*OPC
Operation Complete Event Bit Command. This command causes Bit 0 of the Standard Event
Status Event register to be set when the electronic load has completed all pending operations. (See
*ESR? for the bit configuration of this register.) Pending operations are complete when:
Ϯ All
previous commands have been executed.
Ϯ Any
change in the input level caused by previous commands has been completed.
(Effects of slew time have been accounted for.)
Ϯ No pending trigger level operations are set for the single electronic load or for any
channel of the multiple electronic load.
*OPC does not prevent processing of subsequent commands but Bit 0 will not be set until all pending
operations are complete
