National Instruments NI PXI-5422 Benutzerhandbuch

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 

 section for more 

information. 

This section describes the software and documentation required for both 
self-calibration and external calibration.

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 

 and the 

 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
