2Introduction
Calibration
The PXI-2020/2022 includes a precision on-board reference with
very low temperature drift. This feature not only provides a stable
calibration source for auto-calibration but also maintains stable
acquisition accuracy over a wide temperature range. The auto-
mated calibration process can be done through software without
need for any manually adjustments. Once the calibration process
has completed, the calibration information will be stored in the on-
board EEPROM so that the values can be loaded and used as
needed by the board.
