Congratulations.  You just measured the frequency of the crystal inside your 
53131A.

Stand on your head and it will make sense.  If you feed an unknown signal in, 
you can measure its frequency.  But that's only as accurate as the internal 
clock.  If you know the frequency of the external signal more accurately than 
the internal clock you end up measuring the internal clock.
