SDA-5500/SDA-5510 Sweep Configuration: Using Both Headend Units

297

Fig. 14-20 A Second Method of Connecting the SDA-5500

for Forward and Reverse Sweep

The addition of the SDA-5510 to the Stealth sweep system takes the

responsibility for reverse sweep away from the SDA-5500, and serves to

speed both forward and reverse sweep rates. In addition, the SDA-5510

sends reverse ingress and noise information with every update of its forward

telemetry, so reverse telemetry need not be received to check the reverse

ingress condition.

To take full advantage the sweep speed increases in a system using both

units, be sure to disable the SDA-5500’s reverse sweep. Multi-user

contention can be eliminated by offsetting reverse channel plans, and by

using different telemetry frequencies.

The wiring configuration for a system using both units is shown in Figure 14-

21. Refer to Figure 14-12 for an example of a connection in a dual cable

network.
