF A DEVICE UNDER TEST (DUT)
Publication number: 20240163623
Abstract: Embodiments described herein generally relate to analyzing a signal generated by a device under test (DUT). In particular, the signal generated by the DUT may be compared to a reference signal to determine pass/fail results for the DUT. For example, a method may include: storing, on a computing device, a reference signal from a reference device; receiving a test signal from a device under test (DUT); synchronizing the reference signal and the test signal based on a time-synchronization buffer of each signal; after the synchronization, comparing the test signal and the reference signal to determine a pass or fail result for the DUT; and generating a notification indicating the pass or fail result for the DUT.
