What is a VNA?

• A VNA is a form of RF network analyzer widely used for RF design applications.
• A VNA may also be called a gain-phase meter or an automatic network analyzer.
• An SNA is functionally identical to a spectrum analyzer in combination with a tracking generator.
• Vector Network Analyzer measures both amplitude and phase properties

Short list of Tips

• Allow 20 minutes for the miniVNA Tiny to warm up for best results
• RL is S11 (return Loss), TL is S21 (Transmission loss)
• Low power out of the DUT port can be limiting
• There is no ability to control the power output level of the DUT port
• 0 - 1.5 GHz is more accurate than 1.5 to 3GHz
• It reaches more than 50 degrees, and should be calibrated at that temperature, NOT when it is cold!
  For more accurate results let the Tiny warm up for a half an hour and re-calibrate on each powerup.
• Do not leave a piece of coax on the (DET) Detector port. If you do it seems to affect the readings
  in reflection , itcan be solved with the use of chokes.

Install Java on Ubuntu 18.04

Make sure only one copy of the application is running, otherwise the port will appear locked. The first to run will have access to the port and the other invocation will not alow the "setup" option to access the port.

Also make use you are part of the dialout group and that the port has dialout permissions.
