Default Re: Measuring Resonant Frequency

Very interesting discussion.

I recall that back in the 60`s and 70`s there were SigGen G.D.O. adapters
- also some DIY, very simple ones - that provided accurate resonant freq.
measurements and GDO like features.

"GDO-like" adapter Pros: Accurate (SigGen accuracy), stable and constant
calibrated output level. Deep indicator was a Hi Z analog V-Meter.

Con: need to be hub-connected by coax to the SigGen.
