NI PXI-5422 Calibration Procedure 4 ni.com
The output accuracy requirements of your application determine how often
you should externally calibrate the NI PXI-5422. NI recommends that you
perform a complete external calibration at least once every two years.
You can shorten this interval based on the accuracy demands of your
application. Refer to the External Calibration Options section for more
information.
Software and Documentation Requirements
This section describes the software and documentation required for both
self-calibration and external calibration.
Software
Calibrating the NI PXI-5422 requires installing NI-FGEN version 2.2 or
later on the calibration system. You can download NI-FGEN from the
Instrument Driver Network at
ni.com/idnet. NI-FGEN supports
programming the Self-Calibration Procedures and the External
Calibration Procedures in the LabVIEW, LabWindows
™
/CVI
™
, and C
application development environments (ADEs). When you install
NI-FGEN, you only need to install support for the ADE that you intend to
use.
NI-FGEN 2.2 or later includes all the functions and attributes necessary for
calibrating the NI PXI-5422. For LabWindows/CVI, the NI-FGEN
function panel (
niFgen.fp) provides help about the functions available.
LabVIEW support is in the
niFgen.llb file, and all calibration functions
appear in the function palette.
Calibration functions are C function calls or LabVIEW VIs in NI-FGEN.
In this document, the C function call is shown first, followed by the
corresponding LabVIEW VI, or NI-FGEN LabVIEW property node,
in parentheses. The C function calls are valid for any compiler capable of
