【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. 【NanoVNA-H4 HW V4.3】ZNZHNSI NanoVNA-H4 Vector Network Analyzer is a Hugen Origin product that provides complete vector network measurement functions, this antenna analyzer adopts the latest version 4.3, 10KHz-1.5GHz measurement range, 4.0 inch LCD touch screen, mini portable design. [Improved Frequency Algorithm] The improved frequency algorithm of NanoVNA-H4 supports measurement frequencies up to 1.5GHz using the odd harmonic extension of si5351. The extended 300M-900MHz band provides over 60dB dynamic range, and the 900M-1.5GHz band provides over 40dB dynamic range. 【PC Connection and TX/RX Function】: Using the PC software NanoVNASaver, you can connect the NanoVNA-H4 antenna analyzer to NanoVNA and extract the data for display on your computer or save as a touchstone file. Equipped with a MicroSD card port (supports memory cards up to 32GB), you can save measurement data and screenshots at any time. TX/RX method can measure complete S11/S21 parameters (requires manual modification of transceiver port wiring) [Antenna performance measurement] The default firmware of NanoVNA-H4 Vector Network Analyzer is mainly used for antenna performance measurement. The TX/RX method can measure complete S11 and S21 parameters. If S12 and S22 parameters are required, the transceiver port wiring must be changed manually. NanoVNA-H4-FBA
