Description:
The introduction of the DRAKE DQT1000 represents the addition of yet another unique product to DRAKE's growing line of products for the reception and processing of digital television signals. The DQT1000 is unsurpassed in combining multiple functionality in one single unit of rack space. It contains two tuner/demods with 8VSB and QAM capabilities, MPEG program filtering, a transport stream multiplexer, a QAM modulator and a low noise high output power agile upconverter. In addition it may be special ordered with a single tuner/demod and a field installable ASI Input Module is available.
The DQT1000 can be remotely controlled and programmed via its RS232 serial interface.
The DQT1000 is capable of transcoding several different digital input combinations into a QAM output on any desired broadxast or cable channel for insertion into a cable system channel map. A program filtering function allows inclusion or deletion of any individual program in the digital transport stream. |
Features:
 Front panel backlit display and buttons allow easy setup and monitoring of operating mode and parameters.
High output, 61 dBmV, agile QAM modulator and upconverter are built in, operating up to 1024QAM.
RS232 serial interface provides for remote control programming and monitoring.
The field installable ASI input or second tuner/demodulator modules (if not factory installed) add the transport stream multiplexing function.
Input tuner/demodulator(s) tune off-air or CATV channels between 54 and 860 MHz and provide demodulation of 8VSB, 16VSB, or QAM modes from 16QAM to 256QAM. ATSC, ITUA (DVB), or ITUB (DigiCipherŪ II) FEC modes are supported.
A wide range equalizer suppresses multipath effects on ATSC signals.
Off-air ATSC mode incorporates a NTSC co-channel rejection filter.
Major channel number pass through or remarking to RF output channel is selectable.
Operates in a fixed output clock mode and processes null packets when required to maintain the set fixed clock rate.
Program filtering allows the user to select which MPEG programs present in the input streams are to be included in the output or discarded.
PSIP options include several modes of operation.
MPEG program numbers and minor channel numbers of input B or the ASI input may be offset to prevent duplication of the input A numbering.
Rewriting of the MPEG tables is provided when two input streams are multiplexed.
PCR restamping is performed when necessary.
61 dBmV QAM low phase noise output is agile on CATV or broadcast channels from 54 to 1002 MHz.
High MER output signal quality. |
