Note, though, that any frequency measurement using something other than
a scope relies heavily on assumptions about waveform.  When I first got
my current scope, I hoked up a little audio-frequency square-wave generator
with a 555 as an independent test signal.  I was a bit surprised to find
that my frequency counter read twice what the scope showed me.  Turned
out that the leading edge was sloppy enough to double-trigger my rather
sensitive frequency counter.  There is no substitute for seeing exactly
what's happening.
