Features 2-5
2.9 Multi-band Microwave
Output
Nucomm’s ChannelMaster transmitters
are available in single, dual, and multi-
band models.
An antenna (supplied separately) can be
either mounted directly to the transmitter
using available mounting adapters or it
can be remotely mounted and con-
nected to the transmitter via standard
RF cables with N-Type connectors.
The Channel-
Master 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 3-2 through Table 3-5. Band and
channel selections are made and clearly
displayed via the Front Panel LCD Inter-
face.
2.10 Signal Strength Indicators
Transmitted signal strength is indicated
on the LCD display by a digital readout
that indicates the transmitted signal
level directly in dBm. (The signal
strength display is intended as an ap-
proximate reading of power only.)
2.11 Video Presence Detector
The Video Presence Remote Standby
mode enables the camera to remotely
turn on the color bars or put the Chan-
nelMaster in standby based upon the
detection of video presence at the input
port.
2.12 Remote Control Feature
Two RS232/RS485 ports are available
to control the system remotely. One is
located on the left side of the unit’s
housing, and the other is located within
the front panel power supply connector.
2.13 Power Supply
All standard ChannelMaster's feature a
built-in power supply, which automatically
covers all the input voltage ranges listed
in Table 3-1, without requiring any user
intervention.
Optional Power configurations:
Standby Power: For power
redundancy, ChannelMaster's can be
configured to accept both AC AND DC
simultateneously. The unit will continue
to operate if at least one of the inputs is
present.
DC Only: The ChannelMaster may be
configured for "DC only" source voltage.
2.14 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.
2.15 Other Standard Features
Digitally synthesized microwave os-
cillator tuning
Independent Gain Control for audio
inputs (Two audio sub-carriers stan-
dard, four optional)
Selectable power levels
Test Pattern/ID Test Generator with:
o SMPTE RS-170A Color Bars
(EBU Pattern)
