Output channels can be configured or "grouped" to create a single output with higher current and
power capability. Almost all instrument functionality is supported by grouped channels, including
voltage and current programming, measurements, status, step and list transients. The following
conditions apply:
Up to four output channels can be grouped per mainframe.
l
Output channels that are grouped must also be connected in parallel as described under
l
Connections.
Grouped channels do not have to be adjacent, but they must have identical model numbers and
l
options installed.
The maximum output current is the sum of the maximum of each channel in the group.
l
Low current measurement ranges should not be used with grouped channels, otherwise a meas-
l
urement overload error will occur. Low current output ranges, however, can be used.
Over-current protection delay has a slightly slower response time (~10 ms) and slightly less res-
l
olution than an ungrouped channel.
When output channels have been grouped, they are addressed using the channel number of the
l
lowest channel in the group.
Power limiting should not be used when Keysight N673xB, N674xB, and N677xA power modules
l
are grouped. Refer to
Front Panel Menu Reference
Select System\Groups.
In the matrix that appears, select the channels you want
to group. Each row defines a separate group.
To return grouped channels back to an ungrouped state, first remove the parallel connections
between channels and proceed as follows:
Front Panel Menu Reference
Select System\Groups.
In the matrix, place each output channel in its own
separate group.
Reboot the unit for the changes to take effect.

To configure a group of channels:
SYST:GRO:DEF (@2,3,4)
This groups channels 2 through 4. To address the
group, use channel 2.
