Operating Manual 1407.6062.32 ─ 08
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.
SCPI command:
5.4.2.3
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/LO Coupling" dialog, select "RF/A Mod > Configure
> Frequency" or use the MENU key under "RF/A Mod".
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
The lower parts concern the settings of the local oscillator (LO) and are described in
chapter 5.4.5, "Local Oscillator - LO Coupling"
Frequency Settings
The frequency, offset and multiplier factor are set in the top section of the menu.
Frequency - RF Signal
Sets the RF frequency of the RF output connector. The frequency entered and displayed
here corresponds to the frequency at the RF output, i.e. any offset entry is not taken into
consideration.
Note:
The SCPI command
SOUR:FREQ
sets the frequency of the "FREQ" display, i.e.
the frequency containing offset.
SCPI command:
n.a.
