An AWG70002B was used to create a pair of 20us wide RF pulse trains at 3.85GHz. One pulse train has a constant/unchanging phase – this is our reference and is applied to Ch1. The other pulse train steps between four different phase offset values with respect to the reference pulse train, and is applied to Ch2. The Phase deviation vs. Time traces are enabled on each channel. Channel 1 is setup as the Master Phase Reference for all channels and the phase reference location is set to approximately the middle of the 20us pulse. Bookmark callouts are used to show the phase values in each pulse on-screen.
