About this app

Developer Description

miniVNA Antenna Analyzer

This application can be used to fully control a miniVNA Vector Network Analyzer. Your feedback is essential to make it better. Current version has the following features:

- fully control the data acquisition from a miniVNA, with or without the Extender;
- work over USB, bluetooth or WiFi (if available);
- can display reflection data in rectangular or Smith Chart mode;
- export data in CSV, ZPLOTS or S1P formats compatible with many existing applications;
- parameters that can be measured : SWR, |Z|, Return Loss, Phase, Rs, |Xs| for miniVNA and signed Xs for miniVNA Pro;
- you can select one of the predefined bands (all HAM bands), HF (0.1 – 30MHz), or a custom frequency interval (anywhere between the frequency range of the connected analyzer);

Frequency generator mode with the following features:
- 2 independent channels (for miniVNA pro) or 1 channel (for miniVNA standard or Tiny);
- normal or sweeper mode;
- independent attenuator control per each channel (from -60dB to 0dB), only for miniVNA Pro;
- adjustable phase difference between the channels (0-180 deg);

Cable data mode with the following features:
- cable length is measured in 2 steps, for a better precision (second step reduce the frequency interval);
- operate in meter or feet mode;

L,C,R,X-tal mode:
- measure x-tal resonance frequency and Q in manual or auto mode
- automatically measure inductors, capacitors and resistors

For the full list of features check included help or user guide available on my web site.

Thank you in advance for your feedback.

MiniVNA Tiny works as supposed with my Samsung Galaxy J5 over a standard OTG USB cable. No problems. Many thanks for this. I can't define the number of samples on the calibration though. I think it has a fixed number of cal points. (update 19/08/2016: I've noticed that there is some great discrepancy on the measurements between the Android Blue VNA and the desktop application vna/J 3.1.9. For example, the cable loss of a 0.5m RG58 at 144MHz is given as 0.6dB, while on the vna/J as 0.28dB, which is half of the BlueVNA calculation. I can, however, suspect that the limited cal points on the BlueVNA, compared with the 20000 cal points on the vna/J I used can be a reason for this difference.)

Used to work extremely well via bluetooth but now fails (unusable) with a lot of Java exceptions since phone upgraded to 6.0.1 - is this a known issue?
