| The ZDM Series are agile audio/video demodulators. Two versions are available, the ZDM-750B for CATV applications and the ZDM-806 for VHF & UHF applications. The ZDM-750B demodulates standard CATV, IRC and HRC channels. It employs a double conversion tuner for optimum "Cherry Picking" of CATV channels in preparation for remodulation. The input frequency range is agile, allowing selection of any CATV channel from 54 to 750 MHz. Baseband audio and video are provided as outputs. The ZDM-806 can demodulate any single VHF & UHF channel in the 54 to 806 MHz frequency range. It is ideal for off-air signal processing (audio/video processing and remodulation) applications. Baseband audio and video are provided as outputs. Both units offer agile channel selection, via front panel LED displays and channel up/down buttons, permits on-the-fly channel changes. A channel lockout mode is also provided to prevent accidental channel changes.
