Sets the user-defined step width. This step width is used when entering the RF frequency
using the rotary knob. Frequency variation with this step width must also be activated
with "Variation Active".
SCPI command:
[:SOURce<hw>]:FREQuency:STEP[:INCRement] on page 719
Variation Active - RF Signal
Activates the user-defined step width used when varying the frequency value with the
rotary knob.
"ON"
The frequency value set with the rotary knob is varied using the user-

5.5.3 Phase Settings
The phase of the RF output signal can be changed in the "Phase Settings" section of the
"RF Frequency/Phase" menu.
5.5.3.1 Phase Menu
To open the "Frequency/Phase" menu, select "RF/A Mod" > "Configure" > "Frequency/
Phase" or use the MENU key under RF/A Mod.
Delta Phase - RF Signal
Sets the phase of the RF signal. The current phase of the signal is used as the reference.
This function allows, for example, the phase of the output signal to be synchronized with
the phase of a signal from a second signal generator.
SCPI command:
[:SOURce<hw>]:PHASe on page 760
Reset Delta Phase Display - RF Signal
Resets delta phase value. The set phase is adopted as the new current phase, i.e. the
delta phase value is reset to 0.
SCPI command:
[:SOURce<hw>]:PHASe:REFerence on page 761
