NI 5402/5406 Calibration Procedure
12. Close the instrument driver session, destroy the instrument driver
session and all of its properties, and release any memory resources
NI-FGEN uses by calling the niFgen Close VI.
13. If any of the errors are greater than the
calibration test limits
, perform
an
.
Verifying the Main Path Gain and Offset Accuracy
This test verifies the main path gain and offset accuracy of the
NI 5402/5406 into a high-impedance load. In this procedure you generate
a number of DC voltages and offsets, measure the voltage with a DMM,
and compare the results to the error limits.
1.
Connect the NI 5402/5406 CH 0 front panel connector to the DMM.
2.
Open an instrument driver session, initialize the device for operation,
and return a session handle that will be used to identify the device in
future NI-FGEN calls by calling the niFgen Initialize VI.
