The AD-1 Series are professional quality, agile audio/video demodulators. These units provide audio and video output from any channel in the 54 to 88 and 108 to 806 MHz frequency range. The AD-1 Series is ideal for signal monitoring and signal conditioning (audio/video processing and remodulation) applications. Agile channel selection permits on-the-fly channel changes.

The AD-1 Series takes a single channel in the 54 to 88 and 108 to 806 MHz frequency range and demodulates the audio and video information. Baseband audio and video, as well as 4.5 MHz audio subcarrier and multiplex audio, are provided as outputs. The AD-1 features phase locked loop synthesized frequency control with a tuning increment of 250 kHz. Channel selection is accomplished with the use of simple to use front panel accessible dip switches. A Nyquist filter provides stable, accurate demodulation of the vestigial sideband signal. Additionally, this filter minimizes distortion and preserves the timing of the signal. Delayed AGC circuitry automatically compensates for input signal variations. The AD-1 Series also utilizes a quasi-synchronous video detector that has low differential gain and minimal phase distortion. A quadrature audio detector delivers a very low distortion audio output. Broadband multiplex audio and 4.5 MHz audio subcarrier outputs permit use in BTSC stereo applications.

Features

  • Rack Mountable - 1 EIA (1.75") Rack Space
  • UL Listed with Three Year Product Warranty
  • 250 kHz Tuning Increment - Supports Broadcast, CATV and UHF Assignments Including HRC & IRC
  • AGC Circuitry Automatically Compensates for Input Level Variations
  • 4.5 MHz Audio Subcarrier and Broadband Multiplex Audio Output Permits Use with BTSC Stereo Applications
