2.2.2 Softkeys of the Frequency Menu – FREQ Key (Analog Demodula-
tion)
The following table shows all softkeys available in the "Frequency" menu in "Analog
Demodulation" mode ([FREQ] key). It is possible that your instrument configuration
does not provide all softkeys. If a softkey is only available with a special option, model
or (measurement) mode, this information is delivered in the corresponding softkey
description.

Center
Opens an edit dialog box to enter the center frequency. The allowed range of values
for the center frequency depends on the frequency span.

If the bandwidth extension option R&S FSV-B160 is active, center frequencies above
7 GHz are not available.

CF Stepsize
Opens a submenu to set the step size of the center frequency. Apart from the =Center
and Manual softkeys, the other softkeys are displayed depending on the selected fre-
quency span.
The step size can be coupled to the span (span > 0) or the demodulation bandwidth
(span = 0) or it can be manually set to a fixed value.
0.1*Span (RF Spectrum) ← CF Stepsize
Sets the step size for the center frequency to 10 % of the span.
