About this deal

NanoVNA-H 4 includes a 4" TFT touch screen, with a simple interface that allows for measuring S-parameters (S11 and S21). My 'H' model was sold by a chap in Ky and it arrived VERY fast and the 'H' models have a plastic case. The firmware from DiSlord optimised user experiences and improved measurement speed, and alsoadded some useful automated measurement functions. In that case, my only criteria was firmware that didn't lock up requiring the VNA to be power cycled to recover.

Setting the center frequency to anything above 1Ghz, everything freezes and the only way to do anything turn off and back on again.

Just get a H4 from one of the official suppliers, for best results use it with the free Windows software.

Would you be so kind as to post a comparison of LiteVNA, NanoVNA-H4, NanoVNA-V2Plus4 and maybe some others in the frequency range 150kHz - 230 MHz? We can export Touchstone (snp) files for various radio design and simulation software through PC software. consider too that you may want it to run stand alone, or with one of the open sourced programs, which is not how I run them.

NanoVNASaver is a software that allows you to interface with the NanoVNA-H4 Vector Network Analyzer and conveniently manage the measurements and data on a computer. IMPROVED FREQUENCY ALGORITHM:The Vector Network Analyzer can use the old harmonic extension of si5351 to support the measurement frequency up to 1. Power off the NanoVNA-H4: Once you have completed your measurements, press and hold the power button for a few seconds to turn off the device. Hugen’s NanoVNA-H improved NanoVNA with a 5V DC-DC boost converter, which enables stable operation driven solely by a 3.

Supplied with: 1 NanoVNA-H or Nanovna-H4, with calibration kit, 1 50Ω SMA dummy load, 1 SMA open circuit, 1 SMA short circuit, 1 USB Type-C power cable, 2 SMA Male RG316 15cm cables, 1 SMA female - SMA female adapter. A portion of all proceeds of this VNA is paid to the ttrftech team to continue and further NanoVNA development. 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. Connect the antenna or transmission line: After calibration, connect the antenna or the transmission line you want to measure to Port 1 (CH0) using a suitable adapter, if needed.Took a gamble with this (bit more expensive than direct from China, but got it next day, no customs, etc), and as you can see from the photo's it looks as genuine as they come. Reviews of equipment capable of CB/Freeband operation or not FCC Certified/Type Accepted may be removed. Measuring the Standing Wave Ratio (SWR) on a NanoVNA-H4 Vector Network Analyzer is a straightforward process. Calibrate the NanoVNA-H4: Before making any measurements, it is essential to calibrate the device to ensure accurate results. Still, be advised: this is a Japanese PhD student's hobby project, then cloned by a Chinese manufacturer who will provide absolutely no support nor fixes.
