VXI–11 Interface Messages
On the Ethernet link, the interface messages are called low–level control messages. These messages
can be used to emulate interface messages of the GPIB.
Table 5–14 VXI–11 Interface Messages
Command Effect on the instrument
&ABO (Abort) Aborts the processing of the commands just received.
&DCL (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.
>L (Go to Local) Transition to the "Local" state (manual operation)
>R (Go to Remote) Transition to the "Remote" state (remote control)
&GET (Group Execute
Trigger)
Triggers a previously active device 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 switchover from remote control to manual operation
by means of the front panel keys
&POL (Serial Poll) Starts a serial poll
&NREN (Not Remote Enable) Enables switchover from remote control to manual operation
by means of the front panel keys
RSIB Protocol Basics
The R&S defined RSIB protocol uses the TCP/IP protocol for communication with the instrument.
Remote control over RSIB is done on a message level basis using the SCPI command set of the
instrument. The RSIB protocol allows you to control the instrument not only via Visual C++– and Visual
Basic programs but also via the two Windows applications WinWord and Excel as well as via National
Instruments LabView, LabWindows/CVI and Agilent VEE. The control applications run on an external
computer in the network.
A UNIX operating system can be installed on an external computer in addition to a Windows operating
system. In this case, the control applications are created either in C or C++. The supported UNIX
operating systems include:
•Sun Solaris 2.6 Sparc Station
•Sun Solaris 2.6 Intel Platform
•Red Hat Linux 6.2 x86 Processors
