I'm one of those who question the usefulness of the frequency counter. I use
a musical tuner, sine wave generator, scope (lissajous)... and my ears as a final

QC check.

I set the sine wave generator to a midrange reference frequency. Use the Tuner to
check
the reference... then use the lissajous patterns to take it from there.  The
lissajous patterns
are very similar to a strobe tuner... it is a matter of pattern recognition from
then on.

I think that freq counters are too hard to intrepret (sure they're OK for A=440).
And too
slow to settle to reasonable precision.

oh... and mine is broken :^P

I would like a frequency counter to determine the linearity of an unknown VCO
design... lissajous
patterns don't help much.
