48 Digitizer Command Reference
•
There is no calibration DAC output for the 64 volt and 256 volt ranges. See
the CALibration:GAIN command for more information about the calibration
of these two ranges.
•
An error will occur if the voltage value specified is greater than that allowed
for the present range setting. You must set the desired range prior to setting
the calibration DAC voltage.
•
Executable when initiated: No
•
Coupled Command: No
•
Reset (*RST) Condition: 0.0 volts
:DAC:VOLTage?
CALibration:DAC:VOLTage? MIN | MAX queries the setting of the calibration
DAC (HP E1564A 4-Channel Digitizer only). The DAC voltage is output to the
calibration bus and accessible at the front panel D-connector only if the
CALibration:SOURce is set to INTernal. The MIN parameter returns the minimum
voltage available from the DAC and MAX returns the maximum voltage available
from the DAC.
:DATA?
CALibration:DATA? returns the calibration constants currently stored in
non-volatile calibration memory.
:GAIN
CALibration:GAIN[<channel>] [<readings>|
DEF
][,<rate>|
DEF
][,ON|1|OFF|0]
initiates a gain calibration on the channel specified. The ON parameter will cause
the 64V and 256V ranges to be indirectly calibrated from the 16V range gain
calibration. The ON/OFF parameter is ignored except for a gain calibration of the
16V range. The following steps must be completed prior to executing a gain
calibration:
•
Set the digitizer to the desired range and filter on the channel you want
to calibrate with the VOLTage[<channel>]:RANGe <range> and
INPut[<channel>]:FILTer:FREQ <freq> and :FILTer:STATe ON|OFF
commands.
•
Enable calibration with the CALibration:STATe ON command.
•
Specify the calibration source with the CALibration:SOURce command.
•
Specify a calibration value for the channel you are calibrating. The value must
be between 85% and 98% of either a positive full scale reading or negative full
scale reading. The ideal calibration value is 98% of positive or negative full
