Bandwidth is traded for latency. The sharper the bandwidth, the more
processing time that is taken, thus increasing latency. Also slop
factor on the DSP filters affects latency. The steeper the filter
skirts, the more processing time is needed thus also increasing latency.
Dynamic range is all about the maximum voltage range that the DSP front
end can handle before it goes into saturation.

Dear Rick-
I am still learning about this DSP stuff but I believe the bandwidth may be
traded in processing
for dynamic range with the rule of thumb being 3dB each time the bandwidth
is halved. We are
starting with 56MHz bandwidth.
It will be fun to play with. I am messing around with a nine dollar 8bit
DVT-B dongle for now.
Much cheaper to learn on!
