Voltage Adjustment
Chapter 5
Voltage output adjustment uses two of the CALibration subsystem queries.
CALibrationn:CONFigure:VOLTage?
CALibrationn:VALue:VOLTage? <value>
The general procedure for channel voltage adjustment is:
Make the connections shown in figure 5-3 or 5-4.
1.
Send the CAL n :CONF:VOLT? query to the module and read the
2.
response until a 1 is returned (typically the first query response).
Read the voltage output on the DMM.
3.
Send the DMM value read with the CAL n :VAL:VOLT? value
4.
query.
Enter the query response.
5.
Repeat steps 3, 4, and 5 until the CAL n :VAL:VOLT? value query
6.
returns a 0.
Repeat steps 1 through 6 for each channel.
7.
The first query, CAL n :CONF:VOLT?, sets the channel to the calibration
mode and returns a 1 when the channel is ready for calibration. When a 1 is
returned, the channel output voltage is set to the first adjustment point.
Read the output voltage on the DMM and return the value obtained using
the CAL n :VAL:VOLT? value query. This query returns an integer
indicating the calibration state of the channel. Any non-zero return from this
query indicates additional values are needed.
Each channel will require multiple iterations of the
CAL n :VAL:VOLT? value query. A minimum of 9 queries, to a
maximum of 50 queries, will be required at each channel. During the
process, the output voltage will range from +16 V to -16 V and the last
values output will be at or near 0 volts.
