P5205 Probe Under-compensate Problem

Post by Tianxiang » May 30th, 2017, 11:33 am

Hi Folks,

I have a P5205 differential probe, but it is obviously under-compensate.

Does anyone know how to make it right?

The P5205 is a differential probe and is not like a standard “passive” voltage probe which has a low frequency compensation range. The signal you are seeing could be a result of the probe loading your signal source thus causing the front edge to roll up. Or the probe could be defective. You can download the User manual from Tek.com (search for 070947203) and refer to the Performance Verification section to verify the performance of your probe.
