Introduction
Manual Overview
This manual contains the description of the Innovator CHV400BTD ATSC Transmitter 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 and parts lists for the
Innovator CHV400BTD ATSC Transmitter System. Appendix B contains the Tray,
subassemblies and boards drawings and parts lists for the CHV200BTD Driver Tray.
Appendix C contains the Tray, subassemblies and boards drawings and parts lists for
the CHV400B Amplifier Tray. NOTE: Information and drawings on the Axciter, if part of
your system, are contained in the separate Axciter Instruction Manual.
Assembly Designators
Axcera has assigned assembly numbers, Ax designations such as A1, where x=1,2,3…etc,
to all assemblies, modules, and boards in the system. These designations are referenced
in the text of this manual and shown on the block diagram and interconnect drawings
provided in Appendix A.
The cables that connect between the boards within a tray or assembly and that connect
between the trays, racks and cabinets are labeled using markers. Figure 1 is an
example of a marked cable. There may be as few as two or as many as four Markers on
any one cable. These markers are read starting farthest from the connector. If there
are four Markers, the marker farthest from the connector is the system number such as
system 1 or transmitter 2. The next or the farthest Marker is the rack or cabinet “A”
number on an interconnect cable or the board “A” number when the cable is within a
tray. The next number on an interconnect cable is the Tray location or Board “A”
number. The marker closest to the connector is the jack or connector “J” number on an
interconnect cable or the jack or connector “J” number on the board when the cable is
within a tray.
