Grouping the Outputs

		The ability to group outputs is only available on power system mainframes with
	NOTE
	NOTE	firmware revision B.00.00 and up.
		firmware revision B.00.00 and up.

		Once outputs have been connected in parallel, they can be configured
		or “grouped” to act as a single, higher-power channel. This applies
		when programming via the front panel or using SCPI commands.
		How to group output channels that have been connected in parallel is
		discussed in Chapter 4 under “System-Related Operations”.
