The PDI-60SFAS 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. 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-60SFAS would be considered a best buy. $700.00
