SYSTem:ACALibration Subsystem
This subsystem is use to perform autocalibration. Autocalibration compensates for internal drifts caused by time
and temperature change. This can help to eliminate the errors to achieve a better performance. Following the
autocalibration, the instrument returns to the instrument state that existed before the autocalibration.
Only supported on DAQM907A multifunction module, DAQM909A Digitizer module and internal DMM.
Command Summary
SYSTem:ACALibration?
SYSTem:ACALibration:DATE?
SYSTem:ACALibration:INTerval
SYSTem:ACALibration:INTerval:MDAY
SYSTem:ACALibration:INTerval:TIME
SYSTem:ACALibration:INTerval:WDAY
SYSTem:ACALibration:TEMPerature?
SYSTem:ACALibration:TIME?
SYSTem:ACALibration? {<slot> | DMM | ALL}
Returns the autocalibration state in either a specified multifunction module slot, a specified digitizer module slot,
the internal DMM, or all.
Parameter Typical return
<slot> = {1|2|3}, any slot number with DAQM907A multifunction or DAQM909A digitizer module installed
DMM = Internal DMM
ALL = All three autocalibration state of Internal DMM, slot of DAQM907Amultifunction module and slot
of DAQM909A digitizer module.
+0 or +1
Returns the autocalibration state in slot 1:
SYST:ACAL? 1
Returns the autocalibration state in the internal DMM:
SYST:ACAL? DMM
Returns the autocalibration state in both slot and internal DMM:
SYST:ACAL? ALL
– SYSTem:ACALibration?ALL command is equivalent to *CAL?.
– If there is no any DAQM907Aand DAQM909A module installed, instrument will only perform the autocalibration
on the internal DMM.
