R&S ESU
SYSTem:COMMunicate:GPIB:RDEVice:COMMand 0...30,<'command string'>
This command sends a command or query string to the external generator connected via the GPIB
interface of the Ext. Generator Control, R&S FSP-B10. Usually an external generator is connected to
this interface.
Only basic I/O is possible.
The first parameter is the GPIB address of the device connected with GPIB inter-
face of option FSP-B10.
The command is only available with option Ext. Generator Control, R&S FSP-B10.
Parameter: 0...30: GPIB address of the external generator connected via the GPIB interface of
the Ext. Generator Control, R&S FSP-B10. In the following example, the GPIB
address is 18.
"SYST:COMM:GPIB:RDEF:COMM 18,'*RST'"
'Resets generator.
"SYST:COMM:GPIB:RDEF:COMM 18,'SOURCE:FREQ:CW 2E9'"
'Sets generator frequency to 2 GHz.
"SYST:COMM:GPIB:RDEF:COMM 18,'SOUR:POW 0'"
'Sets generator power to 0dBm.
"SYST:COMM:GPIB:RDEF:COMM? 18,'SENS:POW?'"
'Queries the generator power.

SYSTem:COMMunicate:RDEVice:GENerator<1|2>:LINK GPIB | TTL
This command selects the interface type of the external generator 1 or 2.
The following types are available
• GPIB alone (= GPIB, for all the generators of other manufacturers and some Rohde & Schwarz
units)
• GPIB and TTL interface for synchronization (= TTL, for most of the Rohde & Schwarz generators,
see table in command SYSTem:COMMunicate:RDEVice:GENerator:TYPE).
The difference between the two operating modes is the execution speed. While, during GPIB
operation, each settable frequency is transmitted separately to the generator, a whole frequency list
can be programmed in one go if the TTL interface is also used. Frequency switching can then be
performed per TTL handshake which results in considerable speed advantages.
Only one of the two generators can be operated via the TTL interface at a time.
The other generator must be configured for GPIB.
The command is only available with option Ext. Generator Control, R&S FSP-B10.
Example:
"SYST:COMM:RDEV:GEN:LINK TTL"
'Selects GPIB + TTL interface for generator operation
