5 Calibration
Self-Calibration
The Keysight U2300A series USB data acquisition devices are factory-calibrated
before shipment. The on-board reference voltage is calibrated and measured to
ensure measurement accuracy. The device includes a self-calibration function to
ensure accuracy of the measurement made under different environment usage.
For self-calibration, executing the calibration command will initiate a voltage
adjustment in sequence for the specified DAC channel. This sequence sets a zero
and gain adjustment constant for each DAC output.
Self-calibration can be initiated using the following SCPI command:
The functions of the DAQ will be halted until the self-calibration process is
completed. You can query the status of calibration through the following SCPI
command:
– Unplug all cables that are connected to the DAQ device before
