Phase Offset
Set the phase offset of the RF signal.
When multiple RF signal generators are used to output signals, you can adjust the
phase offset of the instrument to synchronize the phase or set a fixed phase offset
for the signals.
Press FREQ  Phase Offset, after that use the numeric keyboard to input the
value of the phase offset and press deg or the unit key.
 Press Enter to select the default unit (deg).
 Press the left/right direction keys to enter the parameter editing state.
 You can also use the up/down direction keys or knob to modify the phase offset
at the current step.
 Press FREQ  Phase Offset and then press Step to set the step.
 Press Rst Phase to reset the current phase offset to 0 deg.
Explanation
1. When the frequency offset is 0 Hz, the frequency displayed in the interface
(namely setting frequency) is equal to the actual output frequency.
2. When frequency offset is not 0 Hz, the output frequency is determined by
setting frequency and frequency offset. The three parameters satisfy the
equation: setting frequency (display frequency) = output frequency +
frequency offset
3. The deviation (namely the actual output frequency) between interface display
frequency and frequency offset cannot exceed the frequency range of
instrument.
