Vector Network Analyzer TW4650



Product Overview :


Vector Network Analyzer TW4650 include TW4650A( 10MHz ~ 13.5GHz )? TW4650B (10MHz~26.5GHz)?TW4650C(10MHz~40GHz)and TW4650D(10MHz~50GHz. They are new generation of products produced by Techwin based on many years of scientific research and production experience in vector network analyzer. In terms of hardware, brand-new design concept and technical proposal have upgraded key performance indexes (KPI) of complete machine such as measuring speed, dynamic range and measurement stability; in terms of software, embedded computer system (ECS) with high-performance microprocessor chip and Windows-based operating system have greatly improved interconnectivity and easy use of complete machine. Vector Network Analyzer TW4650 provide multiple calibration types including frequency response, single port, response isolation, enhanced response and full two-port calibrations; offer many display formats such as logarithmic amplitude, linear amplitude, standing-wave ratio (SWR), phase, group delay, Smith chart and poplar coordinates, etc.; are designed with several kinds of standard interfaces: including USB, LAN, GPIB and VGA, available in multifunction parameter testing of mixer/converter, active intermodulation distortion and harmonic distortion, gain compression two-dimensional sweep and pulse network S-parameters, which allows it to accurately measure the amplitude-frequency characteristics, phase-frequency characteristics and group delay characteristics of microwave network. They are widely used in the field of transmitting/receiving (T/R) module measurement, measurement of dielectric material properties, measurement of microwave pulse characteristics, photoelectric properties measurement, which is absolutely necessary for the scientific research and production process of phased array radar, communications, microwave and RF components and parts.
