*RST — reset
When the *RST command is sent, the power supply performs the following operations:
1. Returns the instrument to the RST default conditions (see "Default" column of SCPI
tables).
2. Cancels all pending commands.
3. Cancels response to any previously received *OPC and *OPC? commands.
*TRG[1] — trigger
power supply
*TRG2 — trigger
power supply
Use the *TRG command to trigger a single reading for the function presently selected. If the
average count is >1, then the single reading will be the average reading.
*TST? — self-test query
Use this query command to perform a checksum test on ROM. The command places the
coded result (0 or 1) in the output queue. When the power supply is addressed to talk, the coded
result is sent from the output queue to the computer.
A returned value of zero (0) indicates that the test passed, and a value of one (1) indicates that
the test failed.
*WAI — wait-to-continue
pleted
Effectively, the *WAI command is a no-op (no operation) for the power supply and therefore,
does not need to be used.
Two types of device commands exist:
• Sequential commands — A command whose operations are allowed to finish before the
next command is executed.
• Overlapped commands — A command that allows the execution of subsequent
commands while device operations of the overlapped command are still in progress.
The *WAI command is used to suspend the execution of subsequent commands until the
device operations of all previous overlapped commands are finished. The *WAI command is not
needed for sequential commands.
