Align Phase
The align phase function is only for dual-channel models. Aligning phase is available
for the operation of 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 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, and then toggle the channel output switch of the
generator, you will see that the waveform 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 oscilloscope.
