Blonder Tongue AQT
The Blonder Tongue AQT Transcoder is a modular unit that receives either an 8VSB (Off-air Digital) or QAM (CATV Digital) signal, and
transcodes it to any CATV QAM channel. The transcoding enables televisions with QAM digital tuners to seamlessly view the 8VSB Off-air
digital signals on cable television frequency assignments without having to change the television tuner input from CATV mode to Off-Air
mode. The input digital signal is stripped of its original digital modulation (8VSB or QAM), leaving just the basic data stream. The Blonder Tongue AQT then
creates a new, clean QAM carrier and reinserts the original data stream on to this new QAM carrier. If the original channel was encrypted, it
will remain encrypted, if the original channel was in the clear, it will remain in the clear. The only modification to the original data stream that
is performed is changing the data rate when converting an 8VSB signal to a QAM signal. This rate change is done via Null Packet processing
and does not affect the encryption in any way. The regeneration of a new, clean QAM signal is also useful for digital cherry-picking from an
existing digital channel line-up, or regenerating a channel for optimal Modulation Error Ratio (MER) performance.
Blonder Tongue BTY Series
The Blonder Tongue BTY Series of professional quality antennas include single channel and broadband models designed for a variety of UHF and VHF applications. The BTY Series features high gain, narrow beamwidth, and low side lobes.
Blonder Tongue CMA Series
The Blonder Tongue CMA Broadband Preamplifier Series includes professional quality, low noise. broadband VHF & UHF preamplifiers. CMA's are available in four different models for amplification of low band VHF, high band VHF, broadband VHF, or broadband UHF. The CMA Series are housed in a die-cast case.
Blonder Tongue CMA-b & SCMA-Ub Series
The Blonder Tongue CMA-b and SCMA-Ub Single Channel Preamplifier Series are professional quality, very low noise, single channel VHF/F< and UHF preamplifiers. The CMA-b is optimized for a single VHF channel or FM Band (88-108 MHz), while the SCMA-Ub is optimized for a single UHF channel. These preamplifiers can accept a wide range of input signal levels and offer excellent gain, making these units ideal for difficult signal areas.
Blonder Tongue DAP
The Blonder Tongue Digital to Analog Processor (DAP) is a complete single channel solution for delivering digital television programming over existing analog networks. The Blonder Tongue DAP is a perfect transition unit for existing analog processors to ensure uninterrupted delivery of off-air signals from new digital broadcast sources. The Blonder Tongue DAP permits operators the ability to embrace the approaching FCC mandated February 17, 2009 digital transition deadline and ensure uninterrupted delivery of off-air programming to subscribers. By deploying the DAP now an operator can immediately take advantage of the superior quality digital off-air broadcast transmissions that are currently available. The unit supports the decoding of all 18 ATSC (Advanced Televisions Systems Committee) standard formats including 8VSB as well as Annex B QAM 64 & QAM 256 signals.
Blonder Tongue DHDP Series
The Blonder Tongue DHDP Series (Digital High Definition Television Processor) is a two-unit system consisting of a Downconverter unit which acts as the input section and an Upconverter unit which acts as the output section. Both units are housed in a single MICM style die-cast chassis and are available in both horizontal and vertical versions.
Blonder Tongue PS Series
The Blonder Tongue PS-1526 and PS-1536 are professional quality, DC power supplies designed to power SCMA and CMA Series antenna preamplifiers. Both units provide -21 VDC and allow for a combined VHF and UHF feed to be diplexed with the power feed. The PS-1536 has a dual output for powering two loads, with a maximum current rating of 100 mA. The PS-1526 has a single output for powering one load, with a maximum current rating of 40 MA.
Drake DAD860
The Drake DAD860 Digital to Analog Decoder is a digital demodulator and decoder, for ATSC 8VSB broadcast or in-the-clear QAM television signals, that delivers a standard NTSC composite analog video and stereo audio output.
This device, used in conjunction with an analog NTSC modulator, allows a cable system operator to continue to
provide analog versions of services that will only be available to him as digital in the future. It may also be utilized to
provide the alternate digital channels now available from many broadcasters. The DAD860 is packaged in an extruded aluminum module that is compatible with the Drake RMM12 or RMM4 rack
mounting units normally used for our analog mini-rack components. The DAD860 is one unit wide and thus takes one
of 12 available slots in the RMM12. There is a companion controller, the DAD860 Controller, that can be used to
program and monitor between one and ten DAD860 modules. The controller module is two units wide as mounted in
the RMM12.
Harris/Videotek DDM-800
The Harrisฎ Videotekฎ DDM-800 is a Multi-Channel 8VSB Frequency Agile Demodulator. The Harris DDM-800 is a compact, one rack-unit Frequency Agile Digital Demodulator capable of demodulating 8VSB,
64 QAM and 256 QAM modulated signals, and converting them to DVBASI output format. The DDM-800 can
house up to four separate demodulators in one package. The demodulated MPEG-2 output streams can then
be locally decoded, analyzed, multiplexed or passed to a cable facility via QAM modulators or to a data
distribution network. The Harris DDM-800 front panel interface enables quick setup through direct entry keypad and navigation keys. The
front panel indicates the current channel number or the center-frequency.
The status display for each demodulator shows SNR, Bit Error Rate (BER), and fine tuning offset. External
communications supports configuration through an intuitive Web Browser GUI via the 10/100 Base-T Ethernet
connection. The resident SNMP agent enables straightforward integration into Headend, Station, or Uplink
network control and monitoring systems with real-time clock for time stamp on alarms.
