R&S ESU
6.17.2 SOURce:EXTernal Subsystem
The SOURce:EXTernal subsystem controls the operation of the unit with option Ext. Generator Control
(R&S FSP-B10). The commands are only valid for the selected window, with SOURce1 changing the
setting in screen A and SOURce2 the setting in screen B.
The selection of the external generator 1 or 2 is via EXTernal<1|2>.
The commands of the SOURce:EXTernal subsystem assume that the addressed
generator was correctly configured with the commands of subsystem SYSTem:
COMMunicate:GPIB:RDEVice:GENerator.
If no external generator is selected, if the GPIB address is not correct or the gener-
ator is not ready for operation, an execution error will be generated.
SOURce<1|2>:EXTernal<1|2>[:STATe] ON | OFF
This command activates or deactivates the external generator selected with SOUR:EXT<1|2>:FREQ:
SWE ON in the selected window.
The suffix behind EXTernal is irrelevant for this command.
This command is only available in connection with option Ext. Generator Control R&S FSP-B10.
Example:
"SYST:COMM:RDEV:GEN1:TYPE 'SMP02'"
'Selects SMP02 as generator 1.
"SYST:COMM:RDEV:GEN1:LINK TTL"
'Selects GPIB + TTL link as interface.
"SYST:COMM:RDEV:GEN1:ADDR 28"
'Sets the generator address to 28.
"SOUR:EXT1:FREQ:SWE ON"
'Activates the frequency sweep for generator 1.
"SOUR:EXT ON"
'Activates the external generator
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: R, A
SOURce<1|2>:EXTernal<1|2>:FREQuency[:FACTor]:DENominator <numeric_value>
This command defines the denominator of the factor with which the analyzer frequency is multiplied in
order to obtain the transmit frequency of the selected generator 1 or 2 in the selected window.
Select the multiplication factor in a way that the frequency range of the generator
is not exceeded by the following formula:
F
Generator
if applied to the start and stop frequency of the analyzer.
This command is only valid in combination with option Ext. Generator Control
R&S FSP-B10.
