Align Phase
DG900 Pro provides the Align Phase function. When the output mode is set to
Continuous (except noise and DC), Sweep mode (internal trigger), or Burst mode
(internal trigger), click or tap the Align Phase key at the bottom. The instrument will
adjust the phase settings of the two channels and set an internal zero-phase
reference point.
For two signals whose frequencies are identical or in multiple,you can use this
function to align their phases. For example, the instrument outputs a sine waveform
(1 kHz, 5 Vpp) with 0° phase from CH1 and a sine waveform (1 kHz, 5 Vpp) with 180°
phase from CH2. Use an oscilloscope to acquire waveforms from the two channels
and then display the acquired two waveforms. You will see that the waveforms shown
on the oscilloscope do not always have a phase deviation of 180° At this point, click
or tap the Align Phase key. The waveforms shown on the oscilloscope will have a
phase deviation of 180° without any adjustment of the start phase of the generator.
