2.5 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 as shown in Figure 4-8.

2. Right-click on the Host Fwd Delay section of the display (see Figure 4-8). The Host Fwd
Delay pop-up screen will open as shown in Figure 4-9.
3. Obtain the value of the forward delay as specified in the system design plan.
4. Enter the forward path delay value and click OK to close the pop-up screen and to make
the changes take effect.
5. Repeat the process for reverse delay and diversity reverse delay by right-clicking on the
appropriate delay section (see Figure 4-8) and then entering the required delay value in the
pop-up screen.
6. Click OK to close each pop-up screen and to make the changes take effect.
