Model
OTD-3000 54-801MHz PAL
Demodulators, 1 IF, 1RU
|
Model OTD-3000 Frequency Agile TV Demodulator Front and Rear Views |
||||
| The Model
OTD-3000 full featured agile demodulator series is
available in four standards: NTSC, PAL, B/G, PAL I, and PAL D. The
OTD-3000 will demodulate NTSC frequencies from 55.25MHz (Ch. 2)
to 801.25MHz (UHF Ch. 69), and PAL frequencies from 48.25MHz to
855.25MHz, including all cable channels. Sub-band input and/or remote
control capabilities are available as optional features. Locally
controlled channel selection is by front panel DIP switches. The
OTD-3000 features two video outputs, a subcarrier output, rear
panel selectable composite video output, and a 600 Ohm balanced audio
output. A multiplex audio output is also provided for stereo
applications along with an IF output port, which allows the unit to be
utilized as a frequency agile input tuner for processor applications.

Model
OTR-3550 54-801MHz
IN/7-550MHz Out PAL Frequency Agile Processor, 1 IF, 1RU
|
Model OTR-3550 Frequency Agile TV Processor Front and Rear Views |
||||
| The
frequency agile OTR-3550 offers the ultimate in flexibility. It
will select any input channel from channel 2 VHF through channel 69 UHF,
including all cable channels through 470MHz and will select high level
(+60dBmV) outputs on any channel from channel 2 through channel PPP
(547.25MHz). All input and output channels are selectable by front panel
DIP switch. The OTR-3550 offers such features as >80dB
out-of-band C/N ratio, which allows unlimited numbers of
the OTR-3550 to be combined without the need for external
bandpass filters. The OTR-3550 functions automatically with BTSC
stereo or monaural audio carriers.

| Model S450P Heterodyne 54-801MHz In, 450MHz Out NTSC Processor, 1 IF, 1RU | 
Model S450P Heterodyne Processor Front and Rear Views |
||||
| The Model S450P Frequency Agile Heterodyne Processor, offers an economical way to process off-air or cable-delivered signals in CATV headends without sacrificing performance. All adjustments are made via convenient front panel controls; no internal adjustments are required. Input frequency selection is accomplished with front panel DIP switches located behind a sliding cover. The S450P accepts VHF and UHF broadcast channels up to 801MHz and cable channels to 450MHz. Output channel selection is also accomplished with front panel DIP switches that tune in 0.25MHz increments from 50 to 450MHz. Other front panel adjustments include: an audio/video ratio (A/V) control which adjusts the aural carrier from -12dB to -17dB below the video carrier; an offset adjustment control which enables the output frequency to meet FCC requirements; and an RF output level control which can be adjusted 10dB down from typical 60dBmV output. The S450P can accept and process BTSC stereo delivered signals with no added signal degradation. | |||||
