Seems like the "PicoVNA" was actually designed by LA Techniques
https://latechniques.net/products/Looks like PicoTech also rebadged their amazingly rudimentary GUI. This is really a show stopper for me... even with very good hardware specs.
The unit uses FTDI USB silicon.
See timestamp 51:00 of the PicoTech sales training video below for VNA market overview:
Tek seems to be price gouging as prices go up alot every year and they nickel/dime you to death on software "features" (for the RSA600 RT SAs anyways). The TTR supposedly also has substandard port matching and needs to make up for it during cal. Also it seems slow for the price. They repackaged the SRS SG390 w/ a graphics front panel for the TSG4100 and kicked the price way too much IMHO. So eh.... Tek is rubbing me the wrong way recently.
The MegiQ 6GHz unit does seem to only target the IoT craze, but their GUI is very nice, simple and effective. They look like a small team of engineers that are doing an offshoot product of what they needed to develop for IoT apps in their FT jobs.
http://www.codec-telecom.com/references_int.php#ToolsLooks like this team is trying to go FT with their new "startup"... so they are moving at snails pace... but their stuff does look very clean. They don't list real specs like dyn range, uncertainty, etc... so not really sure about the price tag on this type of introductory unit.
So not sure what to choose... the PicoVNA unit seems ideal, but need a real GUI like the MegiQ... still searching if anybody can provide it.. would rather not take on yet another project myself for this GUI.
