the desired offset value and unit.
Note: The offset value contains three effective digits. For example, when the
amplitude is set to 10 mVpp (the impedance is 50 Ω), the offset range calculated
is from -1.245 V to 1.245 V, while the actual offset range is -1.24 V to 1.24 V.

5. Set the start phase
Press StartPhase to set the start phase of the signal. The range is from 0°to
360°.
Method 1:
Rotate

and the numeric keyboard is displayed. Use the knob to input
the desired value and unit.
6. Align Phase
Pressing AlignPhase will re-configure the two channels to output according to
the preset frequency and phase. For two signals of which the frequencies are the
same or are multiples, this operation can align their phase. Acquire the
waveforms of the two channels using the oscilloscope and display the waveforms
stably. After switching the channel status, the phase deviation between the two
waveforms is changed. At this point, press AlignPhase and the phase deviation
shown on the oscilloscope will restore to the current phase deviation between
the two waveforms automatically.
