#188591 - measuring reactive component values
Responding to: Joseph Hebert's previous message
Hi Again,

I ask this because I was recently organizing my office, moving old files out to my annex, when I ran across an old lab report from undergraduate school. It involved using an oscilloscope to measure the capacitance of an unknown capacitor.

Frankly, I've always considered capacitor values in particular suspect at best, but fortuitiously uncritical. I have an LCR meter that gives me a nominal value, but even then it tells me nothing about how the component behaves as a function of frequency.

Still, I wonder how much value it would be to characterize a component independently of the circuit it's going in. Any thoughts?
