I'm at home where I only have an analog tektronix 2213 60MHz scope (no
spectrum analyzer). How can I measure the frequency deviation / pull of
the crystal with the series configuration? Any ideas?
If you have another crystal, build a second oscillator. Run the two into
a mixer followed by a simple lowpass filter, and measure the resulting
difference frequency.
