Revision 2.2
Description 1-1
1. DESCRIPTION
Nucomm’s ChannelMaster TX1 is a
Digital-Analog Portable Microwave
Transmitter. The tripod mounted
Microwave 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.
Standard features include fifteen presets
(the first five presets allow single button
operation), integrated dynamic color
bars, HD transport capability, field
programmable RF and Audio Sub-
carrier frequencies, RF power control,
local LCD display for control and
monitoring. Also, special menus have
been included to ease the BAS (US)
relocation process.
The ChannelMaster is fully integrated
with an Analog FM modulator, compliant
super-low delay MPEG 2 Encoder, and
Multimode Digital Modulator. Available
modulations include FM (NTSC / PAL),
COFDM, optional single carrier QAM,
and optional VSB. As additional digital
modulation formats become available,
the system can easily be software
updated. The ChannelMaster TX1 is
designed to be an extremely flexible
system, with limited circuit complexity.
The system video inputs include SDI,
ASI, Composite Video and External
70 MHz. The system comes standard
with two analog audios or one digital
AES. Optionally, the system can
support four analog audios or two digital
AES.
Other available options include: high
power amplifier, multi-band operation,
and standby power sourcing, as well as
other features and options. Contact
Nucomm for details.
This manual is written in general form to
cover all configurations and options for
the series within the 1.00 GHz to
15.5 GHz frequency range.

Revision 2.2
1-2 ChannelMaster TX1 Transmitter
Given the model number, the unit' configuration can be determined using the following:
AAAAA – CMTX1 – BBCC – X – YZ
Options
Emphasis Type
Specified Frequency Plan
Power Output
Model
Generalized Frequency Band Designator
Where:
AAAAA = mean frequency band center in GHz rounded to the closest GHz. This
number is then multiplied by 10. For multiple bands, each center frequency designation
is separated by a backslash "/".
BB = Used to identify the power output, per the following Power Output Designators:
Power Output is represented by Letters (A-Z; A=1, B=2, C=3, etc) for the analog power,
and Numbers (0-9) for the digital power. For example, a 5W Analog / 2W digital system
would be described with a power indicator of "E2". A Dual-Band system would have
two sets of power indicators, to show the power levels at both bands.
CC = Nucomm assigns a frequency chart number for each unique frequency channel
combination. Contact your Nucomm representative for further information.
X = Type Emphasis; 1 = NTSC and PAL M; 2 = PAL B/G
YZ = Miscellaneous options as listed below (append as many letters as needed)
M = FM only
M1 = COFDM only
M2 = FM / COFDM
M3 = FM / COFDM / DVBS
M4 = COFDM / DVBS
M5 = DVBS only
M6 = External 70MHz
Options that are not a standard part of the system, will be shown by shaded text as
shown here.

Features 2-1
2. FEATURES
2.1 Configuration
Nucomm’s ChannelMaster TX1 Series
Digital-Analog Portable Microwave
Transmitters are among the most
comprehensive portable radios in the
world. The ChannelMaster TX1
features are designed for both Analog
and Digital operation in portable links,
as well as helicopter and ENG/OB
applications. In the Digital mode, the
ChannelMaster accepts an external
digitally modulated signal with QPSK,
8PSK, 16QAM, 8VSB, COFDM, DVBS
and multi-level FSK. We also offer
internal FM, COFDM, VSB, and DVBS
(future).
The rugged ChannelMaster TX1
includes video and audio processing
boards, power supply, 70 MHz
modulator, power amplifier, up-
converter, and low noise frequency
synthesizer enclosed in a weatherproof
enclosure that typically mounts on a
tripod. See Figure 1−1 for the system
block diagram.
The antenna (supplied separately) can
be either mounted directly to the
transmitter using one of our available
mounting adapters, or can be remotely
mounted to the transmitter and
connected via standard RF cables with
N-Type connectors. Many state-of-the-
art options are available on the
ChannelMaster, some not found on any
other portable Transmitters, leading to a
more cost-effective approach to portable
Microwave Systems.
The Nucomm ChannelMaster TX1
Series of transmitters are available in
single, dual, and multi-band models.
The ChannelMaster TX1 series radios
provide full coverage of the 2, 7, & 13
GHz US frequency bands and/or other
bands as required internationally, from
1 GHz to 15.5 GHz. The US frequency
bands are given in Table 1 through
Table 5. Band and channel selections
are made and clearly displayed via the
Front Panel LCD Interface.
Prime Power
All ChannelMaster TX1 transmitters
feature a built-in power supply, which
operates on power ranging from 90 to
240 VAC (40 to 60Hz), or +11 to
+32 VDC without the need for internal
jumpers or switch settings.
Audio Sub-carriers
Two (four optional) field programmable
synthesized audio sub-carriers feature
individual LINE/OFF/TONE source
selection, and automatic gain control
(AGC). The sub-carrier frequencies,
Mode, and additional gain are front
panel adjustable using the LCD
interface.
Standby Mode
In the Standby mode, the
ChannelMaster TX1 is powered on, but
the RF output is muted, enabling the
transmitter to be tuned safely without
radiating off-frequency emissions. The
ChannelMaster TX1 will remain in
Standby until on-frequency lock has
been obtained. Switching from Standby
to the Normal (operating) mode results
in instantaneous on-frequency

Revision 2.2
2-2 ChannelMaster TX1 Transmitter
transmission. If the synthesizer has not
attained a lock when the unit is switched
from Standby mode to Normal, the unit
will remain in Standby until on-frequency
lock has been obtained.
Signal Strength Indicators
Transmitted signal strength is indicated
on the LCD display by a digital readout.
The digital readout indicates the
transmitted signal level directly in watts.
(This function is intended as an
approximate reading of power only.)
Video Presence Detector
The Video Presence Remote Standby
mode enables the camera operator to
remotely turn on the color bars or put
the ChannelMaster TX1 in standby.
Internal Self-Test
Built-in diagnostic features include a
1 kHz audio test tone and a 761.5 kHz
(1.512 MHz for PAL) video deviation test
signal.
Other Standard Features:
•Digitally synthesized microwave
oscillator tuning
•Independent Gain Control for audio
