The following figure is an example of actual verification. In Figure A, the AUX OUT of the oscilloscope is connected to the test fixture through a coaxial cable, and the other end of the test fixture is connected to one channel of the oscilloscope through an SMA-PBNC adapter (connected to channel 3 in this example) , connect the probe to channel 1, and adjust the waveform on the screen to make an edge step waveform appear, as shown in Figure C, and save this waveform as a reference waveform. As shown in Figure B, the probe and accessories to be verified are measured on the test fixture. As shown in Figure D, three waveforms appear on the screen. The blue one is the reference waveform, the green one is the measured waveform affected by the probe, and the yellow one is the measured waveform. It is the waveform displayed by the probe. By testing the rise time parameters, overshoot parameters, etc., the performance of the probe and probe accessories can be confirmed.
