3 Calibration Procedures
Analog Output Adjustment
Install the 34952A module in the mainframe and allow a 1 hour warm-up before
performing these procedures.
This adjustment procedure sets a zero adjustment and a gain adjustment
constant for each DAC output. You must perform all the adjustments on one
analog output channel before adjusting the other analog output channel.
1 Install the module(s) in the instrument.
2 Unsecure the instrument for calibration (see
3 Connect channel 6 DAC output to the DMM input. Set the DMM to measure
4 The calibration procedure makes two adjustments per channel.
5 Repeat steps 3 and 4 for channel 7.

DC volts.
After sending the first command, measure the module output. Send the
measured value to the module and advance to the next point.
This procedure is summarized as follows:
a Send the following command to begin the procedure.
CALibration:BEGin:VOLTage 1,(@<channel>)
b Measure the module output.
c Send the measured value to the module with the following command:
CALibration:POINt? <value>
d The command returns a "+1" to indicate it is ready for the next point.
e Measure the module output.
f Send the measured value to the module with the following command:
CALibration:POINt? <value>
g The command returns a "+0" to indicate the calibration on the channel is
completed.
