*TRG
This command generates a trigger to any system that has BUS selected as its source (for example,
TRIG:SOUR BUS). The command has the same effect as the Group Execute Trigger (<GET>) command.
*TST?
This query causes the electronic load to do a self-test and report any errors.
0 indicates the electronic load has passed self-
test. Non-zero indicates an error code.
*WAI
This command instructs the electronic load not to process any further commands until all pending
operations are completed. Pending operations are complete when:
• All commands sent before *WAI have been executed. This includes overlapped commands.
Most commands are sequential and are completed before the next command is executed.
Overlapped commands are executed in parallel with other commands. Commands that affect
input voltage or state, relays, and trigger actions are overlapped with subsequent commands
sent to the electronic load. The *WAI command prevents subsequent commands from being
executed before any overlapped commands have been completed.
• All triggered actions are completed and the trigger system returns to the Idle state.
*WAI can be aborted only by sending the electronic load a GPIB DCL (Device Clear) command.
