does, and should also work the same way for your application. So if
you need the clock output, the BasicRX is a better choice.

And, as a follow-up, you might need to muck with the appropriate UHD
driver to get it to enable those clock pins,and drive them at a suitable
rate.
You will likely have to "crib" from the drivers for cards that require a
refclock--like, well, all of them *except* for BASIC_* and LF_*.
In fact, it might be reasonable to suggest that there be an option in
the standard drivers to enable those pins at a default rate of 10Mhz or
something
for the BASIC_* cards. Or some easily-usable API frob to do so.
