3.5 RF Phase Settings
The phase in sinusoidal signals defines the initial angle at its origin.
Access:
1. Select "Frequency" > "Phase".
In the "RF Phase" tab, you can determine the delta phase value and reset the
phase to this reference.
2. Observe the information on the home screen, "Frequency" tile.
The "Frequency" tile indicates used reference frequency, current frequency offset
and multiplier values, and the delta phase value.
