Enter Host Forward and Reverse Delay
The
forward and reverse delay function allows entry of from 0 to 63 µsec of delay in the
forward
and reverse paths. This feature is used when multiple systems are used to transport the
same
channel and there is a significant difference in the path delay between systems. Additional
delay
may be entered to balance the overall system delay. The amount of delay required must be
calculated
by the RF engineer and should be included in the system design plan. The default
setting
is 0 µsec. Use the following procedure to change the forward and reverse path delay:
1. Click
on the HOST RF tab. The HOST RF display will open within the EMS main
window
