PRELIMINARY - Motorola Internal Use Only SLE*-* Installation and Operation Manual
Housing
The SLE*-* is furnished in an aluminum housing that protects the electronics from weather and
dissipates internally generated heat.
Figure 2-3 illustrates the SLE*-* housing and provides its dimensions:
Figure 2-3
SLE*-* housing dimensions
10.75
inches

inches
Coaxial cable connections to the housing are made using conventional 5/8 inch ×24 threads-per-
inch stinger-type connectors.
For strand mounting, use the two messenger clamps located on the side of the housing
(Figure 2-5) that are secured with 5/16 inch ×24 threads-per-inch stainless steel bolts. Use the
“L”bracket feature for pedestal and surface mounting installations.

2-4 Overview
SLE*-* Installation and Operation Manual PRELIMINARY - Motorola Internal Use Only
Gaskets
Each housing is equipped with a recessed woven-wire RF gasket and a silicone-rubber gasket to
provide a seal between the housing base and lid. These gaskets provide efficient ground
continuity, RF shielding, and weather protection. Both gaskets must be in place and in good
condition to ensure proper operation and protection of the station. The weather gasket should be
lightly coated with silicone grease each time the SLE*-* is opened. Replace this gasket if it
becomes damaged or deformed.

Port Locations
Three housing ports provide connection for coaxial cables (one is for the optional second output).
A fourth housing port provides access to the return-path RF test point. All ports are protected
by factory-inserted threaded plugs or plastic cap plugs. Discard the plastic cap plugs when you
install the cable connectors.

2-6 Overview
SLE*-* Installation and Operation Manual PRELIMINARY - Motorola Internal Use Only
Power Supply
The SLE*-* power supply is a separate circuit board mounted in the lid of the housing and is
capable of 60 VAC or 90 VAC powering. The power supply provides a regulated 24 VDC output
over an AC input between 38 Vrms and 90 Vrms with a line frequency of 50 –60 Hz.
Figure 2-6 illustrates the SLE*-* power supply:
Figure 2-6
SLE*-* power supply
AC
GND
GND
+24V
The factory-installed 20-ampere fuse, illustrated in Figure 2-8, provides power-passing to
additional line extenders.
Forward Path
The minimum full gain of the SLE*-* is 35 dB or 40 dB depending on model. If you use the
SLE-BODE option, the operational gain of the SLE*-* amplifier is 28 dB or 32 dB (depending on
model) with 16 dB of return loss. If you use the SLE*-* in a system that may require Bode
equalization in the future, you should install a 7 dB JXP at the JXP-MID1 location (Figure 2-7)
between the input and output hybrid. The 7 dB JXP ensures that the appropriate operational
gain is used when the SLE-BODE is later installed.
The operating gain includes provisions for the insertion loss of the input cable equalizer and
required reserve gain to operate the Bode equalizer in the middle of its range. The low-noise
figure, pre-amplifier stage, is a conventional 870 MHz hybrid followed by a power-doubled
output stage. Between the two stages is a JXP-*B pad socket, the Bode board, and the flatness
and equalizer board. Because these losses are located interstage, the noise figure is only
significantly impacted by the insertion loss of the forward cable equalizer or broadband cable
simulator, and the input pad if its value is increased from zero.

Return Path
The circuit board of the SLE*-* accommodates the return path. This equips the SLE*-* to pass
signals in the return or upstream direction. The standard circuit board contains all components
including the diplex filters with extended return bandwidth for the amplifier input and output.
All items are plug-in and easily installed.
Optional SRE-*-* return equalizers compensate for cable attenuation and are available in 1 dB
increments for S-split, and 2 dB increments for all other splits, from 0 dB through 12 dB.
The input and output of the return path each include a JXP-*B pad facility. You can also use
either pad socket as a test point or a signal injection point. The return output pad value is
normally selected to control the return signal level into the next upstream amplifier. Select an
appropriate return input pad to attenuate excessive input signal.
The return-input test point and the return-output test point are −20 dB directional couplers.
Both test points present 75-ohm source impedance and do not require special test probes.

