DESCRIPTION
1.1 Introduction
Nucomm’s ChannelMaster TX7 is a
Digital-Analog Portable Microwave
Transmitter. The tripod mounted Micro-
wave Transmitter System is designed to
operate in any specified band in the
1.00 GHz to 15.5 GHz frequency range.
Each unit is field programmable and
configurable to meet a wide range of
customer requirements. The TX7 may
be configured for dual band or tri-band
operation.
The ChannelMaster TX7 is designed to
be an extremely flexible system. It is
fully integrated with an MPEG2 compli-
ant super-low delay Encoder, a Multi-
mode Digital Modulator, and an Analog
FM modulator. Outputs include ASI and
microwave RF in the frequency bands
mentioned above.
The CMTX7 design uses advanced
software defined radio techniques and
supports both COFDM and VSB digital
modulation. As additional digital modula-
tion formats become available, the sys-
tem software can easily be updated to
support them.
The ChannelMaster TX7 includes inputs
for Composite Video, HD-SDI and SD-
SDI, ASI, Firewire, and 70 MHz modu-
lated signals.
The system comes standard with two
analog audio channels or one digital
AES channel. Optionally, the system
can support four analog audio channels
or two digital AES channels.
The system features an LCD display for
control and monitoring, an easy to use
menu driven user interface, fifteen user
defined presets, field programmable RF
and Audio Sub-carrier frequencies, ad-
justable RF power, and integrated dy-
namic color bars. A built-in serial inter-
face can be used for remote control and
monitoring. Special menus have been
included to ease the BAS (US) reloca-
tion process.
Available options include a high power
amplifier, multi-band operation, and
standby power sourcing. Contact Nu-
comm for information about additional
options.
This manual covers all configurations
and options for the series within the 1.00
GHz to 15.5 GHz frequency range.
