Crosstalk (typical):
The channels are independent of each other.
The two channels are identical and behave identically.
The two channels are identical except that the output of channel 2 is
inverted. In this mode the two channels can be used together as a
differential signal source.
The frequencies of the two channels can be coupled. Changing the
frequency of one channel changes the frequency of the other channel,
either by a fixed ratio or fixed offset.
Waveforms
Type
Amplitude (and DC offset) of the two channels can be coupled.
Changing the amplitude and offset on one channel changes the
amplitude and offset of both channels.
Output On/Off can be coupled. Switching the output On/Off on one
channel switches the output On/Off of both channels.

Sine, Square, Ramp and Arbs can be coupled to
each other. Pulse can only be coupled to Pulse.
