Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•【Upgraded NanoVNA SAA-2N Version】Not only testing standing wave impedance of the antenna, can also 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.4.0 inch touch screen make it easier for you to read data and test
•【Calibration 】The SAA-2N/NanoVNA_V2.2 does not load the initial calibration data at startup, and does not automatically interpolate the calibration data after the user changes the frequency, and must recalibrate or recall the calibration data (previously saved data) after each startup and frequency change. Please read the user manual carefully before use to avoid damaging the device.
•【 Improved Performance】High stability, high sensitivity, high precision, improved performance.Made of high-quality aluminum protective case, strong practicability and long service life.Bulit-in 3000mAh rechargeable battery,USB powered
