There is an older version for the ZCU111 that should be available on my web site. It's also free for academic users, although it doesn't currently say that.
I have a newer version for the ZCU111 that supports variable sampling rates, but it hasn't been released. That's also true of ZCU208, HTG-ZRF8-Rev1, HTG-ZRF8-Rev2, And HTG-ZRF-HH.
