Frequency output
3.4.5.6.1 Redundancy mode
Description
Sets the Redundancy mode. The frequency on channel 3 will follow frequency on channel 2
with 90° or 180° shift.
Setting
Off. Channel 3 runs in independently; 90°. Channel 3 follows frequency on channel 2 with a
90° shift; 180°. Channel 3 follows frequency on channel 2 with a 180° shift
Default
Off. Channel 3 runs in independently
