QT - Modular QPSK/QAM Transcoder
The QT Series is a Modular QPSK to QAM Transcoder supporting
up to eight QAM Transcoder Modules, interfaced with a Power &
Control Module housed in a specially designed 3RU chassis.
The unit transcodes any 24-36 MHz wide QPSK modulated
satellite signal to a 6 MHz wide QAM modulated IF signal and
translates it to any CATV RF channel assignment in the 54-864
MHz frequency band.
The QT Series features a back-lit LCD display with front panel
accessible push button controls providing access to all vital unit
information, facilitating easy set-up and troubleshooting.
Interfacing the QT with Blonder Tongue’s QCentral computer
software provides off-site, remote operation and control including
digital adjustment of the QAM RF output level.
