communication reference
When the auxiliary frequency source is used as independent frequency reference
channel ,it is used in the same way as the main frequency source X
when the auxiliary frequency source is used as overlap reference (i.e. frequency
source selection switching from X plus Y or X to X plus Y) ,special points as
follows:
1、When the auxiliary frequency source is the digital reference ,the present
frequency (FO-11) has no action in need of adjusting the main reference frequency
through the key ▲and ▼on the keyboard (or UP and DOWN of multifunction input
terminals)
2、When the auxiliary frequency source is the analog input reference (A11,A12)
100% of input setup is relative to the auxiliary frequency source range(refer to
F0-08-F0-09).In need to adjust the main reference frequency, please set the
corresponding setup range of analog input to “-n% to n%(refer to F5-15 and F5-24)
Prompt : there is difference between the auxiliary frequency source Y selection and
the main frequency source X set up value ,that is to say, the main and auxiliary
frequency sources cannot use the same frequency reference channel.
