The product, which newly researched and developed, is the integrative high-tech measuring instrument for the transformation of CATV. The main function is to measure QAM digital signal and analogue signal.
Characteristics: the complete function, the fast processing speed, the low static power consumption, small and the high dependability.
Description:
SM2007 series handheld QAM analyzer is designed for both analog and digital TV analysis in HFC network.SM2007 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. SM2007 uses highlight LCD screen and backlight can be set on or off per needed.
