The PDI-60SFA 60dBmV output video and audio modulator offer the user a high degree of performance and flexibility for very nominal cost. The PDI-60SFA is tunable for any CATV channel from 2 to 134 which includes A-5 to A-1 and UHF/VHF channels 2 to 69. It is PLL controlled with SAW filtering. This offers stable performance and allows maintenance free adjacent channel configuration. It has a composite IF Loop which allows encoder and video override applications. Its video dynamic range insures 87.5% modulation depth over a wide video input range. The power supply used is a high efficiency switching mode unit. It works over a wide voltage and frequency input range eliminating the need for additional voltage regulating equipment. For a low cost agile modulator, the PDI-60SFA would be considered a best buy.FEATURES:• +60dBmV RF output level • Phase lock loop frequency control prevents frequency drift • Simple push button selection for 134 channels • User friendly controls • SAW filtering for maintenance free adjacent channel configuration • Excellent video and audio linearity for superior picture quality • BTSC stereo generator plug in, PDI-60SFAS model ONLY! • IF loop through for emergency alert or scrambling encoding • Switching mode power supply allows operation worldwide • Plug in power cord allows for any AC plug configuration • Auxiliary AC outlet • Test point for ease of monitoring • UL listed Canada/U.S. • Also available in all PAL configurationsRF SECTION Frequency Range 2-134 (54 to 860MHz [STD])Frequency Stability +/- 10KHz (+/- 5KHz for offset channel)RF Output Level +60dBmV min.RF Level Control Range 0 to -20dBAural Carrier Control Range -13 to -20dB VIDEO SECTIONVideo Input level 0.7 to 1.5 Vp-pVideo Impedance 75 ohmVideo Response +/- 2dBS/N > 60dBC/L Delay +/- 60ns (meets FCC regulation)Differential Gain < 4%Differential Phase < 3 deg AUDIOAudio Input Level 500mV RMS for +/- 25KHz deviationAudio Impedance 600 ohm unbalanced (10K ohm for stereo mode)Audio Response +/- 1.5dB 50Hz to 16KHzPre-emphasis 75µs defeatableTHD 1% max. @25KHz dev.
