6. Align Phase
The align phase operation is for the two channels. 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 phases. 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.
7. Select waveform
Select the arbitrary waveform in the internal or external memory. For the detailed
operation, please refer to the introduction in "To Select Waveform".
8. Create waveform
Users define their own arbitrary waveform. For the detailed operation, please
refer to the introduction in "To Create Waveform".
9. Edit waveform
Edit the arbitrary waveform stored. For the detailed operation, please refer to the
introduction in "To Edit Waveform".
10. Modulation
Press Src1Mod to enter the modulation setting interface. For detailed
introduction of the modulation function, please refer to " Modulation".
11. Set the impedance
Press Impedance to set the output impedance of the signal generator. It can be
set to "HighZ" or "50Ω".
The following section introduces how "To Select Waveform", "To Create
Waveform" and "To Edit Waveform".
To Select Waveform
Users can load the waveform stored or recall the channel signal waveform according
to their needs.
 Load
Select arbitrary waveforms in the internal or external memory (D disk) for output.
Press Select  Load, use to select the desired waveform. For the detailed
operation, please refer to the introduction in "Store and Recall".
 Channel Signal
Select the signals of analog channel (CH1-CH4) turned on currently for output.
