Techwin vector network analyzer for manufacturing wireless device We will try our best to provide products similar to Keysight like X-series vector network analyzer(MXG, EXG,CXG), Rohde & Schwarz vector network analyzer like R&S FSW Signal and Spectrum Analyzer and R&S FSWP Phase Noise Analyzer and VSO Tester, Tektronix vector network analyzer like RSA5000B Real Time Spectrum Analyzer,  Anritsu vector network analyzer like MS2090A Field Master Pro and MS2720T Spectrum Master. You will probably see us at the following exhibitions: EUMV in Europe , IMS in USA, MWC in Spain, EMV in Germany and so on. Product Overview: Techwin TW4650 series vector network analyzer is consist of 10MHz13.5GHz, 10MHzï½?26.5GHz and 10MHzï½?43.5GHz. Techwin TW4650 series reduces cost and enhances price-performance ratio but still maintains the same critical technical specifications with those of high performance instrument, such as sweep speed, dynamic range etc. Techwin TW4650 series offers multiple calibration types including frequency response, single port, response isolation, enhanced response, full dual-port and E-cal. Multiple display types are embedded like logarithm amplitude, linear amplitude, standing-wave, phase, group delay, Smith chart, polar coordinates. Many standard interfaces are available including USB, LAN, GPIB, VGA etc. They can precisely measure characteristics of amplitude-frequency, phase-frequency, and group delay and so on. Main Features: Flexible calibration types, compatible with multiple cal kits Support complicated testing solutions with many windows, multiple channels and fast operation Multiple display types like logarithm amplitude, linear amplitude, standing-wave ratio, Smith chart etc With USB, GPIB, LAN and VGA English operation interfaces, 12.1 inch 1280*800 high-resolution multi-point touch screen Record/Run, one-button operation simplifies measurement setup and improves working efficiency Functions: Flexible calibration types, compatible with multiple calibration kits Techwin TW4650 series vector network analyzer can give you various calibration types, including guided calibration (auto cal), non-guided calibration (using mechanical cal kits for through response, through response and isolation calibration, single port calibration, enhanced response calibration, full dual-port SOLT calibration, TRL calibration), ECal. Different cal kits can be selected, like coaxial calibration kits or ECal kits, according to actual measurement needs, to make measurement easy for devices of diversified interfaces. â?¢ Multiple windows display all measurement channels The analyzer supports up to 64 channels and displays up to 32 measuring windows simultaneously, with up to 16 trace curves displayed in each window at the same time, allowing more visual observation and more convenient operation.
