<div dir="ltr">I can't speak for others. I've been successful in early prototyping using one for simplistic off-diagonal h-matrix testing, i.e. varying the h-matrix condition numbers.

integrating our software control with any of them. To date, not many of our customers<br>
have been interested in this, so it did not seem worth the effort.<br>

Do you see this as being useful for normal AP vendors/users, or mostly just radio manufacturers such<br>
as BCM?<br>
<br>
In case someone has one of these that has a sane API, I'd consider adding automation support<br>
to drive it while running throughput or RvR or whatever other types of tests seem interesting.<br>
