Brooke - In that case why do not just use a signal generator like an 8640B with the crystal in series with the hot lead and then the other side of the crystal terminated in 1K or so. Then you can put a scope across the 1K resistor and watch the scope as you tune across the suspected resonant frequency. I have done this a lot when I was not sure of the crystal frequency, or, if it was working or not. Real simple to do. If all else fails, I am sure I have the QST you mentioned, and could scan the relevant pages for you. I also have a military crystal activity meter that does do a full characterization, but, it is big and bulky, and, I hardly ever use it. 73 & Merry Christmas - Mike

This is more related to knowing if a given crystal is alive than characterizing it, i.e. a Crystal Activity Meter type thing.
