Align Phase
Pressing Align Phase will re-configure the two channels and enable the generator to
output with the specified frequency and start phase. Note that the align phase
function is only for dual-channel models.
For two signals whose frequencies are the same or in multiple, this operation will align
their phase. For example, assume a sine waveform (1 kHz, 5 Vpp, 0 °) is outputted
from CH1, while another (1 kHz, 5 Vpp, 180°) from CH2. Use an oscilloscope to
sample and display the two signals stably. You will see that the waveforms shown on
the oscilloscope do not always have a phase deviation of 180°. Now, press Align
Phase on the generator. The waveforms shown on the oscilloscope will have a phase
deviation of 180° without any adjustment of the start phase of the signal generator.

Note: For dual-channel models, the Align Phase menu is grayed and disabled when
any one of the two channels is in modulation mode.
