Hardware

  • PXIe-4610

Issue Details

I am using the PXIe-4610 Amplifier Module but I am seeing some voltage spikes in the output signal as shown in the image below. 

Solution

Make sure that you are balancing the output of the PXI-4610 by adding resistance as shown in the image below. 
To make sure that everything is configured correctly, see the PXIe-4610 Getting Started Guide

Additional Information

Connecting a ground-referenced load or instrument to an NI PXIe-4610 output effectively short-circuits one output terminal to ground, which activates the short-circuit protection and causes the observed voltage spikes.
