*CAL?
Query
DESCRIPTION The *CAL? query causes the oscilloscope to perform an internal
self-calibration and generates a response that indicates whether or
not your oscilloscope completed the calibration without error. This
internal calibration sequence is the same as that which occurs at
power-up. At the end of the calibration, after the response has
indicated how the calibration terminated, the oscilloscope returns to
the state it was in just prior to the calibration cycle. This includes the
AUTO_CALIBRATE status, which is not affected by the use of
*CAL?. That is, *CAL? may be used whether AUTO_CALIBRATE
has been set on or off.
