WARNING
Amplifier Cooling
ln orderlo gain access to the various circuits in the TSA50HSS Amplifier,
it is necessary to remove the drawer cover. Please be advised that this
cover is an integral part of the drawer cooling and may not be removed
for more than five minutes while the amplifier is in operation. Any period
longer than this could cause overheating and catastrophic damage to the
final amplifier.
IMPORTANT
Transient Overvoltage Protection
Transient overvoltage of micro- and nano—seconds durations are a
continuous threat to all solid-state circuitry. The resulting costs of both
equipment repairs and system downtime make preventative protection
the best insurance against these sudden surges. Types of protection
range from isolation transformers and uninten'uptible power supplies to
the more cost effective AC power line protectors. As transient culprits
are most often lightning induction and switching surges, AC power line
protectors are the most practical solution. An effective AC power line
protector is one capable of dissipating impulse energy at a low enough
voltage to ensure the safety of the electronic components it is protecting.
The protection unit should be across the AC line at a_|l times even during
periods of total blackout. it should also reset Immediately and auto-
maticaliy to be 100% ready for repeated transients.

1.3 Installation:
NOTE: The connectors mentioned in the following instructions are located on the rear of the
equipment.
1. After unpacking the TSA5DHSS, a thorough inspection should be conducted to reveal any
damage which may have occurred during shipment. If damage is found. immediately notify
the shipping agency and advise EMCEE Broadcast Products (Customer Service) or its field
representative, Aiso check to see that any connectors, cables or miscellaneous equipment,
which may have been ordered separately, are included.
2. Place the TSASOHSS in a clean, weatherproof envimnment providing adequate ventilation
for the exhaust fans at the rear of the drawer. it is important to maintain the amplifier’s
ambient temperature within the 730°C and +50°C limits.
3. Place the TSASDHSS in its permanent location near a receptacle that supplies 115Vac at
50/60Hz. Unless the customer has specifically requested a power requirement of 230Vac at
SOIGOHZ, the TSASOHSS will operate only from a115Vac source. The ac source should have
a minimum power capacity of 600W plus the power requirements of any other drawers
operating from that source.
IMPORTANT
Do not apply ac power to the amplifier at this time since its RF output must be
property loaded before being placed in operation.
4. Set all circuit breakers and switches, including the customer‘s incoming line breaker, to the
OFF position. Place an appropriate ac power line protector (surge suppressor) across the ac
line that supplies the amplifier.

Connect the transmitting antenna/channel combiner cable to the TSASOHSS RF OUT
connector (J3).
If the TSASOHSS is packaged in a cabinet with an appropriate EMCEE driver (eg., a
TTStOHSX with a split output), proceed to step its: otherwise, continue with step 116.
Fasten a low—loss N to N cable to the driver's VISUAL RF OUT connector (J3 on the
Tl'S10HSX with a split output) and the TSASUHSS VISUAL RF lN connector (J1). Fasten
another low-loss N to N cable to the driver‘s AURAL RF OUT connector (J5 on the
TTS10HSXwi1h a Split output) and the TSA50HSS AURAL RF IN connector (JZ).
Locate the small-wire hamess with the two Q-pin female connectors supplied by EMCEE
(accessories box). Fasten one end of this harness to the driver's CONTROL connector (J4
on the 1'I'810HSX) and fasten the other end to the TSASOHSS CONTROL connector (J4).
If a driver other than the TTStDHSX/TTStOHSB/TTSWEB is used, pin 1 of the
TSASOHSS CONTROL connector (J4) must be provided +15Vdc to activate the
amplifier. When the TSAEOHSS interlock circuit is closed, +12Vdc switched is applied
to the amplifier module as well as to pin 2 of its CONTROL connector (see Figure 2-1).
This voltage should be used to initiate RF drive from the driver, eliminating the
possibility of damage caused by prematuretydriving the TSASOHSS before bias voltage
is applied to its amplifier modules.
Plug the power cord of the TSASOHSS into an appropriate electrical outlet.
