Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD Introduction
ATSC Transmitter/Regenerative Translator
Instruction Manual, Rev. 2 1
Introduction
Manual Overview
This manual contains the description of the Innovator CU0TD-1/CU0RD-1 –
CU4TD/CU4RD Transmitter/Regenerative Translator and the circuit descriptions of the
boards, which make up the system. The manual also describes the installation, setup
and alignment procedures for the system. Appendix A of this manual contains the
system level drawings for the Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC
Transmitter/Regenerative Translator System that was purchased. NOTES: If your
system contains dual exciters with a remote interface panel and Exciter control panel,
information and drawings on the system and panels are contained in the separate
remote interface panel instruction manual. Information on the optional K-Tech Receiver
or Signal Converter, if part of your system, is contained in the separate manufacturers
supplied manuals.
UBS-Axcera Numbering System Explanation
The UBS-Axcera numbering system is explained as follows. The following example is for
a CU0TC-3 Transmitter system.
C – CX Series
U – UHF Frequency Band
0 or X - Number of external Power Amplifier drawers
T - Transmitter, L - Echo cancelling repeater, R - Regenerative translator
C - COFDM (DVB-T/H/T2), I - ISDB-T, D - ATSC, No letter or blank means analog.
-3 = 50W or (861 devices), -2 = 30W or (861 devices with smaller power supply), -1 =
3W or 5W depending on the modulation. -4 = 888A. For ATSC there is also a -5 at
150W output but it is the same as the -4.
The following example is for a power amplifier drawer CUBP888A-4.
1 | 2 | 3 | 4 | 5 | - | 6 | - | 7 |
C U B P 888A - 4
Position Chars Description
1 1 Transmitter Line (C=CX, 6=6X, H=HX)
2 1 or 2 Frequency Band (U=UHF, HV=HB VHF, LV=LB VHF, etc.)
3 1 Version (ex. A-line, B-line, etc. - typically matches
transmitter model version)
4 1 Use (E=Exciter/Driver, P=PA)
5 up to 4 Transistor number (might need to abbreviate)
6 1 or 2 Number of transistors in final output stage
7 up to 4 Additional field to include other important info
(ex. distinguish bet single or N+1 supplies, or other things
not covered in the number
CUBP888A-4: Line C, Frequency UHF, Version B, Use PA, Transistor Number
888A, number of transistors in final output stage 4.
