Features:This Nano VNA is a DIY product that provides perfect vector network measurement capabilities, tiny and handheld, stand-alone with 4-inch LCD display, portable with 1950mAh battery powered or USB powered.The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 1.5GHz. The 50K-300MHz frequency range of the si5351 direct output provides better than 70dB dynamic, The extended 300M-900MHz band provides better than 60dB of dynamics, and the 900M-1.5GHz band is better than 40dB of dynamics.The default firmware main function is used for antenna performance measurement. The TX/RX method can measure the complete S11 and S21 parameters. If you need to obtain S12 and S22, you need to manually replace the transceiver port wiringUsing PC software NanoVNASaver, it can connect to a NanoVNA and extracts the data for display on a computer, and for saving to Touchstone files. We can export Touchstone (snp) files for various radio design and simulation software through PC softwareThe metal shield is designed to reduce the external interference and improve the measurement accuracy.Sprcifiactions:ABS case: 75mm x 133mm x 18mm (excluding protrusions)Measurement frequency: 10KHz -1.5GHzHW version：4.3RF output: 0dbm (±2dbm)Measurement range: 70dB (50kHz-300MHz), 60dB (300M-900MHz), 40dB(0.9G-1.5GHz));There may be errors caused by nonlinear transformation of fundamental wave when using harmonic measurement.Port SWR: < 1.1Display: 3.95 inch TFT (320 x 480)USB interface: USB type-C communication mode: CDC (serial)Power: USB 5V 200mA, built-in 1950mAh battery, maximum charging current 1ANumber of scanning points: 101 (fixed)Display Tracking: 4, Marking: 4, Setting Save: 5Frequency Tolerance:<2.5ppmFrequency Stability:<0.5ppmPackage List:1X NanoVNA-H4 (with 1950mAh battery)1X USB Type-C data cable1X Type-C To Type-C cable2X 15cm SMA male to male RG316 RF cable1X SMA male calibration kit - OPEN1X SMA male calibration kit - SHORT1X SMA male calibration kit - LOAD
