It seems that with DSO-2090 the only Record Length value that produces any output is Roll. And with that I can't set any meaningful samples/s and timebase values to see any low frequency signal, say 2kHz squares from the reference in the scope.

Attempts to change the Record Length value when the scope is running ends up with crash & segmentation failure with the following stack trace:
