[ARC5] Crystal tester.

 There's many solid state tester designs around that let you check those xtals you run across at hamfests, etc., before you decide to buy. Make them with gator clips to accommodate the various pin types.

The military used this one (TS-39B/ TSM-1) and likely some other crystal testers

You can also simply plug a crystal into a grid dip meter in place of a coil and check the freq on a counter. 


A third method is shown in the third picture down, using a sig generator, scope and counter.

The military had a good crystal-test unit, but I cannot remember its nomenclature.
