3TX System Overview
Final assembly and test of each transmitter is performed at the Anywave factory.
The Exciter is setup on the desired channel frequency and the TX is tested with the
complete RF system (if purchased) at full power into a load. All TX operating
parameters are optimized and the Transmitter Forward, Reflected, and Reject load
power meters are properly calibrated. Linear and Nonlinear precorrection is performed
and automatically stored in non-volatile memory inside the Exciter. A Factory Test
Report is completed for each system, providing a record of full power operating
parameters and performance. The TX then goes through a final 24-hour burn-in period
and check out before being shut done and packed up for shipment.
In your shipment, you should receive a copy of the following documentation.

6RF System Connections
Once the TX cabinet is in position, the next step is to install the RF system and
connect the TX to the Antenna feed or a suitable station load before proceeding
further.
1. Mechanically mount BPF on top of TX cabinet
If you purchased an Anywave BPF, it is designed to be installed and mounted on
top of the 1KW TX cabinet (as shown below). Four metal stand-offs “feet” with
mounting hardware are supplied with the BPF to allow it to be fastened and secured
to four holes located in the top panel of the cabinet. Before securing the BPF with
the screws provided, please execute step 2 below, as you will need to be able to
move (slide) the BPF into place, and then apply the mounting screws.
1 –Mount BPF
2 –Connect Elbow and
Directional Couplers

ATSC 1KW TX Quick Start Guide
ACT-1000-QSG-DOC-V1.6, 9/12/2014 Page 12 of 23
2. Connect Elbow and Directional Couplers
With the BPF set on top of the cabinet, connect the 90º Elbow between the TX
output stack and the BPF Input (Before filter) Directional Coupler (as shown
above). Be sure that these connections are made properly and the RF bullets are
fully seated inside.
Connect the BPF Output (After filter) Directional Coupler to the BPF on one side
and then to the 1 5/8 slip-on flange adapter on the other side (not shown in photo
above) and then to your Antenna feed flange (please note: If your Antenna feed is
other than 1 5/8 EIA flanged, then you will need to provide whatever adapter
hardware necessary to facilitate this connection to your Antenna feed).
3. Connect Feedback sample cables
Connect the 2 x 20dB attenuators to the Before and After 50dB Directional
Couplers and then connect these attenuators to the Before andAfter filter feedback
BNC connectors located on the top of the cabinet with the cables provided (as
shown below). As a check, verify the Before and After samples are properly
connected to the respective inputs on the Exciter inside the cabinet.

7TS Input Stream Connection
With the RF output connections properly made, the next step is to connect your
19.39 MBPS TS input stream to the Exciter inside theTXcabinet. Usinga75ohm cable,
connect your ASI input stream to the TS IN 1 BNC connector on the rear panel of the
Exciter (as shown below). If you have more than one TS (multiple STLs, etc.) connect
your redundant TS input to the TS IN 2 BNC connector.
Please note: The above instructions apply to the 5X Exciter (which requires an ASI
input signal) and is most likely the Exciter installed in your system. However, if you
ordered the 9X Exciter (that can accept an ASI, SMPTE301M, or TSoIP (optional) TS
input, the rear panel connections on your Exciter will look slightly different. Please
consult your 9X User Manual for details.
With a valid ASITS stream connected to the TS IN 1 and/or TS IN 2 on the Exciter,
verify that the corresponding TS1 and/or TS2 Led is illuminated on the front panel of
the Exciter as shown below.
Please note: The Exciter SysErr LED illuminates solid RED when the Exciter is in
Local mode and is OFF when the Exciter is in Remote mode. This LED only indicates
a SysErr when flashing.

8AC Mains Connections
Please review the safety WARNINGS on page 4 of this manual before proceeding
with any electrical work.
A licensed Electrician is required to properly and safely connect the 220V power
cable from your stations electrical panel to the terminal block located inside the TX AC
Mains Distribution compartment in compliance with local electrical and building codes.
Please note: a power cable is not provided with the Transmitter system and should be
obtained via your local Electrician.
Be sure the Main Breaker on the lower left front of the TX is turned OFF before
performing any electrical work on the TX (as shown below).
Main Breaker OFF

