Controls description

Setting the return path

Select the return path band (WB up to 300MHz or NB up to 42MHz).

Narrow band (NB): Select the best combination of attenuators up to measure 16-17 dBmV per channel in the return path test point. This measure was done with 6 channels.
Wide band (WB): Select the best combination of attenuators up to measure 10-12dBmV per channel in the return path test point. This measure was done with 28 channels.