Verify that the wire harness and RF cables are connected properly. Verify that the power
cords of the TSASDHSS and its driver are plugged into the receptacle at the bottom of the
system's cabinet.
Plug the power cord of the system's cabinet receptacle into an appropriate electrical outlet

d. The SYNTH LOCK indicator oi the TTS10HSX should be illuminated green.
For the TTS1OHSX and TSASOHSS, place their corresponding OPERATE/STANDBY
switches to OPERATE. Then verify the following responses of the system. (NOTE: The
Tl'Si OHSX °/n POWER meterwill not read 100% when the TSAEDHSS is at 10090, Typically
the transmitters % POWER meter will be approximately 60%.)
a. The OPERATE/STANDBY indicators of the Tl'S10HSX and TSASOHSS should be
illuminated green.
b. The VSWR OVLD indicators of the TTS1OHSX and TSASDHSS should remain
extinguished.
c. The SYNTH LOCK indicator oi the TI'StOHSX should remain illuminated green.
(1. The AURAL DRIVER, AURAL FINAL, VISUAL DRIVER, and VISUAL FINAL indicators
ofthe TTS10HSX should be illuminated green as well as the AMPL A1 indicator of the
TSASOHSS.
Place the TSASOHSS meter switch to VlS and tum the TTS10HSX VISUAL POWER ADJ
control clockwise until a 100% indication appears on the TSASOHSS °ln POWER meter.
Place the TTS1OHSX AGC switch to ON.
8. Verify that the TSASOHSS % POWER meter still reads 100%. If necessary, vary the
TI'S1UHSX AGC ADJ control for a 100% indication.
b. Verify that the 17510st AGC indicator is illuminated green.
Place the ‘l‘l’SiDHSX meter switch to AURAL and turn its AURAL POWER ADJ control
clockwise until a 100% indication appears on its % POWER meter.
Place the TSA50HSS meter switch to REFLECTED and verify that its % POWER meter
indicates no more than 10% returned power. If the reflected power is more than 10%, shut
down the system and check the VSWR oi the transmitting antenna and its associated cable.
Place the TSASOHSS meter switch to VISUAL for constant monitoring of the system's visual
output power.
The TSA50HSS Power Amplifier driven by the TTS10HSX Transmitter is now in operation. Check
the system's coverage area for clean, sharp television reception. If the reception or picture quality
is unsatisfactory, examine the amount of power delivered to the transmitting antenna (see
section 3.4) and, if necessary, examine the antenna orientation, antenna VSWR. and transmission
line VSWR to insure maximum radiation in the proper direction.

REFLD POWER Coupling (J2-J4) 30dB
AURAL SAMPLE Coupling (J7—JG) 30GB
The Combiner Coupler (A3) is a seven-port module which performs two functions. The first
function is to combine the amplified visual and aural S-Band carriers applied to ports J1 and J7,
respectively. The combined carriers result in a composite signal at port J2 where the aural carrier
is attenuated by todB. This signal is applied to the amplifiers rear panel VISIAUR RF OUT
connector. A sample of the composite signal is coupled to port Ja where it is then applied to the
amplifier's front panel RF SAMPLE connector. The second function is to provide a sample of three
RF signals which are used by the Metering Detector (A2). These RF signals include a sample of
the forward visual carrier at port J5, a sample of the forward aural carrier at port Jo, and a sample
of the reflected visual signal at port J4.
Metering Detector:
Schematic Diagram 30368024/Rev P a A1A2
The Metering Detector (A2) contains separate but similar circuitry for monitoring the peak visual,
average aural. and average reflected power at the output of the amplifier. Samples of these three
RF signals are supplied via the Combiner Couplerr
The front end or detector portion of each circuit is basically the same. Diodes CR2, CR3, and CR4,
together with theirsurrounding components, convertthe sampled on-channel RF signals to positive

is accomplished by CR2 in conjunction with R4 and C2 which form a time constant oft second.
R4 is the dc load white 01. C11 and C17 form the RF ground of the visual power detector.
