Align Phase
DG1000Z series dual-channel generators enable to align the phases of the two
channels. Pressing down this softkey 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, this operation will
align their phases. For example, assume a sine waveform (1kHz, 5Vpp, 0°) is
outputed from CH1, while another one (1kHz, 5Vpp, 180°) from CH2. Use an
oscilloscope to sample and display the two signals, you will see that the waveforms
shown on the oscilloscope do not always have a phase deviation of 180°. At this
point, press Align Phase on the generator and the waveforms shown on the
oscilloscope will have a phase deviation of 180° without any adjustment of the start
phase of the generator.

KET POINTS:
The Align Phase menu is grayed out and disabled when any
one of the two
channels is in modulation mode.
