The SDR-Kits software is more refined.? Their calibration kits are of higher mechanical and electrical quality.
I use it for things like sorting crystals for ladder crystal filters and LF/HF tasks.
I find it more convenient than the HP 3577A (5 Hz - 200 MHz) in many cases.
The HP 8702B (a 3 GHz 8753C with the word optical in the description and a slightly different ROM set) compares favorably with the 0-3 GHz specifications of the LibreVNA.? The HP wins in the software capabilities and interface.
I am currently using the LibreVNA from 2-6 GHz along with HP 8595E/8596E and a DS Systems tracking generator.? The LibreVNA came with better quality cabling and calibration kit than the NanoVNA variants I have.
John, contact me if you are still looking for a SDR-Kits VNWA 3 to borrow.

I have a variety of VNA's available but am lacking the SDR-Kits model. Wouldn't it be nice if we knew where it stood compared to the newer nanoVNA's costing a fraction of the price for the same dynamic range and a higher upper frequency limit?
Also, how do the hobby VNA's compare to lab-grade VNA's at HF and up to 1.2 GHz?
If you own an SDR-Kits VNA, can do without it for 3 weeks and trust me to return it to you, please see my offer here:
