UPGRADED NANOVNA ANALYZER: SeeSii Nanovna-h4 Vector Network Analyzer is developed by Hugen. With latest 4.3 version, 10KHz- 1.5GH z measure range, 4.0 inch LCD touchscreen, mini and portable design. This Antenna Analyzer is provides outstanding vector network measurement capabilities and perfect for evaluating antenna resonance and SWR. It is a very handy & smart analyzer for electronics engineer, amateur radio operators or radio diy amateurs.
BUILT-IN MICRO-SD PORT & TIME DISPLAY: The lastest antenna analyzer with MicroSD card port, so you can save field test data or screens to a MicroSD card at any time, support up to 32GB memory card. (Not include in the pacakge). In addition, different from old version NanoVNAs, the date and time can be customized, which is convenient for you to further record and save data.. The default firmware main function is used for antenna performance measurement.
IMPROVED FREQUENCY ALGORITHM: The Vector Network Analyzer can use the old harmonic extension of si5351 to support the measurement frequency up to 1.5GH z. 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- 1.5GH z band is better than 40dB of dynamics. Great for trouble shooting antennas and improving performance.
PC CONNECTION & TX/RX FUNCTION: The vna analyzer uses PC software NanoVNA
Saver, it can connect to a NanoVNA and extracts the data for display on a computer for saving to Touchstone files. We can export Touchstone (snp) files for various radio design and simulation software through PC software. In addition, the default firmware is mainly used for antenna performance measurement. The TX/RX method can measure the complete S11/S21 parameters (need to manually replace the transceiver port wiring).
Abundant Accessories: Equipped with 1x NanoVNA-H4(with 1950mA-h battery), 1x USB Type-C cable, 2 x 15cm SMA male to male RG316 RF cable, 1x SMA male calibration kit - OPEN, 1x SMA male calibration kit - SHORT, 1 x SMA male calibration kit - LOAD, 1 x Touchscreen pen. It's very useful as an antenna analyzer for your ham station, easy to set without fancy calibration.
Note: The function of the versions 4.2 / 4.3 is the same, it will be shipped randomly.
