<generator> 1 | 2
tracking generator
For Noise Figure measurements (K30): 1 only
Parameters:
<Value> <numeric value>
*RST: 1
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)"
on page 489
SOURce<n>:EXTernal<generator>:FREQuency:OFFSet<m> <Offset>
This command defines the frequency offset of the selected generator with reference to
the receive frequency.
This command is only valid for the External Tracking Generator option (R&S FSV-B10).

<m> 1 | 2
offset (for Noise Figure measurements (K30) only)
Parameters:
<Offset> <numeric value>, specified in Hz, kHz, MHz or GHz, rounded to
the nearest Hz
*RST: 0 Hz
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 analyzer:
For Noise Figure measurements (R&S FSV-K30), the following
formula applies:
Generator Frequency = [(LO + Offset 1) * Factor 1 / Factor 2)] +
Offset 2
Example:
SOUR:EXT:FREQ:OFFS 1GHZ
Sets a frequency offset of the generator transmit frequency com-
pared to the analyzer receive frequency of 1 GHz.
Mode: A, NF
