Align Phase
DG800 series dual-channel function/arbitrary waveform generator enables you to
align the phases of the two channels. Press Align on the front panel, then the
instrument will re-configure the two channels and enable the generator to output
with specified frequency and start phase.
For two signals whose frequencies are the same or in multiple relationship, this
operation can align their phases. For example, assume a sine waveform (1 kHz, 5
Vpp, 0°) is output from CH1, while another one (1 kHz, 5 Vpp, 180°) from CH2. Use
the oscilloscope to acquire the waveforms of the two channels and stably display the
waveforms. It can be found that the phase deviation between the two waveforms is
no longer 180°. At this point, press Align on the generator and the waveforms
shown on the oscilloscope will have a phase deviation of 180° without manual
adjustment of the start phase of the generator.
