Narrow cast port setup
1.
Apply the QAM RF load to the NC input of the transmitter at 15dBmV
2. Set NC MGC back off to -6dB by subtracting 6dB from the BC MGC setting (1.6dB) 1.6 - 6 = -4.4dB
3. Set Narrowcast MGC to
-4.4dB
4. Hit apply button to store setting into the transmitter.
6.5 Setup using separate BC and NC RF input in AGC mode
Since no QAM RF signals are used in sample calculation 1 or 2, this setup will use sample calculation
3. For the exact RF calculation please refer to Chapter 6.1.1 sample calculation 3.
Sample calculation 3 details:
Total RF power
50 channels analogue = 50 analogue equivalent
13 x QAM @ -10dB
= 1.3 analogue equivalent
15 x QAM256 @ -6dB = 3.8 analogue equivalent
