Allow test panels to provide voltage excitation for bridge/strain modules

Status: Implemented

Currently, DSA devices that use voltage excitation have no method to provide that excitation to a particular device within test panels. The only method to do this would be to create a task in Measurement and Automation Explorer which takes much more time that doing a simple test panels test. This should be a fairly simple addition to the test panels user interface. One could simply have a box to check if they require excitation, and a control to determine the voltage level to provide to the DUT. They currently have this for IEPE devices, and it makes sense that voltage excitation should be the same.

Hi Frank,

 

Have you seen the new multi-measurement test panel that was added for SC Express? On the PXIe-4330 and PXIe-4331 bridge/strain modules, the new test panel supports configuring the bridge type and excitation. On the PXIe-4353 thermocouple module, it supports switching between voltage and thermocouple measurements without creating a task in the DAQ Assistant.

In NI-DAQmx 9.3, CompactDAQ analog input should be getting a test panel upgrade.