Ingress Control Switch
The ingress control switch (ICS) provides return-path signal attenuation or cutoff in the SLE*-*.
This is accomplished through the frequency-agile LIFELINE®status-monitoring module,
LL-SLE-HMS-*/*. (Figure 2-8 illustrates the location of the optional ICS). Please consult your
Motorola sales representative for the availability of LL-SLE-HMS-*/*.
To properly install the LL-SLE-HMS-*/*, the deeper housing cover (SLE-LID/SM is required.
The ICS provides a means of isolating sources of ingress from a centralized location. Using a
downstream command through the LIFELINE status-monitoring system, you can attenuate the
return path through the line extender by 6 dB or by 38 dB. By reducing the ingress level at the
headend or monitoring point, you can further isolate the ingress source.
After an ingress source is isolated to the last possible amplifier, node, or line extender, you can
shut the return path off at that location. This limits the impact of the ingress on the remainder
of the network while eliminating the source of ingress.
Options and Accessories
The factory ships the SLE*-* as a fully functional unit, but you must configure it appropriately
for the field-location requirements. You must install the correct forward equalizer or broadband
cable simulator and input pad to place the unit into service. Section 3, “Amplifier Setup,”
provides information to assist you in this task. Use model JXP-*B pads to control field signal
levels. To compensate for temperature, install the automatic drive unit (SLE-ADU) or thermal
drive unit (SLE-TDU) before placing the SLE*-* into service. You can install other items at your
discretion, but these options do not render the SLE*-* inoperative if they are not included.
Table 2-1 provides a comprehensive list of options and accessories for the SLE*-*:

SLE*-* options and accessories
Model Description Function
SLE-ADU-* Automatic Drive Unit This board automatically controls amplifier output levels
that change with cable attenuation and hybrid output.
The selection of a pilot frequency is required.
SLE-TDU Thermal Drive Unit This board controls amplifier gain and slope for
changes in cable attenuation for the sensed
temperature.
SFE-0, SFE-1 STARLINE Forward
Equalizer These equalizers are not bandwidth-specific and compensate for 0 dB and 1 dB of cable, respectively,
from 5 MHz to 1 GHz.
SFE-*-* STARLINE Forward
Equalizer This bandwidth-specific (750 MHz or 870 MHz) equalizer compensates for cable properties in 1 dB
increments from 2 dB through 22 dB. The appropriate
value must be installed. See the product catalog for
additional information.

Model Description Function
SRE-*-* STARLINE Return Equalizer This bandwidth-specific equalizer compensates for
cable attenuation in 1 dB increments from 0 dB through
12 dB for S-split (2 dB increments for all other splits).
The appropriate value must be installed. See the
product catalog for additional information.
SCS-* STARLINE Cable Simulator This simulator compensates for cable properties. The
appropriate value must be installed. See the product
catalog for additional information.
JXP-*B Fixed attenuator This pad attenuates excessive input signal. It is
available in 1 dB increments from 0 dB through 26 dB.
The appropriate value must be installed.
JXP-TH*C Thermal attenuators This option compensates for gain changes with
temperature in the return path.
LL-SLE-HMS-*/* Status monitor module This module enables monitoring of the unit’s operating
parameters by the LIFELINE status-monitoring system.
This accessory also requires the deep housing cover.
SLE-LID/SM Deep housing cover This optional cover is required to contain the LIFELINE
status monitor module.
RCB87 Response Correction Board This optional board compensates for system roll-off at
870 MHz. The SLE*-* is shipped with a jumper in this
location which you can replace when additional
response correction is required.
JXP-RPC Return Path Correction board This optional board provides additional flatness
response correction in the return path for systems that
must meet especially stringent return path flatness
requirements.
ICS-II Ingress Control Switch This option enables remote monitoring, isolation, and
reduction of ingress on the return path by providing
signal attenuation of 6 dB or cutoff of 38 dB typical. The
unit is shipped with a jumper in this location.
