R&S FSP Remote Control – Description of Commands
SOURce Subsystem
6.210 Operating Manual 1164.4556.12 - 06
6.17.2 SOURce:EXTernal Subsystem
The SOURce:EXTernal subsystem controls the operation of the unit with option Ext. Generator Control
(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>.
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.
Example:
"SOUR:EXT:FREQ:NUM 4"
"SOUR:EXT:FREQ:DEN 3"
'Sets a multiplication factor of 4/3, i.e. the transmit frequency of the generator is 4/
3 times the analyzer frequency.
Characteristics: *RST value: 1
SCPI: device-specific
Mode: A
SOURce<1|2>:EXTernal<1|2>:FREQuency[:FACTor]:NUMerator <numeric_value>
This command defines the numerator of the factor with which the analyzer frequency is multiplied to
obtain the transmit frequency of the selected generator 1 or 2 in the selected window.
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.
Select the multiplication factor in a way that the frequency range of the generator
is not exceeded by the following formula:
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.
