Appendix

The channel coupling implements a much tighter coupling of channel 1 and
channel 2.
When channel coupling is enabled, the two channels are not only locked in
frequency, but also in phase. Additionally, all timing relevant parameters will
be updated between the channels automatically (refer to the Appendix for
the complete list of coupled parameters) to ensure that the frequency and
phase remain locked when changing the instrument’s state.
The initial update when enabling channel coupling can be done from
channel 1 to channel 2 or from channel 2 to channel 1, depending on which
channel is being used to enable the channel coupling. All following updates
are done from channel 1 to channel 2 or from channel 2 to channel 1,
depending on where the change was done.
