Your TXRX Systems Inc. Tower Top Amplifier Sys­tem provides the highest degree of reliability avail­able in a Tower Top Amplifier (TTA). The system
uses quadrature-coupled amplifiers (also called
balanced amplifiers) to create a redundant ampli­fier configuration in both the tower box and the
receiver multicoupling unit (MCU). Each quad­amplifier provides two simultaneously used, essen­tially parallel paths of amplification. Failure of one
of these paths of amplification results in an overall
gain reduction of only 6 dB.

The system also supplies automatic backup-ampli­fier switching in the tower top box. Fault detection
circuitry continuously monitors the DC power oper­ation of the primary quad-amplifier and automati­cally switches to the identical secondary quad­amplifier if conditions indicate a primary malfunc­tion. If the secondary quad-amplifier malfunctions,
operation switches to whichever quad-amplifier is
still providing some gain due to operation of one of
its amplification paths. Fault detection circuitry also

provides at-a-glance status reporting, with front­panel LED ’s a nd an LCD displ ay. The sy stem
specifications for the tower top amplifier are listed
in Table 1.

the weak received signal before the signal enters a
long and lossy transmission line, thus preventing
the line loss from degrading the signal-to-noise
ratio. The quadrature amplifiers have a separate
power circuit for each half of the amplifier which
provides component redundancy as well as unsur­passed IM performance. Microprocessor controlled
fault detection circuitry in the tower top box pro­vides continuous monitoring and switching of each
quad amplifier while sending operational data to
the base unit front panel for at-a-glance status
reporting and form-C contact switching for alarm
integration. Included in the tower top box is a pre-

specifications for the MCU are listed in Table 3.
Also included in the system is a webpage user
interface for controlling and monitoring of amplifier
currents, alarms, and attenuators. The webpage
user interface is accessed through the front panel
LAN connector. Refer to Appendix A for instruc­tions on accessing this feature.

PRE-INSTALLATION CHECKOUT

The following pre-installation tests should be per­formed after unpacking the system to verify nothing
has loosened during transit. Additionally, the sys­tem should be made operational on the bench with
all components at ground level to verify proper
electrical performance. Figure 3 illustrates all of
the cable connection points for both the tower top
box and the MCU.

UNPACKING

Each major component of the TTA system is indi­vidually packaged and shipped via motor freight or
UPS. It is important to report any visible damage to
the carrier immediately. It is the customer's respon­sibility to file damage claims with the carrier within
a short period of time after delivery (1 to 5 days).

The tower top box should NOT be
installed on the tower until all of the
pre-installation tests are successfully
completed.

Mechanical Inspection

Open the tower top box by loosening all the door­clamp locking screws and rotating the clamps to

tors are tight. In addition, it is advisable to check
the tightness of the hold-down screws for the vari­ous assemblies to insure nothing loosened during
shipment. Likewise, check all of the cable connec­tions on the MCU to insure they are all properly
mated to their associated plugs.

Initial Power-Up Test

To perform the initial power-up test the system
should be temporarily interconnected at ground
level using short cables. Figure 4 shows the tem-

porary equipment hookup for initial power-up test­ing.

Once the equipment is temporarily interconnected
then power is applied to the system by plugging the
MCU’s AC cord into a suitable AC outlet (model
429-83H-01-M) or connecting the DC power cable
to a suitable -48 VDC supply (model 429-83H-01­M-48). The following start-up sequence occurs.

1) At turn-on, the three front panel status LED’s
will all glow a steady red while the display panel
shows a row of solid boxes on the top display
line. This will last for about 10 seconds while
the systems micro-controllers boot-up.

2) During the next 5 seconds the base unit (MCU)
will establish communications with the tower
box. The front panel status LED’s will occasion­ally flash green. The display panel will present
the message “Connecting to Tower Controller”
and then will briefly flash the MCU’s current
software version. See Figure 5.

3) After the power-up sequencing is complete the

screen should show the default display as
shown in Figure 6. The status LED for each
active amplifier will glow a steady green and the
status LED for the inactive (stand-by) LNA will

The tower top amplifier system is software directed
so control of the system is accomplished via user
interface with the front panel using the display
screen and the four menu selection buttons. A flow
chart showing all of the possible user menu selec­tions is shown in Figure 7.

Bench Testing

The purpose of the bench test is to verify that all of
the system components are working correctly and
to measure the systems sensitivity before climbing
the tower to mount the tower top box. One station
receiver is selected and the test is performed at
this frequency. Short temporary cables are used to
interconnect all components. A SINAD meter is
used for the test (or a bit e r r o r rate m et e r if
required) along with a signal generator.

1) The stand-alone receiver sensitivity is mea­sured and recorded first. Record the value in
Table 4.

2) Connect the equipment as shown in Figure 8.
Be sure that the signal generator is setup for a 3
KHz deviation with a 1000 Hz tone (analog) or
proper pattern for BER testing.

3) Measure and record the systems bench test
static sensitivity in table 4. The sensitivity value
will vary depending on the amount of internal
programmable attenuation selected via soft­ware interface. The bench test measurement
should be taken with the default values selected
for “TTA NET GAIN” attenuation (3.0 dB) and
“DISTRIBUTION” attenuation (1.0 dB). These
are the factory default settings that are pro­grammed into your system when you first turn it
on.

4) Select the other tower top amplifier and check
that the bench test static sensitivity value
remains nearly the same. This will insure that
both amplifiers in the tower top box are func­tioning properly. To select an alternate tower­top amplifier press the associated amplifier
select button on the front panel, the status LED
will begin to flash, then press the ENTER button
to finalize the selection.

5) If the tower box door is opened during the
installation it is important to re-tighten the door­clamp locking screws uniformly so that the door
gasket seal is maintained. Tighten each clamp
about half-way, then start back at the first clamp
and fully tighten each one in the same order.
Tighten with a hand tool only. Insure that the
moisture vent holes at the bottom of the box are
unobstructed.
