About this app

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.

Ratings and reviews

Although the app crashes setting a custom frequency range in the Smith Chart mode, one can set a custom frequency range in the graph mode. If then the user wants to view Smith Chart results, he can simply switch back to Smith Chart mode and retain the custom freq range. This is a satisfactory work around. My only other ask would be to permit an averaging mode in the Smith Chart view, where the analyzer will measure over a period of time over the custom frequency range.

Updating this review after I couldn't connect via Bluetooth. Enabled location services and worked fine

Hi Dan .. Question: Should this work with the VNAmini pro plus2 (the red one with aluminum case) ..
