Software Requirements
Calibrating the NI 5122/5124/5142 requires installing NI-SCOPE on the calibration system.
Refer to Table 1 for the hardware-specific version to use with your device. You can download
the NI-SCOPE
instrument driver from the Instrument Driver Network Web site at
ni.com/
idnet
. NI-SCOPE supports programming a Self-Calibration and an External Calibration in the
LabVIEW and C application development environments (ADEs). When you install NI- SCOPE,
you only need to install support for the ADE that you intend to use.
