Frequency Settings

Access:

 

Select "RF > config... > RF Frequency > Frequency/Phase".

 

In the upper section of the combined "RF Frequency / Phase ..." settings dialog, you can configure the frequency of the RF signal.

The remote commands required to define the settings are described in "SOURce:FREQuency Subsystem".

Frequency

Sets the RF frequency of the RF output connector. The frequency entered and displayed 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.
Remote command: 

[:SOURce<hw>]:FREQuency[:CW|FIXed]

Note: This command sets the frequency of the "FREQ" display, that is the frequency containing offset.

 
Offset

Sets the frequency offset relative to the RF frequency. The frequency offset of a downstream 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 frequency in the header corresponds to the frequency at the output of the downstream instrument, see also "RF Frequency vs. RF Output Frequency".

Remote command: 
 
Main Pll Bandwidth

Selects the PLL (Phase Locked Loop) bandwidth of the main synthesizer.

Refer to "The Configurable Main PLL Bandwidth" for details.

"Normal"

Sets the default main PLL bandwidth. The instrument provides the maximum modulation bandwidth and FM / PhiM deviation.

"Narrow f<3GHz"

Sets the narrow PLL bandwidth.

Remote command: 
 
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 SMA, see also "RF Frequency vs. RF Output Frequency".

Remote command:
