Remote Control over GPIB

The program example in this section is written in VISUAL BASIC. A condition for pro-
gramming in VISUAL BASIC is that the modules NIGLOBAL (Niglobal.bas) and
VBIB32 (Vbib_32.bas) are added to the projects.
Drivers for instrument, e.g. IVI-COM and LabVIEW drivers, are available in the down-
load area of the product website
test_and_measurement/product_categories/signal_generation/).
Starting a remote control session over GPIB
As a prerequisite, the GPIB address of the instrument, which is factory-set to 28, must
not have been changed.
1. Connect instrument and controller using GPIB cable and switch them on.
2. Execute following commands on the controller:
a) Open port to the instrument
b) Inform controller about instrument address
c) Reset instrument
d) Set instrument to new address
e) Inform controller about new address
The GPIB address of the instrument is changed.
3. To return to manual operation sent CALL IBLOC (generator%) or press the
LOCAL key at the front panel.

Remote Control over LAN using VXI-11 Protocol

In this example, the I/O software library R&S VISA from Rohde & Schwarz is used to
set up a LAN remote control link and remotely control the R&S SMB. R&S VISA is run-
ning on a controller PC with Windows operating system. When the connection is set up
you can send commands to the instrument, and receive the responses.
The remote control connection requires a VISA installation but no additional hardware
on the controller PC. The LAN I/O channel is selected at initialization time using the
VISA resource string (also referred to as "address string"). A VISA alias (short name) is
used to replace the complete resource string. The host address is either the
R&S SMB's hostname or IP address. See also
on page 237.
