The PDI-60MS is a PLL synthesized, SAW filtered, frequency agile stereo modulator. It offers 138 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-60MS has three IF loops.FEATURES:• UL Listed• +60dBmV RF output level• Microprocessor controlled Up/Down channel button• >-60dB spurious performance• FCC offset internally programmed• Professional grade SAW filter• Three loop-through connections• 4.5MHz audio carrier input• 5 year warranty• ISO 9002 certifiedRFOutput Channels UP/DOWN Selectable 2 Through 134; A-5 to A-1Output Level +60dB RangeOutput Level Adjustment 20dB RangeSpurious Output At least 60dB Below Video Carrier (@ +60dBmV Output With Aural Carrier 15dB Down)Broadband Noise 80dB Below Video Carrier (@ +60dBmV Output)Frequency Stability ±5kHz Maximum (±3kHz typical)Vestigial Sideband Resp. -20dB at IF Channel Edge; -60dB at Adjacent Video and Aural Carrier Frequencies and Frequencies Further RemovedVIDEOInput Type Composite Video, Negative Sync.Input Level 0.5 Vp-p Min. for 87.5% Depth of ModulationFrequency Response +0.75dB (10Hz to 4.2MHz)Differential Gain 3% Typical at 87.5% ModulationDifferential Phase <3 Degrees Typical at 87.5% ModulationHum and Noise -60dB Min. at 87.5% ModulationTilt 1.1% Maximum on 60Hz, 50% Square WaveGroup Delay Response Meets FCC Distortion Requirements for Color TransmissionAUDIOInput Type Unbalanced (Balanced optional)Input Impedance 600 ohm high ZInput Level 250mV Min. for 25kHz DeviationFrequency Response Mono ±0.75dB (30Hz to 15kHz)Intercarrier Frequency 4.5MHz ±100HzSTEREO SPECIFICATIONS PDI-60MS ONLYFrequency Response 20Hz to 14kHz + 1dBSeparation 27dB 20Hz to 14kHz TypicalPilot Rejection 50dBSignal to Noise Ratio 60dBAudio Input Impedance 10K ohms unbalanced / 600 ohm optionalNominal Input Level (APL) 0dBm, Adjustable + 10dBDistortion 0.5% Maximum THDSAP SPECIFICATIONS PDI-60SAP ONLY• Input Impedance: 22 ohms• FM Oscillator: At 78.670 KHz is phased locked for stable output.• Carrier Output: bandpass filter with traps at 63KHz and 94KHz • SAP CARRIER KILL: SAP signal can be shut off with the SAP switch atthe front of the unit.
