Universal Commands

DCL
The DCL (Device Clear) command causes all GPIB instruments, or
addressed instruments, to assume a cleared condition. The definition of
device clear is unique for each instrument. For the power meter:
• All pending operations are halted, that is, *OPC? and *WAI.
• The parser (the software that interprets the programming codes) is
reset and now expects to receive the first character of a programming
code.
• The output buffer is cleared.
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.
LLO
The LLO (Local Lock Out) command can be used to disable the front panel
local key. With this key disabled, only the controller (or a hard reset by the
line power switch) can restore local control.
