Digital Signal Level Meter
DIGITAL SIGNAL LEVEL METER SM2008
SM2008 series handheld QAM analyzer is designed for both analog and digital TV analysis in HFC network. SM2008 series handheld QAM analyzer incorporates the newest technology, supporting digital signal analysis functions for channel power, MER, BER and constellation diagrams for 16/32/64/128/256 QAM modulation types. Analog channel analysis includes single frequency level, carrier level of full channels spectrum, tilt and carrier to noise ratio. SM2008 also embeds video decoders and allows installers receive and play unencrypted digital and analog TV channel programs directly on 3.5 inch color LCD screen.
