Hi Regarding the manuals, I must look in my paper archive. I remember to have two manuals of two types of those "old test sets". I have even one of the test sets in my "museum". It will take a while to dig, as I am going to travel for 10 days. I will come back after that. Regards Bernd

I don't know how to use that particular Boonton unit. BUT... This is a different (more automated) unit which came maybe 10 years later. The guy does a good job showing how it works and uses it on real crystals: https://www.youtube.com/watch?v=y-rCgumTn4Q=youtu.be=4m37s Experimental Methods in RF

The DG8SAQ vector network analyzer has a built-in routine to characterize crystals. It may not be "correct" to simply plug them on port 1, but the results are quite reasonable. The right thing to sort out a bag of NOS crystals and finding the good ones or to get a somewhat realistic

Hi Gizmo’s like that were very common in the days before network analyzers became good enough to measure a crystal. They always were a troublesome item to keep running accurately. Without accuracy, their value was a bit limited. Every place I know of had a big drawer ( or cabinet ) of “magic
