Common Command Reference
The following reference discusses the HP E1313/E1413 IEEE-488.2 Common
Commands.
*CAL?
Calibration Command. The calibration command causes the Channel Calibration
function to be performed for every module channel. The Channel Calibration
function includes calibration of A/D Offset, and Gain and Offset for all 64 channels.
This calibration is accomplished using internal calibration references. The
*CAL?
command causes the module to calibrate A/D offset and gain, and all channel
offsets. This may take many minutes to complete. The actual time it will take your
HP E1313/E1413 to complete
*CAL?
depends on the mix of SCPs installed.
*CAL?
performs literally hundreds of measurements of the internal calibration sources for
each channel and must allow 17 time constants of settling wait each time a filtered
channel’s calibrations source value is changed. The
*CAL?
procedure is internally
very sophisticated and results in an extremely well calibrated module.
To perform Channel Calibration on multiple HP E1313/E1413s, use the
CALibration:SETup
command (see
CALibration:SETup
on page 179 for details).

The C-SCPI type returned is int16.
•
CALibration:STORe ADC
stores the calibration constants for
*CAL?
and
CALibration:SETup
into non-volatile memory.
•
Executing this command does not alter the module’s programmed state (function,
range, etc.), but it does clear bit 13 in the Questionable Data Group (see Table 5-4
on page 259).
•
This command will cause Error +3000, “ illegal while initiated” if trigger is initiated.
