User Manual 1178.3834.02 ─ 03
To be able to control the instrument via the GPIB bus, the instrument and the controller
must be linked by a GPIB bus cable. A GPIB bus card, the card drivers and the pro-
gram libraries for the programming language used must be provided in the controller.
GPIB address
The controller must address the instrument with the GPIB bus channel (see
ter 11.4.3, "GPIB Address Settings"
on page 260). GPIB provides channel addresses
from 0 to 30.
The GPIB resource string syntax is as follows:
GPIB
= denotes the used interface
<channel address> = 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.
Notes and characteristics
In connection with the GPIB interface, note the following:
●
Up to 15 instruments can be connected.
●
The total cable length is restricted to a maximum of 15 m, or 2 m times the number
of devices, whichever is less. The cable length between two instruments should not
exceed 2 m.
●
A wired "OR"-connection is used if several instruments are connected in parallel,
since the slowest instrument determines the speed.
Any connected IEC bus cable must be terminated by an instrument or controller.
11.2.4 LXI Browser Interface
The LXI browser interface allows easy configuration of the LAN and remote control of
the R&S
SMA100B without additional installation requirements. The instrument's LXI
browser interface works correctly with all W3C compliant browsers.
See
Chapter 11.17.1, "LXI Functionality"
on page 301 for more about LXI.
The LAN settings are configured using the instrument's LXI browser interface descri-
bed in
Chapter 11.5.2.1, "LAN Configuration"
on page 267. The LXI status settings in
the R&S
SMA100B are described in
Chapter 11.5.1, "LXI Status Settings"
