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.
