they spec 4 bits of resolution with either a 10MHz or 100kHz clock but never state what the exact possible sample rates actually are

Hi ,
The 4 bit resolution means that you can scale the base clocks on your 6052 E by an integer value that goes from 1 to 2^4.

Hi pn2543-
The 4-bit resolution specification you mention refers to a 4-bit frequency divider onboard the device that can be used for pulse-train generation, using the 10MHz or 100kHz timebases on the board.  In NI-DAQmx, this output is referred to as "freqOut".
The analog input sampling rate is actually determined as 24-bit divisions of the 20MHz (or 100kHz timebase, if needed) on the device.  The maximum sample rate is 500kS/sec for single channel according to the specs, and the minimum would thus be 100k / (2^24-1) = 0.00596 S/sec.
Hopefully this helps-
