DTMR A850: ATSC Digital TV Monitoring Receiver

General view of the basic remote controller data concentrators

The DTMR-A850 has been designed to monitor ATSC digital terrestrial transmitters

MER measuresMeasuring the ATSC signal at the transmitter output and/or at the antenna is a must to have a real performance measurement of an 8VSB transmission system. To get a real and accurate (±0.5dB) measure, DTMR-850 reaches quality measurement performances (>38dB MER) achievable only with costly studio measurement instruments. Automatic alarms on user preset thresholds, both on level, MER, S/N and eye aperture, let engineers keep confident that the digital signal will cover all the planned reception area.
Also if DTMR-A850 can be used on the field to check signal coverage and quality, it has been designed to test the transmitter at site, without any quality compromise.
