3.8 Programming and alignment Guidance ˺ The best downstream RF input level at the first amplifier stage is 72 dBµV (12 dBmV) when all the channels are flat. ˺ The total amplifier DS gain (with 0 dB attenuation) is 44 dB. Hybrid in high power mode The maximum RF output level loaded with 120 QAM channels 8 MHz is 112 dBµV (52 dBmV) with 9 dB tilt. - Page 17 Electronic setup of downstream and upstream Using a laptop with the Technetix BLL software installed connect to the amplifier with the appropriate USB-A to USB-A lead. The amplifier must be powered before you can configure it. (Fig. 8) Fig. 8 The BLL software will automatically connect to the DBC-1200 Lite amplifier.
