Nobody uses a frequency counter any more.

Why not set a multifunction counter up for a start/stop period 
measurement...then if you can talk to it over any interface bus, let 
that puppy, the microcontroller circuit, run and log the time periods to 
run the routine.  After a while, take an average.  If you have an el 
spiffo counter, you can program that to do the averaging too.
