Also, people have to understand that measurements over 3GHz require very expensive accessories and cables to get any meaningful measurement. I would spend my hobby money on such a device (after saving up money for it), but I would not consider spending 1/3 of that money for a NanoVNA.

While it only goes up to 3.2GHz, it is an entry level professional equipment. The thing is: for 1500 Euro you get a Siglent SSA3021X which you can hack into a SVA1032. At 500 Euro, I think that there will be much less hobbyist people like myself buying one for no particular or specific application other than basically trying it out and learning from it. That is play money for me that I can use to get these device for the sole purpose of learning how to use it and understanding what (in this case) a VNA measurement is. Īs hobbyist I bought the 50 Euro NanoVNA (probably a clone of it). If there are problems that the seller covers them or the unit is returned. If you go this route, and your planning to layout a bit of cash, you may want to work a deal where the unit is sent directly to the manufacture for a checkout and any updates. Maybe with the current state of things, you could find a really good deal. Of course there is the used market as well. That may be a really good option if your in a hurry, need a working system and are short on funds. You may also be able to rent a system for a few months. You can download the software for the ones linked below and see if you like how they drive. There was one from Russia but again, poor specs and it looked like there was no remote control. The performance was too poor for what I was wanting it for anyway. At $400 a pop, for the privilege of help them develop it and having to deal with the censorship, I lost interest and have no idea what's going on with it anymore. Last I saw it seemed they were having a lot of problems and were getting ready to turn a new hardware revision.

I tried to as a few questions on their forum a few times but they censored everything. A few people asked me about porting my software to run on it. I had been following the LibreVNA for a long time. My interest was personal use so I can afford to wait forever.

Which nanovna to buy
