Equipment Description
Diamond Line2 amplifiers have two equal, or three unequal,
high-level RF distribution outputs. They use two
post-amplifier hybrids, one for the main output and one for
the secondary outputs. A plug-in output port selector allows
you to use one or both secondary outputs by using a plug-in
jumper or directional coupler.
Figure 8. Diamond Line 2 Amplifier, Front View
The Diamond Line2 amplifier is a distribution amplifier, similar in
function to Philips’ GNA series global network amplifiers.

Functional Description
For details on the forward
RFsignal flow, see page35.
Fordetails on the return
RFsignal flow, see page38.
For a description of amplifier
powering, see page39.
In summary, forward RF signals enter the Diamond Line2
amplifier module through the input port, J1, and are amplified
by the pre-amplifier. The main output signals are amplified
twice more before exiting through the main output port, J2.
The secondary-output signals are also amplified twice more
before exiting through the two distribution (secondary)
output ports, J3 and/or J4.
The return RF signal flow is the same for all three of the
Diamond Line2 amplifier’s return legs, from ports J2, J3,
and/or J4 to portJ1.
Figure 11. Diamond Line 2 Amp, Functional Block Diagram
The Diamond Line2 amplifier can have two equal, or three
unequal, high-level RF distribution outputs. It uses two
post-amplifier hybrids, one for the main output and one for the
two secondary outputs. A plug-in output port selector lets you
use one or both secondary outputs by using a plug-in jumper or
directional coupler.

Diamond Line Amplifiers 10 July 2000 35
Diamond
Forward RFSignalFlow Before Main & Secondary Paths Split
Input Port (J1). The input port, J1, routes forward incoming
signal to the amplifier. (This port also routes outgoing return
signal to the main cable.)
Refer to Figure11 as you
read the descriptions in this
section.
Input Test Point. The input test point is a -20 dB directional
coupler. Accessible through a cut-out in the module cover,
this test point lets you verify the forward signals at the
forward input port(J1) without interrupting the amplifier’s
operation. (Return signal cannot be measured here.)
Input Diplex Filter. A diplex filter consists of a pair of filters, a
high-pass and a low-pass, isolating forward and return bands.
The high-pass filter passes forward signals but blocks return
signals and AC. The low-pass filter passes return signals but
blocks forwardsignals.
Amplifiers are shipped with
the input attenuator and
input equalizer positions
empty; you must plug both
circuits in for the amplifier to
work.
Input Attenuator. A 9-A-WC or 10-A-WC series plug-in
attenuator reduces RF levels at the pre-amp input to meet
design specifications. Amplifiers are shipped with the input
attenuator position empty. Select and install the appropriate
value based on the amplifier’s location in your network.
Input Equalizer. The 7-2E-WC series plug-in equalizer
compensates for the effects of cable precedingthe amplifier
module. Amplifiers are shipped with the input equalizer
position empty. Select and install the appropriate value based
on the amplifier’s location in your network.
Pre-Amplifier. A push-pull input hybrid provides gain. This
pre-amplifier sets the amplifier’s noise figure.
Interstage Attenuator. A 9-A-WC or 10-A-WC series
interstage attenuator reduces overall amplifier gain. A “zero”
attenuator is shipped in this slot for circuit continuity.
ALSC Bode Equalizer (factory-installed). The ALSC Bode
equalizer works with the ALSC Bode controller to maintain a
constant RF output level, compensating for the effects of
outside temperature changes on cable.
Response Equalizer. An EDB series response equalizer
(debumper) flattens the forward response of cascaded
amplifiers, compensating for system signature imperfections.
A jumper is shipped in this slot for circuit continuity.

36 10 July 2000 Diamond Line Amplifiers
ForwardRFSignalFlow
(Cont.) Interstage Equalizer (factory-installed). The 7-2E-WC series equalizer is factory-installed to optimize the distortion
characteristic of the amplifier and provide the desired main
output slope at the specified bandwidth. Normally you will
not change this plug-in. However, if you need to change the
tilt of the amplifier’s outputs from the factory-set value, see
the procedure under “Interstage & Distribution Equalizers”
on page160.
Interstage Amplifier. The RF from this hybrid, which uses
push-pull technology, goes to the two post-amplifiers.
ALSC Bode Controller (factory-installed). The automatic level
and slope control (ALSC) Bode controller works with the
ALSC Bode equalizer to maintain a constant RF output level,
compensating for the effects of outside temperature changes
on cable. A directional coupler taps a small portion of the
main output power and converts it to a DC signal that
controls the Bode equalizer.
Distribution Equalizer (factory-installed). The 7-2E-WC series
distribution equalizer provides additional slope to all outputs.
The interstage and distribution equalizers are factory-installed
to set the tilt of the output signals according to the customer
order. A “zero” equalizer may be shipped in the distribution
equalizer position for circuit continuity if no additional slope is
needed. Normally you will not change this plug-in. However,
if you need to change the tilt of the amplifier’s outputs from
the factory-set value, see the procedure under “Interstage &
Distribution Equalizers” on page160.
Main Path (after it splits from secondary path)
Main Output Attenuator. Accessible through a cut-out in the
module cover, this 9-A-WC or 10-A-WC attenuator reduces
signal levels at the main output. A “zero” attenuator is
shipped in this slot for circuit continuity.
Main Output Post-Amplifier. The RF from this hybrid, which
uses Power Doubling technology, goes to the main output
port, J2.
Main Output Diplex Filter. See “Input Diplex Filter” on
page35.

Diamond Line Amplifiers 10 July 2000 37
Diamond
The main output test point
allows access to the return
band as well. You can’t
measure return signal here,
but you can inject return test
signals.
Main Output Test Point. The main output test point is a
-20dB directional coupler, which isolates the measured
forward signal from the effects of reflections in the cable.
Accessible through a cut-out in the module cover, this test
point lets you verify the forward signals at the main output
port (J2) without interrupting the amplifier’s operation.
Main Output Port (J2). The main output port, J2, routes
forward outgoing signal to a distribution cable. (This port also
routes incoming return signal to the amplifier.)
Secondary Path (after it splits from main path)
Secondary Output Attenuator. A 9-A-WC or 10-A-WC series
attenuator reduces signal levels at the secondary output port
(J3 or J4). A “zero” attenuator is shipped in this slot for circuit
continuity.
Secondary Output Post-Amplifier. The RF from this hybrid,
which uses Power Doubling technology, goes to the
secondary output port(s).
Secondary Output Port Selector. Accessible through a cut-out
in the module cover, the output port selector directs signal to
the secondary output port(s): J3 only, J4 only, or both J3 and
J4. A jumper, or “zero” attenuator, is used when directing
signal to only one port.When using both ports, this location
accepts a DC4-WC, DC8-WC, or DC12-WC directional
coupler plug-in.
Secondary Output Diplex Filter. See “Input Diplex Filter” on
page35.
A secondary output test point
allows access to the return
band as well. You can’t
measure return signal here,
but you can inject return test
signals.
Secondary Output Test Point. A secondary output test point is
a -20 dB directional coupler, which isolates the measured
forward signal from the effects of reflections in the cable.
Accessible through a cut-out in the module cover, this test
point lets you verify the forward signals at the secondary
output port (J3 or J4) without interrupting the amplifier’s
operation.
Secondary Output Port (J3 or J4). A secondary output port
routes forward outgoing signal to a distribution cable. (This
port also routes incoming return signal to the amplifier.)

Return RF Signal Flow Before the Return Legs Combine
The signal flow is the same
for all three of the Diamond
Line2 amplifier’s return legs.
Refer to Figure11 as you
read the descriptions in this
section. See also “Accurate
return setup” on page10 for
a discussion of return-path
features and benefits.
Return Input Port (J2, J3, or J4). A return input port routes
incoming return signal to the amplifier. (This port also routes
forward outgoing signal to distribution cables.)
Return Test Signal Injection Point (Output Test Point). Since the
forward output test point allows access to the return band,
you can inject return test signals here (although you can’t
measure return signal).
Return Input Diplex Filter. See “Input Diplex Filter” on
page35.
Return Input Attenuator. A 9-A-WC or 10-A-WC series
plug-in attenuator is used in this position primarily for ingress
isolation. (See page163.) A “zero” attenuator is shipped in
this slot for circuit continuity.
Return Input Test Point. Accessible through a cut-out in the
module cover, this -20 dB resistive test point lets you verify
the return signals at the return hybrid input. It is
approximately -15dB from the test point’s position in the
circuit.
Return Combiner. Return signals from J2, J3, and J4 are
combined into a single feed for the return amplifier. This
three-way combiner has equal (5dB) loss in each leg.
After the Return Legs Combine
Return Amplifier. This hybrid, which amplifies the combined
return signal, features an improved compression point and bit
error rate (BER) for digital-loaded traffic over a discrete
amplifier design.
Amplifiers are shipped with
the return output equalizer
and return output attenuator
positions empty; you must
plug both circuits in for the
amplifier to work.
Return Output Equalizer. Accessible through a cut-out in the
module cover, the 7-REF-WC series equalizer provides an
output tilt at the return amplifier that will provide a flat input
at the next return amplifier. Amplifiers are shipped with the
return output equalizer position empty. Select and install the
appropriate value based on the amplifier’s location in your
network.
A return EDB plug-in may be installed instead of the
7-REF-WC series equalizer to flatten circuitry response
anomalies.

Diamond Line Amplifiers 10 July 2000 39
Diamond
Return Output Attenuator. A 9-A-WC or 10-A-WC series
attenuator reduces signal levels at the return output port (J1).
Amplifiers are shipped with a “zero” return output
attenuator. You may need to select and install the appropriate
value based on the amplifier’s location in your network.
Return Output Test Point. This -20 dB directional coupler test
point is used to measure the combined return signal as it will
be sent to the return output port, J1. (Note that the test
point at J1 is for forward input only; combined return signal
cannot be measured at that point.)
Return Output Diplex Filter. See “Input Diplex Filter” on
page35.
Return Output Port (J1). The return output port routes
outgoing return signal via the cable system back to the
previous amplifier. (This port also routes incoming forward
signal to the amplifier.)
Amplifier Powering AC power may enter the housing at any of the RF ports.
ACand RF separation is fixed. An AC bypass path provides
high impedance to RF signals.
The amplifier’s 3-ampere power supply receives the incoming
AC power and converts it into DC power. For details on the
power-director fuses, see Figure45.
