Temperature drift and other environmental changes can lead to performance degradation for several VST specifications. Self-calibration adjusts the instrument for variations in the environment using an onboard high-precision calibration tone.

Perform self-calibration to compensate and optimize the performance of the PXIe-5842 for a given ambient temperature and operating environment.

Note The onboard temperature may fluctuate despite consistent ambient operating temperature. For optimum performance, NI recommends that you periodically verify onboard temperature, especially after changes to the device configuration, and perform self-calibration as necessary. Refer to the specifications or safety, environmental, and regulatory information document for your instrument for more information about operating temperature specifications.
Note NI recommends that no external signals are transmitted to the RF input port during the self-calibration.