Detection of the other two sampled RF signals is the same except for a faster time constant
(RZZICG) in the reflected power detector. The positive do voltages from the visual, aural, and
reflected power detectors are processed by buffer amplifiers U1 and U2 which provide voltage
gains of 1VN and 2VN. respectively. These buffer amplifiers also provide isolation between the
% POWER meter (M1) and the detectors, The setting of potentiometers R9, R18. and R27
determines the voltage level applied to the % POWER meter when the meter switch (P0381) is
in its VIS, AUR, and REFL positions.
A dc voltage proportional to the amplifier’s visual output power is applied to pin 5 of connector J4.
designated VISUAL POWER REFERENCE. When using an EMCEE HS series transmitter as a
driver, this voltage is fed back to the IF/Upconverter (A8) of the transmitter, When the AGC snitch
(PC283) is in its ON position, this voltage ultimately controlsthe attenuation of the visual lF carrier
so that the amplifier‘s visual output power is automatically maintained close to its rated value.
A dc voltage proportional to the transmitters reflected output power is fed to pin 10 of comparator
U2, This voltage is compared to a reference voltage at pin 9 whose magnitude is determined by
the setting of potentiometer R30. Vlfith R30 properly set (see paragraph 3.5b), the voltage on
pin 10 will be greater than the reference voltage whenever the transmitters reflected power is at
least 50% of its rated forward power. As a result, the output of the comparator saturates in the
positive mode applying approximately +4Vdc to pin 7 of connector J-t, designated VSWR OVLD.
This voltage instructs the Monitor/Control (P01) that a VSWR overload condition has been
detected. However, when the transmitters reflected power Is less than 50% of its rated forward
power, the voltage on pin 10 of comparator U2 will be less than the reference voltage. As a result.
the comparator saturates in the negative mode, diode CR1 is forward biased, and approximately
—D.7Vdc is applied to pin 7 of connector M. This voltage instructs the Monitor/Control that no
VSWR overload condition exists.
MonitorIControI:
Schematic Diagram 3039007D/Rev 52 it A1F‘Ct
The Monitor/Control hoard (P01) provides various monitoring and control functionsforthe amplifier
while displaying the results on several front panel diagnostic indicators, The circuitry ofthis board
can be divided into three sections:
(1) Interlock Monitoring/Display Section
(2) Fault Monitoring/Display Section
(3) Miscellaneous Control/Display Section
The interlock monitoring/disglay section monitors several key voltages and displays the results on
the OPERATE/STANDBY (DS1) and VSWR OVLD (D53) indicators. The voltages monitored
include the Metering Detectors VSWR OVLD voltage. the x15Vl+5V Power Supply's -15Vdc and
+5Vdc voltages, and the lNTLK RETURN voltage. When these voltages are at their normal levels
and the OPERATE/STANDBY switch (81) is in its OPERATE position, the amplifiers interlock
circuit is closed and in the operate mode. In this mode, the VSWR OVLD indicator is extinguished
while the OPERATE/STANDBY indicator is illuminated green. However, if one or more of these
voltages significantly deviate from their normal levels, the interlock circuit is automatically opened
placing the unit in the standby mode with the OPERATE/STANDBY indicator illuminated orange.
2—3
The Metering Detectors VSWR OVLD voltage is normally 70.7Vdci On the Control/Monitor board
this voltage is buffered by exclusive-OR U5 and applied to the clock input (pin 11) of flip-flop U2
whose Q output (pin 9) is normally high. U2‘s 0 output changes stale whenever its clock input
goes positive. Therefore, when a VSWR overload condition is sensed by the Metering Detector
(A8), the VSWR OVLD voltage switches from 70.7Vdc to about +4Vdc causing U2's 0 output to
toggle low. This low is sensed by pin 5 ofAND gate U1 placing the transmitter in its standby mode.
This low is also sensed by the base of Q4 which causes Q4 to tum off and the VSWR OVLD
indicatorto illuminate red. U2‘s Q output can be reset high by activating the VSWR OVLD RESET
momentary switch (82).
