Overview
This code demonstrates how to perform in-situ calibration with supported SC Express modules and their connected rackmount accessory. Check the hardware requirements listed below for configurations that support in-situ calibration.
Description
The example makes a call to the rackmount to switch a user-provided precision DC signal wired into the rackmounts calibration bus to and from the module’s ADCs. Doing so allows users to calibrate the ADCs with a precision signal at any desired test point to create a custom scale for the duration of a test.
Requirements
Software
Hardware
NI PXIe-4339 with the NI RM-4339 accessory
Steps to Implement or Execute Code
The example contains a dummy VI that prompts the user to set the calibration source to a certain voltage. The user can either follow the prompts and change the source manually or replace the dummy VI with a driver call to the calibration source to automate the procedure.
