SOURce<n>:EXTernal<generator>:FREQuency[:FACTor]:DENominator <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.
This command is only valid for the External Tracking Generator option (R&S FSV-B10).
Select the multiplication factor such that the frequency range of the generator is not
exceeded if the following formula is applied to the start and stop frequency of the ana-
lyzer:

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.
Mode: A, NF
Manual operation: See "Generator Frequency (Numerator/Denominator/Offset)"
