Specifications

·
The <ref_volts> parameter must be within 4% of the actual reference voltage
value as read after CAL:CONF:VOLT or an error 3042 ‘0x400: DSP-DAC
adjustment went to limit’ will be generated.
·
The <ref_volts> parameter may be specified in millivolts (mv).

CAL:VAL:VOLT <measured value> Send measured value to module
CALibration:ZERO?
CALibration:ZERO? corrects Analog to Digital converter offset for any drift since
the last *CAL? or CAL:ZERO? command was executed. The offset calibration
takes about five seconds and should be done as often as the control set up allows.
Comments
·
The CAL:ZERO? command only corrects for A/D offset drift (zero). Use the
*CAL? common command to perform on-line calibration of channels as well as
A/D offset. *CAL? performs gain and offset correction of the A/D and each
channel with an analog SCP installed (both input and output).
