Today we are checking out the NanoVNA-H4 analyzer. This little gem does a lot more than just SWR, so check out this video and other videos on YouTube to see all about it.
- This NanoVNA-H4 with 4inch LCD Touchscreen, Portable with 1950mAh battery rechargeabe powered or USB powered. Can last longer working time.
- The Vector Network Analyzer 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.
- This Antenna Analyzer is a DIY product that provides perfect vector network measurement capabilities, tiny and handheld.The default firmware main function is used for antenna performance measurement. The TX/RX method can measure the complete S11 and S21 parameters (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. Use strong and secure power supply at the same time. Enhanced performance in all aspects
