Update: Following on from Arie¡¯s email I found that the display was set to manual axes and once setting it to automatic on both axes the data is now being shown correctly.

Thanks for the tip off Arie! Larry - I am going to follow up on your suggestion and investigate the alternative software. I really only got the nanovna-H4 for its TDR measurement which annoyingly is not available on my Rigol DSA-815TG VNA but I am delighted with the ease of use of the nanovna-H4 - especially standalone for in the field measurements. One thing I have yet to investigate is the use of averaging to improve the dynamic range and ability to see a deep notch in a cavity duplex filter but by all accounts it won¡¯t go down to -110db. Maybe a future hardware version will have less phase noise and higher output level and input pre-amplifier for this application but I¡¯m sure it will come at a higher price level owing to the design challenge. I am very pleased with the nanovna and really appreciate the ongoing work of the HW, SW and FW developers of this little marvel as well as the help available on the forum.
