> The RFsoC 4x2 board has 4x RF ADCs (5 GSPS) and 2x RF DACs (9.85 GSPS)
is like chasing after a fly with a sledgehammer. It wildly over-specs something that is almost completely useless for the task at hand (real time bandwidth, mass of hammer) while it wildly under-specs the important parts (frequency range, directivity, agility of hammer).
If you're doing modern wireless systems measurement and testing (4G/5G) most likely you will need spectrum analyzer (SA), vector signal analyzer (VSA) and vector signal generator (VSG).
The cost of all the disparate systems namely VNA + SA + VSA + VSG will easily cost north of USD100K for the used ones and multiple times more for the new ones. With the low cost RFSoC platform together with the standard RF test kit (attenuater, pre-amp, multiplexer, switch, etc) you are pretty good to go.
It's really perplexing that no one including the Chinese are trying to disrupt this industry, Keysight and R&S are currently charging arms and legs for their equipments even the basic one like VNA.
No point.
1) Low volumes
These things never really go obsolete and the replacement rates are abysmal.
2) Race to the bottom
Once you disrupt it, everybody sees that you disrupted it, and everybody clones you and piles in.
Customer support is the only differentiator. To fund that, you have to charge north of $10K per unit--generally north of $25K.
Tektronix found this out the hard way with their real time spectrum analyzers. It was a nice disruption at the $5K point. Lots of people bought them. Then demand dropped like a rock because everybody who needed one bought one. And because the revenue crashed Tektronix laid off the development group--who are also the same people you need for advanced customer support.
