Point, and Forward Telemetry Signals
The following worksheets will help you calculate the required levels for SDA-
5500 forward sweep.
Worksheet 1 Input Level Calculation
1. Enter the system level at the tap-off point
(video carrier level)
2. Subtract the directional coupler (DC) value
3. Subtract the pad value
4. Subtract the diplex filter loss (when used
it’s usually 1dB)
Input Level (best
between +4dBmV
and +10dBmV;
12dBmV max)
