Could USB-6002, switching power supply, or another component cause oscillating measurements?

Could USB-6002, switching power supply, or another component cause oscillating measurements?

‎10-19-2020 10:14 AM

In LabVIEW, the signal from the load cell is noisy and oscillates even when it's not being loaded. My question is: Is there a possibility it could be due to the DAQ or power supply?

 

The set up: 

NI USB-6002 DAQ

Omega DMD 4059 amplifier

Omega LCGB-10K load cell 

DC Power Supply (https://www.automationdirect.com/adc/shopping/catalog/power_products_(electrical)/dc_power_supplies/...

 

Ideally, we would have the NI-9237 instead of the UAB-6002. Could the USB-6002 cause this problem, or is there a greater likelihood that it's the switching power supply/something else? ANY help would be greatly appreciated!
