Product Description

This unit is in nice cosmetic condition and has apparently has not been tampered with. It still has original seals on the demodulators so chances are that it is fine, but we have not tested it and are selling it as is.

The DM-212A and DM-235 Demodulators, provide AM, FM and Pulse detection of input signals centered at 160 MHz. Each demodulator provides a choice of two IF bandwidths, selectable by a front panel toggle switch. The DM-212A provides 10 or 20 MHz IF bandwidths, with a 10 MHz video response. IF bandwidths of 30 or 50 MHz are provided by the. DM-235, with a 25-MHz video response. Both units provide audio and video outputs along with a 160-MHz predetected IF output. In addition, each unit provides AGC and AFC outputs for control of the associated tuner (typically a WJ 9080B Tuner).
