c) While using the socket communication, terminate the remote control session.
d) Send the interface command >L via the remote control interface.
Tip: Use the &NREN to enable the LOCAL key if the key is disabled.
6.2.3 Examples
This sections provides examples for setting up of remote control connection and starting
a remote control session over LAN and GPIB interfaces.
This section assumes basic knowledge of programming and operation of the controller.
A description of the interface commands can be obtained from the relevant manuals.
6.2.3.1 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 download
area of the product website (http://www2.rohde-schwarz.com/en/products/
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
CALL IBFIND("DEV1", generator%)
b) Inform controller about instrument address
CALL IBPAD(generator%, 28)
c) Reset instrument
CALL IBWRT(generator%, "*RST;*CLS")
d) Switch on the analog I/Q outputs
CALL IBWRT(generator%, "IQ:OUTP:STAT ON")
e) Set modulation type to FSK2
CALL IBWRT(generator%, "BB:DM:FORM FSK2")
f) Switch on digital modulation
CALL IBWRT(generator%, "BB:DM:STAT ON")
The set modulation signal is now applied at the analog I/Q-output of the instrument.
3. To return to manual operation, press the LOCAL key at the front panel.
