Universal Commands

DCL

The DCL (Device Clear) command causes all HP-IB instruments, or
addressed instruments, to assume a cleared condition. The definition of
device clear is unique for each instrument. For the power meter:
For further information refer to "Using Device Clear to Halt
Measurements", on page 1-92.

GET

The GET (Group Execute Trigger) command triggers all channels that are
in the "wait-for-trigger" state.
Using the *DDT command may change the function of the GET command.
Error Message
If TRIGger:SOURce is not set to BUS then error -211, "Trigger ignored"
occurs.
If the power meter is not in the "wait-for-trigger" state then error -211,
"Trigger ignored" occurs.

GTL

The GTL (Go To Local) command is the complement to remote. It causes
the power meter to return to local control with a fully enabled front panel.
When reverting to local mode the power meter triggering is set to free run.
