IEEE-488 Command Reference
GPIB Universal Commands
DCL
The DCL (Device CLear) command causes all GPIB instruments to assume a
cleared condition. The definition of device clear is unique for each instrument. For
the N432A:
– All pending operations are halted, that are, *OPC? and *WAI.
– The parser (software that interprets the programming codes) is reset and now
– 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, or the N432A is not in the wait-for-trigger
state, error –211,"Trigger ignored" occurs.
GTL
The GTL (Go To Local) command is the complement to remote. It causes the
N432A to return to local control with a fully-enabled front panel. When reverting
to local mode, the N432A 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.
138
expects to receive the first character of a programming code.