To insure proper bias is applied to the amplifier transistors. the Monitor/Control board also
examines the 715Vdc portion of power supply P82. When the 715Vdc voltage is present, zener
diode VR1 is biased in its breakdown region while diode CR1 is forward biased clamping the base
of 03 at —0,7Vdc. With 03 normally tumed off, a high is applied to pin 4 of U1‘ However, when
-15Vdc is no longer available, VR1 and CR1 are turned offwhile 03 is turned on applying a low
to pin 4 of Ute This low results in placing the amplifier in its standby mode.
Another condition necessary to allowthe transmitter to operate is that the INTLK RETURN voltage
is present and the OPERATE/STANDBY switch is in its OPERATE position. In this configuration
a high is normally applied to pin 12 of U1t However, when the INTLK RETURN voltage is no
longer available, a low is applied to pin 12 of U1 placing the amplifier in standby. The INTLK
RETURN voltage will be the +15Vdc supplied by the transmitter driving the amplifier to pin 1 of
CONTROL plug J4 on the amplifiers rear panel. This is accomplished using the appropriate wire
harness connected between CONTROL jack J4 of the TSASOHSS amplifier and CONTROLjack
J4 of the HS series transmitter/driver. Also, the thermostat attached to amplifier A1 must remain
closed below temperatures of 175°F.
Under normal operation, the above conditions will be met and output pin 3 of AND gate U1 will be
high, forward biasing transistors 05 and 06. The ground provided by 06 via J1-22 activates
oontactor K1 which in turn supplies 12Vdcto the sow S-Band PowerAmplifier Module placing the
transmitter in operation. The high placed on J1-12 from the activated contactor forward biases
transistor Q1. extinguishing the red portion of OPERATE/STANDBY LED DS1 tuming it green.
Conversely, if one of the monitored voltages mentioned above changes state, pin 3 of U1 thl
switch low turning off transistors 05 and 06. This will result in the removal of the switched 12Vdc
from the flow S-Band amplifier due to the deactivation of contactor K1. Also, with loss of the
switched 12Vdc, transistor Q1 will be reverse biased via J1-12 turning the OPERATE/STANDBY
LED to orange.
The fault monitoring/display section monitors the detection of a failure associated with the four
transistors in the 50W S—Band Amplifier (A1) and displays the result on the AMPL A1 front panel
indicator. Under normal operation, the voltage level on the amplifier FAULT line is low (0.4Vdc).
if a fault is detected in the sow S—Band Amplifier, the conesponding FAULT line becomes high
(+4Vdc). This high is applied to transistor 08. The conesponding low at its collector results in
forward biasing series diode CR4 which extinguishes the green LED of the associated indicator
D89. Meanwhile. the low on the collector of Q8 results in reverse biasing transistor Q7,
illuminating the red LED of the fault indicator.

Troubleshooting:
If the visual and/or aural output signals from the TSASOHSS appear distorted, noisy or nonexistent.
consider the following procedure as a troubleshooting aid. tNOTE: Th‘s procedure assumes the
cabling and connectors are trouble free. It also assumes the TSASOHSS is driven by a proper input
signal.)
1. The general problem area may be pointed to by simply checking the TSASOHSS front panel
diagnostic indicators as well as the % POWER meter and the signal seen at the RF SAMPLE
port. The diagnostic indicators are located on the amplifiers front panel.
a.
The OPERATE/STANDBY indicator illuminates green whenthe following conditions are
sat’sfied. The AC POWER circu‘n breaker “5 closed, the drivers INTLKI+15V voltage is
available, the 175°F thermostat is closed, the OPERATE/STANDBY switch is in its
OPERATE position, a VSWR overload condition does not ex'st, the t15V/+5V Power
Supply‘s ~15Vdc and +5Vdc voltages are available, and the contactor is energized
supplying +12Vdc switched. However. if one or more of these conditions are not
satisfied. the OPERATE/STANDBY indicator illuminates orange indicating the
TSASOHSS is in its standby or nonradi rng mode with us interlock circuit open (see
Figure 2-1).
