been standardized by the SCPI committee. These commands are marked as
"SCPI compliant" in the command reference chapters. Commands without this
SCPI label are device-specific, however, their syntax follows SCPI rules as per-
mitted by the standard.
Instrument responses
Instrument responses (response messages and service requests) are messages that
the instrument sends to the controller after a query. They can contain measurement
results, instrument settings and information on the instrument status.
A.3.2 LAN interface messages
In the LAN connection, the interface messages are called low–level control messages.
These messages can be used to emulate interface messages of the GPIB bus.
Command Long term Effect on the instrument
&ABO Abort Aborts processing of the commands just received.
&DCL Device Clear Aborts processing of the commands just received and
sets the command processing software to a defined initial
state. Does not change the instrument setting.
>L Go to Local Transition to the "local" state (manual control). (The
instrument automatically returns to remote state when a
remote command is sent UNLESS &NREN was sent
before.)
>R Go to Remote Enables automatic transition from local state to remote
state by a subsequent remote command (after &NREN
was sent).
&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.
&LLO Local Lockout Disables transition from remote control to manual control
by means of the front panel keys.
&NREN Not Remote Enable Disables automatic transition from local state to remote
state by a subsequent remote command. (To re-activate
automatic transition use >R.)
&POL Serial Poll Starts a serial poll.
