5.6 Frequency and percentage reference channel
T
he varied functions for the specification of the reference values are connected in the
various configurations by the frequency or percentage reference channel. The
Refer-
ence frequency source
475, and the Reference percentage source 476 determine the
additive connection of the available reference sources as a function of the installed
hardware.
