Socket connections are established on a specially defined port. The socket address is
a combination of the IP address or the host name of the instrument and the number of
the port configured for remote-control. All R&S SMB use port number 5025 for this pur-
pose. The port is configured for communication on a command-to-command basis and
for remote control from a program.
6.1.3.4 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.
&GTL 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.)
&GTR 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 &GTR.)
&POL Serial Poll Starts a serial poll.
6.1.4 USB Interface
For remote control via the USB connection, the PC and the instrument must be con-
nected via the USB type B interface. A USB connection requires the VISA library to be
installed. VISA detects and configures the R&S instrument automatically when the
USB connection is established. You do not have to enter an address string or install a
separate driver.
USB address
The used USB address string is:
USB::<vendor ID>::<product ID>::<serial number>[::INSTR]
