THE PRODUCT, which was 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. The measurable item includes: power measurement, MER measurement, BER measurement, Constellation, channel measurement, tilt measurement, scan measurement, spectrum measurement, carrier noise ratio measurement and rail voltage measurement. Make the corresponding choice according to different occasion.

The inside process chip adopts extensive integrated microprocessor, which is special to most advanced tester in the world at present. It has many characteristics such as complete function, fast processing speed, low static power consumption, small and high dependability. The peripheral circuit uses its special integrated package design according to corresponding function. The appearance adopts the human mechanics principle, it can be held firmly by single-hand and operated.
