Blue VNA

Blue VNA


This application can be used to fully control a miniVNA Vector Network Analyzer. Is still in beta so 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);
- support for all Smartphones and Tablets with a resolution higher than 320x240, based on Android version 2.2 or higher;
- can display reflection data in rectangular or Smith Chart mode;
- intuitive and wizard based calibration interface to speed up the calibration procedure;
- calibration data is saved in the configuration file for each mode (Antenna/Transmission/Frequency), so no need to repeat the procedure each time you start the application;
- if no calibration data is available at startup, calibration procedure is initiated automatically;
- offline mode support allows you to load and/or save vectorial data without connecting to a miniVNA. This mode can be used to play with all the features available for both Standard and Pro versions. Some sample files are included in the package;
- internal Smartphone memory is used if no SD card available;
- export data in CSV, ZPLOTS or S1P formats compatible with many existing applications;
- save PNG screenshots;
- demo capture file included to be able to play with the application even without a VNA;
- virtual LED to display current connection mode: BLUE – Bluetooth connected, YELLOW – BT connection in process, RED – Error connecting over Bluetooth, GREEN – Offline Mode;
- automatically enter Offline Mode at startup if Bluetooth is disabled;
- antenna (reflection) and Transmission modes support with the following features:
- gesture (Multi Touch) support for horizontal zoom and frequency shift without a new capture;
- 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);
- select parameter to display (using different colors);
- an on screen marker can be activated / deactivated and freely moved by dragging it around the screen;
- display all the parameters values at the marker position (only the ones you manually selected);

Frequency generator mode with the following features:
- 2 independent channels (for miniVNA pro) or 1 channel (for miniVNA standard);
- 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);
- extremely easy AND intuitive operation, even with small screen devices;
- possibility to manually enter the frequency through a numeric keypad;
- working in manual frequency set OR continuous (live) mode;
- rotary knob to change parameters in both manual or live modes. The knob provides acceleration;
- lock mode to prevent accidentally settings changes;
- frequency calibration can be done in a very intuitive mode from Generator mode.

Cable data mode with the following features:
- background control graphs for Phase and Loss, calculation is done automatically;
- just connect the cable to be measured at the DUT connector with the other end open;
- include a list of well-known coax cables and their Velocity Factor;
- measure and calculate cable length from less than 1m to hundreds of meters;
- cable length is measured in 2 steps, for a better precision (second step reduce the frequency interval);
- operate in meter or feet mode;
- measure cable loss for different frequencies from 0.1 To 180/200 MHz;
- can work in Offline mode, if the cable was measured before and data saved in a file.

X-tal mode:
- measure resonance frequency, R and Q in manual or auto mode

More details are available in the included help or on my web site.

Thank you in advance for your feedback.

Recent changes:
New in 0.9.4-3 from 0.9.4:
- display fw version, batt voltage and internal temperature for Tiny mode in startup page
- better interpolation for calibration data - less capture "noise".
- change antenna bandwidth calculation (delta F) for SWR = 3 instead of SWR = 2
- replace WiFi by NET as you can connect over 3G/VPN too
- add 23cm and 13cm bands in Tiny mode
- bigger fonts in file list
- solved several bugsin Tiny mode

Mini-VNA and Galaxy Note 8000 or Galaxy S1 phone Very good tool and well designed. It was not working with an older firmware version of mini-VNA (2.1) but now, after I did the firmware upgrade to the latest version (2.6), it is working. Thank you Dan for this unique tool.

blue vna This is great software I am using my Toshiba tablet working great. Did start out with the tablet now finding the device,found blue tooth but that was it . After a wile playing around with it. It hit me I had to update the minivna with the newest FW after the update we were up and running. This is a great product I would recommend it to all Hams. Hocked to my antenna tuner via a switch, makes it a snap to tune my antenna to the best swr.. Thanks again Dan for this great software..
