Noise on NI-9205 with cDAQ-9178

Noise on NI-9205 with cDAQ-9178

‎01-02-2026 02:08 AM - edited ‎01-02-2026 02:09 AM

I am using the NI-9205 (for voltage signals from UTM using BNC cable) and the NI-9235 (for strain signals) with the cDAQ-9178 chassis for materials testing.

The voltage signals  in differential mode without ground

I got significant noise during data acquisition, as shown in the image below.

Can i find recommended solutions to reduce or eliminate noise?

How are you connecting and how are you capturing the signal by configuring DAQmx?
