nanoVNA vs SVA1015X VNA (Need entry level VNA)
<< < (7/14) > >>

OWO had talked about a new product with wider dynamic range.  It appears they released it but the cost is $800.   Again, I have no knowledge of the product.  It appears very similar to the V2Plus4.  Maybe following the Lite's lead to reach the 6GHz.  May be interesting to see some sort of shootout of all the sub $1000 VNAs from someone that actually knows what a VNA is.   Maybe we could talk Brian Walker into it!   May make for a good sales pitch for Copper Mountain.

Watching Brymen 869s multimeter tests on Joeqsmith Youtube channel I decided to buy this meter and I am very pleased. So I think you can rely on his opinion on LiteVNA.

 :-DD Don't say that!!  :-DD   It just seemed they were in a similar position as a friend of mine wanting to buy their first VNA without knowing the first thing about it.  That's what sent me down the NanoVNA path. 

I only suggest these low cost VNAs are a great educational tool because of the low risk.  I would still suggest if someone wanted to experiment below 300MHz, maybe learn about PDN measurements, work with very narrow band devices like crystal filters, the original NanoVNA makes a very good choice.  Worse case, your only out $50.   Your not going to ship an HP8753E for that.  :-DD

lol.  Forgot to finish my sentence.

I think that is a typical problem with not so professional products in this price range. It is too expensive to take a chance on and very few people buy it just for a review. Fortunately a -to me- local webshop ( Eleshop.nl ) also carries the LibreVNA so it is relatively easy for me to get one to try if/when I'm interested in buying one. If I don't like it, I can return it without hassle.

If you end up getting a loaner, consider making a review for it.   I'm surprised for the LibreVNA that they didn't consider sending them out for a reviews to stir up the interest.

Today I was reminded why you may want to consider a very low cost VNA like the NanoVNA to start out with.   Some time ago I produced a video attempting to show hams how not to blow up their NanoVNAs after seeing so many posts from them about how they damaged theirs.   Today I noticed this gem of a post.  They use a standard to drain down their antenna before connecting to the VNA.   Granted it's a $50 VNA and the standards (we use the term loosely) were included at that price.  IMO that is not a good excuse for such a poor practice.
