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 and Reflected 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.
- Packing Checklist
- Transmitter Factory Test Report
- 280W TX Quick Start Guide
- 280W PA and Exciter User Manuals
Carefully unpack and inspect all your equipment and please review the Packing
Checklist when you receive your systemto be certain you have received all your system
components. Also, please be sure to identify and remove all packing materials and
supports (foam pads, etc.) prior to initial turn on of the equipment.
All Single PA TX systems ship with an AC power cord included with the Exciter
and PA. The PA shipment also includes an RS232 cable, for Exciter to PA
communications, and a CAT5 Ethernet cable, for Exciter to PC built-in web interface
Remote Monitoring and Control.

4TX System Interconnect
The Anywave ATSC 280W DTV Transmitter consists of an Exciter, a controller with
touchscreen, 280W PA, and a BPF (optional) with two additional single port couplers for
Exciter feedback samples (optional). The diagram below shows the overall system
interconnect between the system components.

5Initial Turn On
Please locate and have handy for reference a copy of your 280W TX Factory Test
Report as well as the 280W TX Quick Start Guide, and 280W PA and Exciter
User Manuals.
1. With all equipment turned OFF, please make the cable connections according
to the System Interconnect Diagram of section 4. Make sure the BPF or PA
output is properly connected to your Antenna feed or a suitable station load
before proceeding further.
2. Turn ON the Exciter via its rear panel AC switch.
3. 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).
(Please refer to your Exciter User Manual for help with detailed operation of
the Exciter).
4. Turn the 280W PA ON via the PA rear panel breaker, then press the front panel
PARF On/Off button to turn ON the PA - which should turn BLUE when ON.
5. The built-in FWD and REF power metering in your 280W TX has already been
calibrated at the factory. The Exciter PAC submenu contains the System
Forward and Reflected power meter readings PA_Fwd and PA_Ref. Visit the
PAC menu on the Exciter LCD (under Advanced submenu) or Web interface

ATSC 280W TX Quick Start Guide
ACT-280-QSG-DOC-V1.2, 07/12/2018 Page 10 of 13
and verify that the voltages (Vol_9 and Vol_50) and current (Cur1_50, Cur2_50)
are showing real values and not all 0s.
6. You are now ready to bring the TX up to power. To accomplish this, slowly
increase the drive level out of the Exciter by increasing the POWER setting in
the Exciter RF submenu while watching the PA_Fwd power increase
accordingly on the PAC submenu (you will need to navigate between the Exciter
RF and PAC submenus).
Begin to slowly raise the FWD System power by using the UP button on
the Exciter, while monitoring the PA_Fwd system power meter on the
Controller HOME screen as shown below.
7. Continue to slowly raise the FWD power until you reach the full 280W, or your
desired TPO. Be careful to make small increases in the value of POWER as you
approach the desired output level.
8. Check the SNR and Shoulder (LIMD and UIMD) RF performance of your
system on the Exciter hi level status screen as shown below. Linear and Non-
Linear corrections were already performed and optimized at a TPO of 280W in
the factory and so the stored correction coefficients should produce good results.
If you are operating at a TPO less than 280W and wish to rerun corrections,
please proceed with the following steps, otherwise please skip ahead to step 12.

9. (Optional Step - Rerunning Corrections) If you are operating at reduced power
and wish to rerun corrections to achieve better performance, you may now
perform Linear and Non-Linear corrections. (Please refer to the Exciter User
Manual for detailed instructions on running corrections). Before running
corrections, it is important to verify proper feedback signal levels. There are two
feedback signal samples used to compute corrections. “RF IN A” (After BPF)
is used to calculate Linear correction coefficients while “RF IN B” (Before BPF)
is used to compute the Non-Linear correction coefficients.
10. (Optional Step) Navigate to the Exciter “DPD” submenu in the Advanced User
menu (simultaneously press Left and Right buttons, then simultaneously press
UP and Down buttons). Be sure the value of Feedback Sample Signal Input
(FSSI) for bothA(after) and B (before) reads somewhere between 45% and 75%
- which roughly corresponds to a value of -15 to -5 dBm as measured on a power
meter (note: the FSSI indicator toggles between A and B and will “flash” when
the signal level is out of range, too high or too low). Add or remove the
appropriate attenuator padding to achieve feedback signal levels in the desired
range. Note the AFTER filter feedback sample is used to compute the SNR and
Shoulder Metrics displayed.
11. (Optional Step) Navigate to the Exciter “SYSTEM” submenu and select
UPDATE underADPC to run corrections. The exciter will then proceed through
4 stages of correction, computing Linear and Non-Linear corrections, and
automatically saving the coefficients into non-volatile memory upon
completion. The correction process typically takes from 8-10 minutes to
complete while real-time performance metrics of SNR and Shoulder
performance are displayed on the LCD.
12. Check RF Performance metrics (SNR, LIMD, UIMD) on the front panel screen
of the exciter.
Your TX should now be up and running properly into your load or on-air
antenna. Continue to monitor system parameters as you allow the transmitter to
operate and stabilize at full output power for another 30 minutes.
13. Navigate to the CAL setting under theAD3Advanced submenu and select CAL
then press OK to calibrate the FWD PWR meter on the Exciter front panel to
100%.
14. To turn the TX On/Off, please use the RF On/OFF control in the RF submenu
of the exciter LCD or the exciter web interface.

15. For Remote TX Monitoring and Control, you may network to the Exciter
REMOTE RJ-45 rear panel connection at 192.168.1.143 – you can change the
exciter ipaddress by navigating to the CONFIG submenu (simultaneously press
Left and Right buttons) and change the value of IP (please reference your
Exciter User Manual for details).
16. If using the Exciter Built-in remote web interface for remote control, please be
sure to set the Exciter to REMOTE mode (set CTL to RMT) before leaving the
transmitter site. The Remote/Local setting is located under the SYSTEM
submenu. Most of the Local TX controls are available on the remote web
interface, including On/Off, Raise/Lower power, etc. (refer to the Exciter user
manual for details).
