AUTO_CALIBRATE, ACAL
Command/Query
DESCRIPTION
The AUTO_CALIBRATE command is used to enable or disable
the automatic calibration of your X-Stream 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 will
perform 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.