The VSWR OVLD indicator is normally extinguished. However, this indicator illuminates
red when a VSWR overload condition exists.
Assuming +12Vdc switched and 715Vdc are avaiable,theAMPLA1 indicatorilluminates
green when the RFtransistors ofthe amplifier module are operating correctly. However,
ifone of these transistors fails. the corresponding indicator will illuminate red.
The % POWER meter, in conjunction with the meterswitch, provides an indication of the
voltage from the +12V Power Supply aswell as an indication ofthe peak visual, average
aural and average reflected power at the output of me TSASOHSS.
The RF SAMPLE port provides convenient monitoring of the TSASOHSS sampled
composite output signal. The signal applied to the RF SAMPLE port is approximately
40dB less than the power level of the signal that is sampled.
2. The problem area can be specifically determined by systematically troubleshooting the
circuitry comprising the various sections of the TSASOHSS.
a.
The TSASDHSS can be subdivided into four sections:
(1) Power Supply/Circuitry (C81, E1, P51, P82, K1)
(2) RF Amplifier Chain (A1, A3)
(3) Power Detection/Metering circuitry (AT1, AT2, AT3, A2, P02, M1)
(4) Diagnostic/Control Circuitry (P01, A1 S1)
Verify that the power supply/circuitry is not at fault.
Verit'ythe specified gain or loss of each module comprising the RF amplifier chain. With
the TSASOHSS RF OUT portterminated in 50 ohms, set upthe test equipment as shown
in Figure 3—1 and use the signal flow diagram provided in Figure 3—2.

d. Verify that the powerdetection/metering circuitry and the diagnostic/control circuitry are
not at fault.

The following chart is meanl as an aid to uncovering faults that have developed in this amplifier.
During normal operation, all indicator LEDs are green, except the VSWR OVLD LED which is
normally extinguished. This chart l'sts the LEDs that are indicating a fault (Le. are not in their normal
state). if a problem develops with the amplifier, note the state of the indicatorLEDs and compare this

In order to gain access to the various oircufls in the TSASOHSS Amplifier, it is
necessaryto remove the drawercover. Please be advised thatthis cover "5 an integral
pan of the drawer cooling and may not be removed for more than five minutes while
the amplifier is in operation. Any period Iongerthan this could cause overheating and
catastrophic damage to the amplifier module.
50 Watt Transmitter (TTS10HSX with Split Output and TSASOHSS):
To insure correct transmission parameters, the output power level and % POWER metercalibration
oi the TSASOHSS driven by the TTS10HSX should be checked at least once every year. Win the
TSA50HSS meter switch in the VISUAL position, its % POWER meter has been factorycalibrated for
100"/o with the TSASOHSS providing 50W peak visual power. Wth the meter swnch in the AURAL
position, its % POWER meter has been factory calibrated for 100% with the TSASOHSS providing
1.25W average aural. The following calibration procedure assumes that the composite signal from
the transmitterhas a visual/aural carrier power ratio ol40:1 with the visual carrier consisting of87.5%
video modulation and 0% average picture level (APL), When measuring these power levels as shown
in Figure 3—3, be sure to take into account the 30dB attenuation factor provided by the attenuator.
Power levels at 50% APL are included in brackets toilowing the power levels at o% APL.
1.
Place the TSASDHSS OPERATE/STANDBY switch to STANDBY and set up the test
equipment as shown in Figure &3.
For the TTS10HSX modulator, place its power switch to ON (if applicable) and verify that it
provides 87,571: video modulation, Forthe ‘l'l's10HSX UpeonverterlPower Amplifier drawer,
place its AC POWER circuit breakerto ON, its AGC switch to OFF, its OPERATE/STANDBY
switch to OPERATE. and turn its AURAL POWER ADJ control fully counterclockwise to
disable the aural can'ier. Forthe TSASDHSS. place fls AC POWER circu't breakerto ON and
Rs OP ERATE/STANDBY switch to OPERATE.
