ST-2150Q/ST-1185Q is newly designed for both installation and maintenance of HFC system. It can Measure and display main parameters in the HFC network (channel power, MER, BER, Constellation Diagram), signal level on any frequency, the amplitude of the carriers singly in the whole system range, and
any frequency, the amplitude of the carriers singly in the whole system range, and etc. It inherited all ST1151B’s strong points. The Analogue channel, QAM and FM channel can be set and tested efficiently; it also supports C/N measurement, voltmeter function, spectrum analysis and data logging. It is easy for ST2150Q/ST1185Q to obtain a report of test data via PC or printer. Additionally, ST2150Q/ST1185Q has a wider frequency range: 5MHz ~ 870MHz, so that models support return path testing
