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 page 47).
3 Connect channel 6 DAC output to the DMM input. Set the DMM to
measure DC volts.
4 The calibration procedure makes two adjustments per channel. 
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.
5 Repeat steps 3 and 4 for channel 7.
