wallage Posted March 22, 2021 Report Posted March 22, 2021 I have a PXI setup with a PXIe-4081 DMM in it. I am trying to capture a current waveform, at 25kHz. For some reason the first 8 seconds of the data capture seem to float, after which the signal stabilizes. Does anyone know the cause, and solution for this problem? below is a snapshot of the data. The DMM is connected in series with a LED load, which is connected to a DUT. Quote
Gribo Posted March 30, 2021 Report Posted March 30, 2021 Try configuring the DMM to use a single range. If there is an auto range function active, it might explain the waveform. Can you post the circuit? Quote
