GPIB Interface (IEC/IEEE Bus Interface)
The R&S
SGU is not equipped with an IEC/IEEE bus interface.
To be able to control the instrument via the GPIB bus:
1. Connect a GPIB-to-LAN or a GPIB-to-USB adapter to the instrument.
2. Use a GPIB bus cable to connect the instrument and the controller.
3. Provide the GPIB bus card, the card drivers and the program libraries for the pro-
gramming language in the controller.
4. In the "SGMA-GUI > Setup > Instruments > instrument name > Remote Control",
set the "GPIB Address".
See
5. If the controller is equipped with several GPIB bus cards, define the used "Board
Number".
GPIB address
The controller must address the instrument with the GPIB bus channel. GPIB provides
channel addresses from 0 to 30.
The GPIB resource string is
GPIB::<address>[::INSTR]
, where:
●
GPIB
denotes the used interface
●
<address>
indicates the used channel
●
[::INSTR]
indicates the instrument resource class (optional)
Note:
If the VISA implementation supports the GPIB interface, you can optionally
define the VISA instrument control resource (INSTR). It is used to define the basic
operations and attributes for a device, such as reading, writing, or triggering.
Any connected IEC bus cable must be terminated by an instrument or controller.

Starting a Remote Control Session
The instrument and the controller have to be connected with a suitable cable and
switched on.
A remote control program must open a connection to the instrument, before it can send
commands to and receive device responses from the instrument.
