I would use some signal generator to generate a tunable sinusoid and
feed this to the quartz with the testing circuit from the standard
setup (see eg [1]) and measure the power on both sides of the quartz,
like in an VNA setup. You will probably not need the phase information,
so a simple power detector would be enough.
Bernd should be able to tell you way more about this than I can.
