DESCRIPTION:

The PDI-60M is a PLL synthesized, SAW filtered, frequency agile modulator. It offers 133 TV channels at an output of 60dBmV. This exceptional unit is manufactured and tested to the highest standards and complies with all FCC requirements. The PDI-60M covers all cable channels from 2 through 134 (54-860MHz) including A-5 to A-1 and HRC. Channel selection is accomplished with "user friendly" up/down controls on the front panel. The selected channel is then automatically locked into memory to insure correct operation after a power failure. For flexibility in operation the PDI-60M has three IF loops. These can be used where control of video, sound, or composite signals are necessary such as scrambling, and /or emergency alert insertion. A 4.5MHz audio carrier input is supplied for microwave or external stereo. An optional internal stereo encoder is available.
