:CALibration Subsystem
:CALibration[:ALL]?
This query causes an internal interpolator self-calibration .
• Numeric data transferred as ASCII bytes in <NR1> format.
• A value of zero indicates the calibration completed without error. A value of
one indicates the calibration completed with error.
Query only.
:CALibration:COUNt?
Queries the number of times the Counter has been calibrated.
By monitoring the calibration count, you can determine whether an unauthorized
calibration has been performed.
The following commands (as well as the front-panel invoked calibrations)
increment the count upon the completion of a successful calibration:
:DIAG:CAL:INP[1|2]:GAIN:AUTO ONCE
:DIAG:CAL:INP[1|2]:OFFS:AUTO ONCE
:DIAG:CAL:ROSC:AUTO ONCE
:DIAG:CAL:TINT:FINE[1|2|3|4]
:DIAG:CAL:TINT:QUICk
The :CAL:DATA command also increments the calibration count.
Numeric data transferred as ASCII bytes in <NR1> format.
• Query only.
• The calibration count is stored in non-volatile memory,
thus cycling power will not reset value.
• The calibration count is unaffected by power-on, save/recall,
and *RST.
• The calibration count increments up to a maximum of 32,767 after which it
wraps around to 1. (A value of 0 indicates no calibration has been performed
since the last reset of the non-volatile memory.)
