I plan on using it in a Colpitts SAW oscillator. So it is kind of
determining the oscillator's frequency, but only approximately. The SAW
resonator will determine the frequency.

I probably can't spend the time to learn how to use that tool, even though
I could probably do something useful in the 30-day evaluation period :)

Good idea, this.

Ah, thanks, this looks like it's worth a shot.

Maybe I just buy a kit of nH inductors... :)
