Fixed frequency ratio (RATIO) (
CHANNEL MODE
: RATIO)
Following is a description of the ratio channel mode whereby a fixed frequency ratio is maintained
between the frequencies of CH1 and CH2 (or vice versa).
In this mode, if the frequency of either channel is changed, the frequency of the other channel is
automatically changed to maintain the fixed ratio.
Operation:
(1)
Set the channel mode to ratio
