| HCP2550A
HETERODYNE CHANNEL PROCESSOR |
The Drake HCP2550A
is a high quality, frequency agile channel processor capable of converting
any VHF, UHF, or CATV input signal to any standard output channel
between 54 through 550 MHz. Input and output frequency, including
output frequency offset, are easily set with front panel pushwheel
switches. A/V ratio and output controls are also provided along with
IF loop-through connections to offer exceptional flexibility.
- Synthesized input tuning of
Off-Air TV channels 2 through 69, standard CATV channels 2 through
125, and IRC, HRC channels 1 through 125. All set by a front panel
pushwheel switch.
- Synthesized RF output on CATV
channels 2 through 78 and 95 through 99, set by a front panel
pushwheel switch.
- Selectable pre-amp and AFC
provides stable reception of weak or out-of-tolerance signals
- Switch selection of plus, minus
or no offset of output frequency
- Dual SAW filter IF allows adjacent
channel operation in a crowded CATV environment
- Selectable and adjustable threshold
level allows internal carrier substitution for below threshold
input signal levels
- IF loop-thru connections for
scrambling encoders or IF stereo processors
- High output power adjustable
to +60 dBmV
- Available with "T" Channel
upconverter option for reception of channels T7 - T14.
- Emergency Alert System (EAS)
ready with alternate composite IF inputs.
