Technical description JNCRADIO VNA 3G

The JNCRADIO VNA 3G is a continued development of the well-known NanoVNA analyser. The analyser uses a robust aluminium housing, the 4.3" IPS LC display (800 x 480 px) offers a wider viewing angle and better brightness, which improves readability even in bright sunlight.


In contrast to its predecessor NanoVNA-V2, the JNCRADIO-VNA-3G uses a faster processor and more memory.
The main improvements are:

  • Faster sampling, up to 400 points/s
  • 501 sampling points
  • 13 memory locations for calibration data
  • Built-in clock, allows file names with time of day
  • More space and performance for future updates


Two SMA sockets are available for measuring the S-parameters S11 and S21. This allows reflection and transmission measurements, i.e. measurement of impedance, SWR, attenuation, matching, cable length and much more. The maximum output power depends on the frequency and is between -14 and -9dBm.  The dynamic range for reflection measurements (S11) is 70 dB or better up to 1.5 GHz and 60 dB or better in the range from 1.5 to 3 GHz. This is more than sufficient to perform the usual tests such as SWR, impedance etc. with good accuracy.

The JNCRADIO VNA 3G has a built-in 5000 mAh battery. The battery is charged via a USB-C socket with max. 2A, depending on the power supply unit (not included). A full charge is sufficient for approx. 7 hours of operation. With the built-in USB-A socket, the JNCRADIO VNA 3G can also serve as a power source (powerbank function) with 5V/1A.

Application description JNCRADIO VNA 3G

An HF network analyser should not be missing from any measuring station, regardless of whether you are dealing with radios or antennas. Progress in semiconductor technology has led to the availability of very inexpensive measuring equipment that used to cost well over 10,000 euros. This is especially true for the NanoVNA, a vector network analyser that allows very versatile measurements on RF devices, cables and antennas.

This makes it easy to measure the most important properties of antennas, filters, cables, oscillating circuits and other assemblies. The two ports of the analyser offer measurement possibilities of the scattering parameters S11 and S21 (or S12 and S22), i.e. measurement of the reflection at one port (S11) and the transmission from port 1 to port 2 (S21). For higher accuracy, this measurement process must be calibrated. A calibration set (Open, Short, Load, 2 measuring cables) is included. The JNCRADIO VNA 3G offers memory for up to 13 calibrations that can be reused under the same measuring conditions.

Operation is via the colour LC display (touch display) and three buttons on the side. The menu is logically structured and allows operation without a manual after a short training period. Free software is available for operation together with a Windows PC.

The NanoVNA is an open source project that has been copied many times. Version 2 has been improved in many parameters, and the software for it is constantly being further developed. As usual with open source projects, there are many providers of similar devices. The device offered here by WiMo comes from a company with high quality standards and good service, with whom we have had good experience for many years. Advantages of buying the NanoVNA from WiMo: * fast delivery from Germany under European legal conditions * reliable service in case of failure * accessible support for technical questions
