NanoVNA-H NanoVNA-H4 Vector Network Analyzer 10KHz-1.5GHz MF HF VHF UHF Antenna Analyzer Antenna Tuner Nano VNA SWR Phase Delay

Seesii NanoVNA-H & NanoVNA-H4 Vector Network Analyzer 10KHz-1.5GHz MF HF VHF UHF Antenna Analyzer Antenna Tuner nano vna SWR Phase Delay

NanoVNA-H Option

Features:

Upgraded Nanovna-H HW3.6: SeeSii Nanovna-H Vector Network Analyzer is developed by Hugen. With latest 3.6 version,10KHz-1.5GHz measure range,2.8 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 mini handy & smart analyzer for electronics engineer, amateur radio operators or radio diy amateurs

Improved Frequency Algorithm: The enhanced frequency algorithm uses the odd harmonic extension of the si5351, supporting measurements up to 1.5GHz. The metal shield reduces external interference, improving accuracy. The si5351 direct output offers 70dB dynamic range (50K-300MHz), 60dB (300M-900MHz), and 40dB (900M-1.5GHz). The default firmware supports antenna performance measurement

Multi TX/RX Function: 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)

Android and PC Software Control: The NanoVNA analyzer uses NanoVNASaver software, which connects to the device, extracts data, and saves it in Touchstone format for display on a computer

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

NanoVNA-H4 Option

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 wiring

Using 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 software

The metal shield is designed to reduce the external interference and improve the measurement accuracy.
