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.
Remote command:
[:SOURce<hw>]:PHASe on page 334
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.
Remote command:
[:SOURce<hw>]:PHASe:REFerence on page 335
5.3.4 Reference Oscillator
In the internal reference mode the internal reference signal is available at the REF
OUT connector. The frequency of the internal reference signal is permanently set to 10
MHz.
