[0002] When doing new product introduction and new design performance certification testing, it is necessary to use an oscilloscope to test the corresponding test points on the circuit board according to the test task book. Obtain the signal waveform when the board under test is working, and judge the signal quality based on the waveform and its related parameters.

[0003] Usually, the circuit board is fixed on the operating table, and a series of tests are performed on the board under test by manually operating the oscilloscope probe and ground wire. The entire board under test needs to be tested at thousands of test points, and the relevant test results must be recorded.
