Programming DC Voltage
The AC6800B Series can output DC voltage. When the output is turned on, you cannot change the
output mode or voltage range. You must turn the output off first. You can set the voltage regardless of
whether the output is on or off.
The general procedure for specifying DC output is:
Step Description
1
Turn the output off (optional).
2
Select the DC voltage mode.
3
Select the DC voltage range (155 V, 310
1
V, or AUTO)
.
4
Specify the DC voltage limit to be slightly
larger than the voltage to be output.
5
Specify the DC voltage to be output.
6
Turn the output on.
1
The DC voltage range for the 155 V range is ±222.5 V, and for the 310 V range it is ±445.0 V.
DC Voltage Limit
The instrument allows you to limit the allowable values for the voltage offset. The following example
allows the
VOLTage:OFFSet
limit of DC mode is 0.0 V, so remember to change the limit if you need to output a negative DC voltage.
VOLTage:RANGe 310
VOLTage:OFFSet:LIMit:UPPer MAX
VOLTage:OFFSet:LIMit:LOWer MIN
The
*RST
default for VOLTage:OFFSet:LIMit:LOWer is to 0 for safety reasons.
