Example: //Define multiplication factor of 4/3; the transmit frequency of the
generator is 4/3 times the analyzer frequency
SOUR:EXT:FREQ:NUM 4
SOUR:EXT:FREQ:DEN 3
Manual operation: See "(Automatic) Source Frequency (Numerator/Denominator/
Offset)" on page 397
SOURce<si>:EXTernal<gen>:FREQuency[:FACTor]:NUMerator <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.
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:

SOURce<si>:EXTernal<gen>:FREQuency:OFFSet <Offset>
This command defines the frequency offset of the generator with reference to the ana-
lyzer frequency.
Select the offset 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 analyzer:
