It would really help in a comparison to show a post test spreadsheet actually comparing the two devices. Are they 1%, 5% or 20% different? The reason I ask is that if you are trying to use it for real analysis and you need specific results to build or analyze a unit under test then you begin to understand the reason that the HP is (was) so expensive. Most of us don't have access to the high end TE and would love to know the actual usefulness/accuracy of the NANO VNA (I have one on order, should be here in about a week). Thanks K7HIL
The quality of these VNA's are a bit hit or miss. My one arrived yesterday and the touch screen is dead, the menu rocker works 50% I was excited to begin measuring my antennas, but that will need to wait till the replacement arrives. If you get a good one, you've scored big time!
Well done! I really like your content! I have also done my tests with a SA with TG configured as scalar analyser (ua-cam.com/video/K41O-_5DmEo/v-deo.html) and the nanoVNA showed the same LogMag data. I also manually checked "by hand" at low frequencies that the phase information is correct. However it would be nice to see a comparison with a real VA to appreciate why the cost so much more than the Nano :) thanks! Keep up the great work!
@@IMSAIGuy thanks, that would be awesome to see. But I'd like to see/learn about some (high precision) measurements on low frequencies (where the NanoVNA can operate properly, say up to 300mhz) which give good insights on a HP VNA but bad ones on the nanoVNA. Not that I could afford any real VNA any time soon, anyway! :P
@@therfnoob7697 I do plan to do that. It should be pretty good maybe better than the big VNA at low frequencies since it uses bridges instead of couplers. The only difference I expect is the noise floor (dynamic range). It should accurate on frequency and phase. Phase at 18GHz is where the expensive ones earn their keep. and why the cal standards are so expensive
Thanks for the quick comparison. It's exciting all the equipment that's becoming so accessible. Looking forward to your shootout with an HP VNA.

NanoVNA V2 is very comparable to a high end spectrum analyzer! Nice comparison video.

you should have calibrated with the clip leads
With "F" connectors it's 72 ohm, put a 22 ohm resistor on both ends and test again.
Too bad i can't test the IF filters in my HF receivers with this device...
It has came out a new nanoVNA now version 2 that goes up to 3 GHz , have you seen or tested that version, or any plan to do in future ?
Buy me one and I'll do tests

My friend has a real HP VNA at home. Once the restrictions are off I plan to do a shoot off. Of course he's goes to 18GHz

@@IMSAIGuy thanks IMSAI guy! I look forward your next video.