To set the TSASOHSS visual output power, adjust the TTS10HSX VlSUAL POWER ADJ
control fora power meter reading ot29.8W[17.0W]. (Note that 50W peak visual with 0% APL
and 87.5% video modulation is equal to 29.8W average visual.)
Afler a 15-minute warm-up, place the TSASOHSS meter sw‘tch to VISUAL and check its
% POWER meter for a 1009-1 indication. (Note that the ‘l'l'SloHSX visual % POWER meter
will not read 100%. It typically will read appron'mately 60%.) If this reading is not obtained,
adjust potentiometer R9 of the TSASOHSS Metering Detector for a 100% indication, The
Metenng Detector is mounted to the right-hand inside wall of the TSASDHSS PowerAmplifier
drawer.
Place the TTSl OHSX AGC switch to ON and vet'it’ythat the TSASOHSS % POWER meter still
reads 10096. If necessary, vary the TI'S10HSX AGC ADJ control for a 100% indication.
To set the TSASDHSS aural output power, adjust the TTSlOHSX AURAL POWER ADJ
control for a power meter reading of 31 .1W[18.25W|. (Note that »16dB aural power is equal
to 1.25W average aural; therefore, 29.8W average visual plus 2.5% aural power is equal to
31 .1 W average.)
Place the TSASOHSS meter sw'nch to AURAL and check its % POWER meter for a 100%
indication. If this reading is notobtained, adjust potentiometer R18 of the TSASOHSS Metering
Detectorfor a 1 00% indication. The Metenng Detector is mounted to the right-hand inside wall
of the amplifier drawer.

Place the TTS10HSX AGC switch to OFF and then adjust potentiometer R30 of the
TSA50HSS Metering Detector iuIIy clockwise to disable the VSWR overload detection circuit.
Remove and reverse the coaxial cables connected to the two 10dB attenuators which in turn
are connected to the VlS sample (J1) and REFLsampIe (J3) ports ofthe TSASOHSS Metering
Detector. The reflected power circun of the TSASOHSS Metering Detector will now monitor
the system's forward power, simulating an open circuit (total returned power) at the system's
output.
Place the TSASOHSS meter switch to REFL and check its % POWER meter for a 100%
indication (70% for 50% AF‘L). If this reading is not obtained, adjust potentiometer R27 of the
TSASOHSS Metering Detector forthe correct indication,
Decrease by 50% the TSASOHSS output power by setting the TTS10HSX VISUAL POWER
ADJ l’ora power meter reading of 1 5.6W [9.1Wj. This average power level is used for setting
the “trip point" of the TSASUHSS VSWR overload detection circuit. Adjust potentiometer R30
of the TSAsOHSS Metenng Detector slowly counterclockwise until its VSWR OVLD indicator
illuminates red. Leave the potentiometer at this setting.
Remove the coaxial cables connected to the two 10dB attenuators and connect them to their
original positions. Since 50% reflected power is no longer present, reset the TSASOHSS
VSWR overload detection circuit by activating its VSWR OVLD RESET momentary switch.
Verify that the TSA50HSS VSWR OVLD indicator extinguishes.
Increase the TSASOHSS output power from 50% back to 100% by resetting the 17310st
VISUAL POWER ADJ. Keep the TSASDHSS meter switch to VIS for constant monitoring of
the system's visual output power. Place the TTSl OHSX AGC swnch to ON and, if necessary,
set the AGC ADJ for a 100% indication on the TSASOHSS % POWER meter.
Place the TSASOHSS OPERATE/STANDBY switch to STANDBY. Reinstall the top covers to
me TTS10HSX Upconverter/Power Amplifier drawer and the TSASOHSS Power Amplifier
drawer, slide the drawers back into the cabinet, and secure them properly, Disconnect the test
equipment (mm the system. Reconnectthetransmitting antenna cable to the TSASOHSS RF
OUT connector (JZ).
Place the TSASUHSS OPERATE/STANDBY sw‘nch to OPERATE to place the system on the
air.
