♦ Channel SYNC Function: Support waveform copy and state copy between channels.

Support two or more signal generators connected to achieve multi-channel output, the maximum support 16-channel synchronous output, the phase between each channel can be adjusted.

♦ Precisely adjust the phases of the two channels, P'recision can be 0.01°.
