WHAT IS JNCRadio VNA 3G?

JNCRadio VNA 3G is a portable Vector Network Analyzer with frequency coverage 50k-3GHz. Its a more advanced product built on top of our first version, the NanoVNA-F V2. With a much more powerful processor and new firmware, it does not only look prettier, but –

1. Operating 4 more times faster – Scanning speed increased by 4 times to 400 points/s ;
2. Presenting more details of the measurement – Scanning points up to 501;
3. Saving more cals results –  Up to 13 calibration state storage slots;
4. Built-in RTC – snp files are named with RTC time, which is easy for viewing;
5. Further updates – More powerful processor makes the operation smoother and facilitates subsequent firmware upgrades to add more new features.

It is featured with a 4.3-inch IPS screen and a metal case, sweep speed running at 400 pts/s(4 times faster than our NanoVNA-F V2).

  • I’m interested in using the “JNCRadio VNA 3G” to measure the characteristics of an Xtal filter, but I’m concerned that the narrow bandwidth and small frequency step of the filter may not be compatible with the VNA 3G. The center frequency of my Xtal filter is below 60MHz. Would the VNA 3G be suitable for my needs?Yes, the VNA 3G would be able to measure your Xtal filter with a center frequency below 140MHz and a frequency step of less than 100Hz.
  • How do I pull traces, screenshots files from the VNA?On JNCRadio VNA 3G there are 2 ways to record the testing result, save the traces or perform a screenshot. Screenshots will be saved as image files, whereas trace data can be saved as .S1P file.Per screenshots, it can only be done from desktop software(You can’t do screenshots from the VNA itself).

    Per .S1P file, the trace data is saved in the VNA.(Either from VNA or desktop software). You can pull the .S1P file from the VNA once it is connected to a PC and recognized as an U-disk(Means not connected to the desktop software).

    To make the VNA an U-disk to the PC, check the user manual – the firmware upgrade section.

  • Why my boot up screen and the firmware loading screen come out scrambled, does it mean my device is defective?No worries this is a known case. The reason was that the clock of the bootloader was too fast and some screens couldn’t follow and showed scrambled information. The way to fix it is to update the bootloader but that’s not something an end user can do.However it doesn’t need to be fixed and It won’t affect any usages of the VNA.
  • Is there a Battery level indication?(YES for the latest firmware – v1.1.0) Battery level indication is now(firmware version 1.0.2 and previous) presented by voltage figures – lower than 3.4v to recharge is recommended, and lower than 3.2v devices will auto be turned off. This can be later changed to percentage in a later firmware upgrade.
  • How do you set the time from the front panel?RTC time needs to be set from the command line – there are instructions in the manual.(section – “7.2.26 rtc”)
  • What are the differences from the early version(f v2)?1.Scanning speed increased by 4 times to 400 points/s ;
    2.Scanning points up to 501, which will present more details of the measurement;
    3.Up to 13 calibration state storage slots;
    4.Snp files are named with RTC time, which is easy for viewing;
    5.More powerful processor makes the operation smoother and facilitates subsequent firmware upgrades to add more new features.
  • When in TDR what values are described by the scales on the sides of the screen?You can ignore those in TDR mode as the scale readings are not relevant.
  • Regarding calibration, I have not seen a way to enter calibration standards for the cal kit being used, directly into the 3G itself, ( I know this can be done when using NanoSaver ) is this correct?It is correct, the function currently is not supported.
