R&S FSW-K7
Using this offset, attenuators or amplifiers at the output connector of the external gen-
erator can be taken into account. This is useful, for example, for the displayed output
power values on screen or during data entry. Positive offsets apply to an amplifier,
while negative offsets apply to an attenuator after the external generator.

Source Frequency Coupling
Defines the frequency coupling mode between the R&S FSW and the generator.

(Manual) Source Frequency
Defines the fixed frequency to be used by the generator.

(Automatic) Source Frequency (Numerator/Denominator/Offset)
With automatic frequency coupling, a series of frequencies is defined (one for each
sweep point), based on the current frequency at the RF input of the R&S FSW.
However, the frequency used by the generator may differ from the input from the
R&S FSW. The RF frequency can be multiplied by a specified factor, or a frequency
offset can be added, or both.
Note: The input for the generator frequency is not validated, i.e. you can enter any val-
ues. However, if the allowed frequency ranges of the generator are exceeded, an error
message is displayed on the R&S FSW. The values for
Result Frequency Stop
The value range for the offset depends on the selected generator. The default setting
is 0 Hz. Offsets <> 0 Hz are indicated by the "FRQ" label in the channel bar. Negative
offsets can be used to define reverse sweeps.
