Issue Details

I would like to do differential measurement with my PXIe-5105 oscilloscope card, but I don't find any related hints in the manual of the product. Is there a possibility to conduct differential measurements with the PXIe-5105?


Yes, it is possible to measure voltage signals differentially with the PXIe-5105 oscilloscope card by applying the NI 5191 differential probe. Since the PXIe-5105 oscilloscope card has SMB connectors, and the NI 5191 active differential probe has BNC output, a BNC to SMB adapter will be necessary.
