Title:
DETECTION APPARATUS AND METHOD FOR ATE TEST CHANNEL
Document Type and Number:
WIPO Patent Application WO/2023/115627
Kind Code:
A1
Abstract:
A detection method for an ATE test channel, which method is used for determining whether the calibration of a sending direction of a test channel is in effect. The method comprises the following steps: S01, connecting at least two test channels to an oscilloscope by means of wires of equal length; S02, editing, on an ATE platform, the same test program for each test channel, and the test program controlling each test channel to send at least one waveform; S03, running the test program, and displaying, on the oscilloscope, the waveform of each test channel; and S04, determining, by means of the waveform alignment situation of each test channel, whether the calibration of a sending direction of each test channel is in effect. During the process of determining whether the calibration of a sending direction of a test channel is in effect, the dependence on a dedicated device is reduced, thereby reducing detection costs.
