My review for the NanoVNA V2 Plus 4

Nice feature! Thank you!
Interesting new features, I'm just starting to get an understanding of this software, Thanks for sharing.
Thanks you, as always an informative video.
Dislord, who maintains the firmware for the LiteVNA, chimed in. This prompted me to run a few tests. Not sure if we learned anything from it but you are welcome to follow along at: www.eevblog.com/forum/rf-microwave/nanovna-custom-software/msg3974300/#msg3974300
Will you be releasing your software for the Lite too? Thanks
The Lite uses the same protocol at the V2Plus4. Dislord had performed some tests with it. Of course, there are also the open sourced applications as well if you are looking for something quick.
@@joesmith-je3tq ok did not see that yet, I will see if I get it running, your software is so much more useful and better than anything else out there, thanks
but sure, I'm not in a hurry, I forgot to add
@@heinrichhein2605 The only problem I saw was when running the Lite at very low frequencies, my current release would time out. Dislord had talked about trying to speed this up and it may not be a problem now. I doubt many users would be experimenting down that low anyway.
I haven't tried any of the other software except the QT, which never worked with my PC.
MAKE SURE YOU READ THE README BEFORE DOING ANYTHING ELSE.
Here is just one example of how not following the instructions can waste a lot of time.

The LiteVNA is now half the price of the V2PLUS4. Are the functionalities comparable? Which is the better choice to buy?
Well Jeff, I'm not sure. If you want to do narrow band work, say make your own crystal filters. Then I would say the original NanoVNA. If you want to play around with PDN measurements, again, I would say the original NanoVNA. I never found the H4's firmware to be good enough to use but the hardware would have made it a slightly better choice for this application. Working above 300MHz, the Lite and V2Plus4 are the way to go. Above 3GHz, the Lite. Below 3GHz, pick your poison. They both have their positive and negatives. For learning, all of them are great! They are cheap, so if you do something stupid, it's not going to break the bank to replace it.
I got the original and the v2plus4. Having good coverage at lower frequencies and being able to compare measurements from two devices were plusses for this newbie's learning. Higher frequency work is not important, though I push it to the limits(beyond?) to see what happens.
The internal AVG is actually setting the RBW. That is why the noise goes down with increasing AVG

I was currious if you could review the AEMC MTX 3293B multimeter.
I would certainly consider it. Do you currently own one?
@@joesmith-je3tq no, but I would like to buy it.
@@BogdanO45 I've added it to the list. Eventually, I'll run a run another poll of the meters people want to see.
