to adjust RF level to the
ALC pilot. Changing the value of the ALC PAD lets the ALC
deliver an NTSC channel or a QAM signal that operates at a level
lower than the NTSC channels. (For example: If the QAM
channels are set at –6 dB from the NTSC channels, lower the
ALC PAD by 6dB).

O/P EQ
(Trunk amplifiers only. On
bridger amplifiers this
location is present on the
module cover, but there
is no plug-in location on
the PCB.)
Location on trunk amplifiers for installing:
■ an NPB-000 PAD to optimize standard 1GHz operation with
different tilts on the trunk and bridger ports (T:10dB, B:18dB)
■ a GEQC-1GHz-050, GEQC-1GHz-070, or GEQC-1GHz-090
equalizer to optimize 1GHz operation with equal tilt on the
trunk and bridger ports (14dB, 15.5dB, and 17dB respectively)
■ a GEQC-870-080 equalizer to optimize 750/870MHz operation
with equal tilt on the trunk and bridger ports (14.5dB)
11 MODULE HOLD DOWN One of four screws that secure the RF module in the housing.
12 PORT 4 REV I/P TP Directional testpoint for measuring inbound return RF signals.
13 PORT 4 FWD O/P TP Directional testpoint for measuring outbound forward RF signals.
14 PORT 4 Provides access to the Port 4 centerseizure screw (90° rotation).
15 PORT 4 Provides access to the Port 4 centerseizure screw.
16 ALC/MAN Selects either automatic level control or fixed gain control.
