The remote commands required to define the settings are described in Chapter 7.13.4,
"SOURce:FREQuency Subsystem" , on page 340.
Frequency
Sets the RF frequency of the RF output connector. The frequency entered and dis-
played here corresponds to the frequency at the RF output, that means any offset entry
is not considered.
Note: Suppressed values in the status bar
For security concerns or certain operating modes you can hide the frequency and level
display in the status bar.
●
The display has been disabled for security reasons, see Annotation Frequency and
Annotation Amplitude .
●
The display is disabled when list mode is running, see "State - List Mode"
on page 189.
Remote command:
[:SOURce<hw>]:FREQuency[:CW|FIXed]
on page 341
Note: This command sets the frequency of the "FREQ" display, that is the frequency
containing offset and multiplier.
Offset
Sets the frequency offset relative to the RF frequency. The frequency offset of a down-
stream instrument (for example a mixer) is entered.
The entry does not change the value of the RF frequency at the RF output. It only
changes the RF frequency displayed in the display header. The value of the RF fre-
quency in the header corresponds to the frequency at the output of the downstream
instrument, see also
Chapter 5.3.2.1, "RF Frequency vs. RF Output Frequency" ,
on page 137.
Remote command:
[:SOURce<hw>]:FREQuency:OFFSet
on page 344
Multiplier
Sets the multiplication factor for the RF frequency.
In the frequency field of the status bar, the instrument adjusts its frequency display
according to the set multiplication factor. This frequency value shows the frequency at
the output of the downstream multiplier. The entry does not change the RF frequency
at the RF output of the R&S
SMB, see also Chapter 5.3.2.1, "RF Frequency vs. RF
Output Frequency" , on page 137.
Remote command:
[:SOURce<hw>]:FREQuency:MULTiplier
