If you have the R&S SMB equipped with one of the options R&S SMB-B112, -B120, or -
B140, you can, in addition, operate an R&S SMZxx frequency multiplier. xx represents
the multiplier type that you can use according to the target frequency range.
5.3.2.2 Setting the RF Frequency
To change the RF frequency, press the FREQ key and enter the desired frequency.
Changes to the RF frequency have an immediate effect (without confirmation with the
ENTER key) on the output signal.
RF Freq
Enters the RF frequency, considering the frequency offset.
Note: The SCPI command sets the level of the "Freq" display, i.e. an entered frequency
offset and multiplier factor are taken into consideration in the frequency value.

5.3.2.3 RF Frequency Dialog
In the combined "Frequency/Phase" dialog, you can enter the frequency, the frequency
offset and multiplication factor of a downstream instrument, set the step width for the
frequency entry using the rotary knob, and set the phase for the RF output signal.
To open the "RF Frequency / Phase" dialog, select "RF" > "Configure" > "Frequency" or
use the MENU key under "RF".
The "RF Frequency / Phase" dialog is divided into the several sections.
Frequency and offset of the RF output signal are set in the "Frequency Settings" section
in the upper part of the dialog. In addition, the multiplier factor of an externally connected
multiplier is specified.
The step width which is used when setting the frequency using the rotary knob (with
"Variation Active On") is set in the "User Variation" section.
The phase of the output signal can be changed in the "Phase Settings" section. The
"Phase Settings" menu is described in chapter 5.3.3, "Phase", on page 119.
Frequency Settings
The frequency, offset and multiplier factor are set in the top section of the menu.
