VNA program problem

Post by DD4WH » Wed Aug 30, 2017 11:08 am

Hi Pavel and all other VNA interested!

I began using the Red Pitaya as a VNA to measure frequency response of a homebrew bandpass filter.

I use OS 097.560 and obtained the VNA App from market place (094.1451)

That works and the RP goes into VNA mode.

Then I start the vna.exe - application (Windows 8.1) downloaded from here:

The file for download is called I extracted it into a local folder and started the vna.exe file from that local folder.

However, the VNA won´t work: I can change the IP adress and connect to the RP successfully, but whenever I try to sweep (pressing on LOAD, SHORT, OPEN or DUT) a small "Sweep status" window opens and the program gets stuck. I also changed bandwidth and no. of points which sometimes allows the sweep status to reach some percentage ("Sweep status"), but it never succeeds.

Am I doing something wrong here?

All the best, Frank DD4WH
