MISCELLANEOUS Commands and Queries
AUTO_CALIBRATE, ACAL
Description
The AUTO_CALIBRATE command is used to enable or disable the automatic calibration of your
XStreamDSO oscilloscope. At power-up, auto-calibration is turned ON, i.e. all input channels are
periodically calibrated for the current input amplifier and timebase settings, whether the instrument has
been adjusted or not.
Whenever you adjust a gain or offset, however, the instrument performs a calibration. This action occurs
whatever the current state of ACAL, and it does not change the state of ACAL.
Automatic calibration can be disabled by means of the command ACAL OFF. But whenever convenient,
you can issue a *CAL? query to fully calibrate the oscilloscope. When the oscilloscope is returned to local
control, periodic calibrations are resumed if the last ACAL value was ON. That is, the command *CAL? has
no effect on the ACAL status.
The response to the AUTO_CALIBRATE? query indicates whether auto-calibration is enabled or disabled.
