Universal Commands
Universal commands are encoded in the range 10 through 1F hex. They affect all
instruments connected to the bus and do not require addressing.
Command
Effect on the instrument
DCL (Device Clear)
Aborts the processing of the commands just received and sets the com-
mand processing software to a defined initial state. Does not change the
instrument settings.
IFC (Interface Clear) *)
Resets the interfaces to the default setting.
LLO (Local Lockout)
The "Local" softkey is disabled. Manual operation is no longer available
until
GTL
is executed.
SPE (Serial Poll Enable)
Ready for serial poll.
SPD (Serial Poll Disable)
End of serial poll.
PPU (Parallel Poll Unconfig-
ure)
End of the parallel-poll state.
*) IFC is not a real universal command, it is sent via a separate line; however, it also affects all instruments
connected to the bus and does not require addressing
Addressed Commands
Addressed commands are encoded in the range 00 through 0F hex. They only affect
instruments addressed as listeners.
Command
Effect on the instrument
GET (Group Execute Trigger)
Triggers a previously active instrument function (e.g. a sweep).
The effect of the command is the same as with that of a pulse at
the external trigger signal input.
GTL (Go to Local)
Transition to the "local" state (manual control).
Transition to the "remote" state (remote control).
PPC (Parallel Poll Configure)
Configures the instrument for parallel poll.
SDC (Selected Device Clear)
Aborts the processing of the commands just received and sets the
command processing software to a defined initial state. Does not
change the instrument setting.
GPIB Instrument Address
In order to operate the instrument via remote control, it must be addressed using the
GPIB address. The remote control address is factory-set to 20, but it can be changed if
it does not fit in the network environment. For remote control, addresses 0 through 30
are allowed. The GPIB address is maintained after a reset of the instrument settings.
Setting the GPIB address
1. On the R&S
ESR, press the [SETUP] key.
2. Press the "General Setup" softkey.
3. Press the "GPIB" softkey.
