FIELD: radio engineering.
SUBSTANCE: device consists of modulated signal source (1), amplifier (2), pulse shaper (3), source of threshold voltage (4), lower level comparator (5), upper level comparator (6), element OR (7), pulse generator (8), element AND (9), the first counter (10), the second counter (11), unit of galvanic isolation (12), communication channel (13), converter of current into voltage (14), threshold element (15), receiver of modulated message (16).
EFFECT: development of device for monitoring of communication channels condition in data transmission, which provides control of communication channel resistance change, and also more precise control of resistance in case of pulse interference in communication channel.
