3.1.13 SOURce Subsystem
The SOURce:EXTernal subsystem controls the operation of the unit with option Ext.
Generator Control (FSP-B10).
SOURce:EXTernal:FREQuency:OFFSet<1|2> <numeric value> <numeric value>
This command defines the frequency offset of the selected generator with reference to
the receive frequency.
NOTICE!
Select the frequency offset of the generator so that the frequency range of the
generator is not exceeded with the following formula.

This command is only valid in combination with option Ext. Generator Control R&S
FSP-B10.
Example
"
SOUR:EXT:FREQ:OFFS 1GHZ
"
sets a frequency offset of the generator transmit frequency
compared to the analyzer receive frequency of 1 GHz.

SOURce:EXTernal:FREQuency[:FACTor]:NUMerator <numeric value> <numeric
value>
This command defines the numerator of the factor with which the analyzer frequency is
multiplied in order to obtain the transmit frequency of the selected generator.
NOTICE!
Select the frequency offset of the generator so that the frequency range of the
generator is not exceeded with 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.
Example
SOUR:EXT:FREQ:NUM 4
SOUR:EXT:FREQ:DEN
'sets a multiplication factor of 4/3, i.e. the transmit
frequency of the generator is 4/3 times the LO frequency.
