|Test Equipment|||||Test Conditions|||||Device Setup||||
|Note The VirtualBench procedure supports verifying and adjusting each device function. To minimize connection and test time during verification and adjustment of the device, the Verify, Adjust, and Re-verify operations are grouped by device function. If you need to verify the performance of the entire device prior to adjusting, NI recommends that you perform Verify Only first, and then perform an Adjust operation after completing a full verification.|
The following tables list the test equipment required to calibrate the VB-8012.
