V3 is a 6GHz Transmission/Reflection vector network analyzer, measuring the S11 Reflection coefficient and the S21 Transmission coefficient of a high frequency network; Not only testing standing wave impedance of the antenna, but also can debug the duplexer, the insertion loss of the filter, the isolation and testing the attenuation of the cable, shorten the coefficient, the phase, the amplification of the antenna amplifier Compared to the previous NanoVNAs (10KHz-1.5/3GHz), VNA6000 vector network analyzer provides a 50KHz-6GHz ultra-wide frequency range with an improved precision and accuration, Moreover, the System dynamic range for this VNA is up to 95dB dynamic range The upgraded vector network analyzer is contained with a 3200mAh/3.7V lithium rechargeable battery with loger operating time and lasting battery life. Also there are battery charge LED indicators at the back of the VNA which are the battery fuel gauge, that is closest to the CH1 port connector is the lowest charge level indicating 25% The vector network analyzer is equipped with S parameters export, Automatic continuous data acquisition, Custom calibration kit parameters along with support PC software control, like Windows(above 7), Linux, MacOS, the VNA can be more compatible with PC and antenna measurements, when measuring the frequency The Adjustable IFBW of the VNA600 enables optimal tradeoff between measurement speed and noise and can measure narrowband devices; Flip Display,For your using convenience, you can flip the display as the following steps: Menu - Display - Flip Display Color: silver material: metal Package Contents: 1 set spectrum analyzer Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
