FREQUENCY AGILE MODULATORS
HMA SERIES
The HMA-550H and the HMA-860H are commercial grade, SAW filtered, frequency agile modulators specifically designed to meet the highest CATV performance standards. All channels are easily selected using front panel buttons and verified with an easy-to-read LED channel display. The modulators feature extremely low out-of-band noise allowing their use in large channel capacity head-ends. The HMA-550H and the HMA-860H modulators are the ideal choice for any system where performance, flexibility, and reliability are required. |

DEMODULATORS

The HDD Demodulator permits the delivery of digital television signals in analog format directly to a television. They also interface easily with existing analog modulators on CATV networks. This high performance digital receiver allows for the reception and demodulation of an 8VSB (Off-air SD/HD digital TV Signal) or QAM (Digital CATV) signal into a baseband NTSC video and audio output. Closed Captioning Support Non-Volatile Memory Agile Input LED Channel Display
HPH SERIES AGILE PROCESSORS

The HPH-860 frequency agile processors have been designed to convert any off-air cable channel input to any cable channel. All channel conversions are performed using simple front panel buttons and a large LED display indicating input and output channels. Frequency control is accomplished by a microprocessor controlled, PLL synthesized tuning circuit to assure accurate, stable operation. The HPH-860AD hetrodyne processor can be used to process digital off-air or cable channels while retaining the digital format. 60 dBmV Output Precise Signal Regulation Front Panel LED Channel Display Switching Power Supply (Operates from 90-260 VAC)
RACK MOUNTED AMPS

HSA-* SINGLE CHANNEL AMPLIFIER The HSA is a highly filtered, AGC’d, single channel amplifier capable of providing the highest off-air signal performance in an adjacent channel head-end. The high out-of-band rejection coupled with a low input AGC threshold make the HSA the ideal choice for on-channel processing. A low noise input amplifier provides the cleanest pictures at low-input levels. Built-in Adjacent Channel Filters Low Noise Input Circuitry Low AGC Threshold (-2dBmV) High Out-of-Band Rejection AC Convenience Outlet

HCA-3051RK and HCA-3086RK are high-output hybrid rack-mountable amplifiers perfect for any head-end system. These high performance amplifiers use push-pull CATV hybrid circuitry providing extremely low noise and distortion. Front panel adjustable slope and gain controls allow easy system balancing.

Single Satellite Switch
The HMS-16APR is a rack mounted multiswitch specifically designed for SMATV applications. The switch generates the voltage required for powering a dual LNB (13 & 18 volts). Also provides amplification to help overcome the insertion loss of the 16 outputs.
Multi-satellite Switch
The HMS-412ARK is a 4 LNB input, 12 output multiswitch designed to provide solid state multi-sat switching for head-end systems. This unit provides 13 and 18 volts as well as 22 kHz tone to lock the LNB’s on the required satellites.

AHC-16-860 ACTIVE COMBINER The AHC-16-860 is a high isolation, 16 channel active head combiner. With its internal CATV hybrid push-pull amplifier, the AHC-16-860 is able to compensate for its insertion loss and drive the cable system as well. The AHC-16-860 features a front panel gain control and a -20 dB test port. CATV Hybrid Amplification High Output High Isolation Low Distortion AC Convenience Outlet
CONVERTERS

The SHC converter is ideal for use in head-end and local origination applications. In head-end applications, the SHC is used to convert the incoming sub-band (T7 – T13) to VHF (7 – 13).
For local origination applications, the SHC can be used in offices, hospitals, or any situation where sub-band can be utilized to allow a TV within the system to view channels not available to others. These converted sub-band channels can then be redistributed using standard processors and demodulators.
