The 3GHz second-generation vector network analyzer is based on OwOComm's SAA-2 design, and its performance has been greatly upgraded. Compared with the basic SAA-2, SAA-V2 adopts a metal shell design, the screen size increases from 2.8 inches to 3.2 inches, and it also adds functions of measuring duplexers, filters, S parameters, and voltage standing wave ratio. It can test the standing wave impedance of the antenna and debug the duplexer filter insertion loss and isolation standing wave. It can also test the cable attenuation shortening factor phase. It can also test the amplification factor of the antenna amplifier and has the powerful function of frequency meter. Metal shell, screen touch is more accurate, easy to operate, no need to connect to power supply, not bound by data cable, can be used as a stand-alone machine. It can also measure duplexer measurement filters (currently, except for this model, other products cannot do such a powerful function) POWERFUL FREQUENCY METER: Improved frequency measurement can measure antenna frequencies from 2.4G to 3G. 70dB (50KHz-1.5GHz), 60dB (1.5GHz-3GHz). Reflection measurement S11: 50dB (50KHz-1.5GHz), 40dB (1.5GHz-3GHz); Antenna analyzer: 1.005 (50KHz - 1.5GHz), 1.02 (1.5GHz-3GHz) Compatible: The 3GHz second-generation vector network analyzer is based on OwOComm's SAA-2 design, and its performance has been greatly upgraded. Can be controlled via PC, computer software compatible with Linux, Windows (7+) Colour:black Material:Aluminum alloy Package Contents: 2 x SS405 double male pin 30cm 1 x Calibration piece 50 ohm load 1 x x Calibration parts short circuit 1 x x Calibration piece circuit opener 1 x SMA female socket double way 1 x USB data cable 1 x 3.2 inch touch screen V2 host 1 x English operating instructions 1 x touch pen Only the above package content, other products are not included.