Electrical Requirements
The 1KW ATSC Transmitter cabinet is wired for 220V single-phase power to be
sourced from a 30A breaker. A 3-wire gauge10 cable is recommended to make the
connection between the TX AC Mains Distribution terminal block and the 2-pole 30A
breaker in the facility electrical panel. Please note: this cable is not provided with your
Transmitter equipment and should be obtained from your local Electrician.
.
Properly connect the three wires to the terminal block as outlined in the above
diagram, taking care to notice which terminal is connected to the chassis Ground in
your system. Earlier systems (prior to the addition of the EMERGENCY Stop button –
located on the upper right front of the cabinet) are wired L1, GND, L2, while newer
systems are wired L1, L2, GND (as shown in the above diagram). Be sure to connect
the GND terminal properly and other two connections as L1 and L2.
L1, L2, GND wires from
30A breaker connect to
terminal block here (Be sure
to connect GND to proper
terminal in your system)

9Initial Turn On
Once the RF connections have been properly made into your antenna feed or
suitable station load, and the Transmitter has been properly wired to the station
electrical panel (as outlined in sections 6 & 8) you are now ready to turn on the
system.
Please locate and have handy for reference a copy of your 1KW TX Factory Test
Report as well as the 1KW TX Quick Start Guide, and TX and Exciter User
Manuals.
Please follow the steps outlined below to safely turn on and bring your TX
system up to power.
1. Apply power to the Transmitter by turning ON the AC Main Breaker
located in the lower left front of the TX and ensure that the AC Mains
indication is illuminated. You will hear the PA fans rev up to full speed for
a few seconds and then ramp down.

It takes about 5 seconds for the Controller to power up and display the
HOME screen (shown below). Please note that the values will be different
as the TX initially turns ON at a reduced power level.
The Controller HOME touchscreen display will indicate System Forward
(FWD), Reflected (REFL), and Reject Load (REJT) output power in Watts
in real time.
2. Check Exciter settings. Check the operating Frequency of the Exciter by
navigating to the Exciter FREQ submenu (simultaneously press Left and
Right buttons)
Check the Exciter drive level is set to -25dBm by navigating to the Exciter
RF submenu (from above, press ESC button then enter the RF submenu).

3. You are now ready to bring the TX up to power. To accomplish this, slowly
increase the drive level out of theExciter byincreasing the POWER setting
in the Exciter RF submenu while watching the Sys FWD power increase
accordingly on the Controller touchscreen.
Begin to slowly raise the FWD System power by using the UP button on
the Exciter, while monitoring the FWD system power meter on the
Controller HOME screen as shown below.
4. Slowly bring the FWD power to ~500W (half-power) and notice the power
meter values of REFL, REJCT, and VSWR to be sure these look reasonable
(less than a 1KWTX operating at a full 1000W FWD that has typical REFL,
REJT, and VSWR as shown above).
Check to be sure that the lower left corner of the HOME screen shows the
status as “RUNNING OK!” and there are no error messages. If you do see
an error message, please reference the Troubleshooting section of your
transmitter User Manual to understand what the error means and suggested
steps to correct it. (For example, when initially turning on a system, on
occasion the error message AMP_VSWR_ERR (accompanied by high
REFL power readings) has been witnessed - indicating a connection
problem somewhere in the external RF System –a mismatch sending hi
reflected energy back to the REFLsample on the output directional coupler
inside the TX cabinet.)

5. Continue to slowly raise the FWD power until you reach the full 1000W,
or your desired TPO. Be careful to make small increases in the value of
POWER as you approach the desired output level.
6. Check the SNR and Shoulder (LIMD and UIMD) RF performance of your
system by pressing the Exciter Aicon on the Controller HOME screen (or
on the Exciter hi level status screen) as shown below.
Linear and Non-Linear corrections were already performed and optimized
at a TPO of 1000W in the factory and so the stored correction coefficients
should produce good results.
If you are operating at a TPO less than 1KW or wish to rerun corrections,
please reference the “Running Corrections” section of your transmitter
User Manual.
7. With your TX operating at your desired output power and with good RF
performance, the next step is to setup and engage the TX AGC. Continue
to slowly raise the output power of the system to 1.1 x desired TPO (for
example 1100W if a 1000W TPO level is desired). (Note: You are bringing
up the TX to 1.1 x desired TPO to provide 10% headroom for AGC
operation).

ACT-1000-QSG-DOC-V1.6, 9/12/2014 Page 20 of 23
8. Navigate to the AGC screen on the Controller (by pressing the CONFIG
button and then the AGC button). Be sure the AGC Target FWD power is
set to 1000W, or whatever TPO level is desired for operation, and then
press the unlit AGC button to engage the TX AGC and turn this button
Green.
9. Press the HOME button to return to the HOME screen to monitor FWD
power as it slowly reduces from 1.1 x TPO to the AGC target power
(desired TPO) level over the next minute or so. With the AGC engaged,
the FWD power metering may vary up to +/- 5%, so for a 1000W TX,
meter variations from 950W to 1050W may be experienced.
