Hi Everyone,

I have been writing again. Including this month, the last four Technical 
Tidbits in http://emcesd.com have been on unusual uses for a comb 
generator. This month the Technical Tidbit is:

Using a Comb Generator with a Pair of Current Probes to Measure Cable 
Resonance
(A Useful Technique When a Tracking Generator is not Available)

This month's Technical Tidbit describes a simple technique using a comb 
generator and a pair of current probes to measure the resonant 
frequencies of a cable.

Abstract: A comb generator RF source can be a handy substitute when a 
tracking generator is not available on a spectrum analyzer. In this 
case, a USB powered comb generator RF source is used to supply the 
signal used to measure the resonant frequencies of a cable.

The link to the article is the picture of the experimental setup at 
http://emcesd.com. The direct link is:

Separately, I have come up with a new way to express the age of a human 
being. Using this method I have just turned 20! Being an engineer, I 
like to express things in terms of Pi. So divide your age by Pi and you 
have your new age! I am 20Pi. Sounds better than my actual age!

Doug
