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
CALL IBFIND("DEV1", generator%)
b) Inform controller about instrument address
CALL IBPAD(generator%, 28)
c) Reset instrument
CALL IBWRT(generator%, "*RST;*CLS")
d) Set instrument to new address
CALL IBWRT(generator%, "SYST:COMM:GPIB:ADDR 18")
e) Inform controller about new address
CALL IBPAD(generator%, 18)
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.
6.2.3.2 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 SMC. 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 SMC's hostname or IP address. See also Chapter 6.1.3, "LAN Interface",
on page 192.
In this example, it is assumed that:
●
A LAN remote control link between the controller and the R&S SMC is already set
up.
●
The R&S VISA program is installed on the remote PC, see "http://www.rohde-
schwarz.com/rsvisa > RS VISA Release Notes".
Configuring the controller
To remote control the R&S SMC, we use the R&S VISA Tester application.
