[SI-LIST] Q on TDR coupon measurements

Hi all,
 

In researching the "state-of-the-art" for TDR measurement I ran across
an interesting measurement that I would welcome comments on from the
group.

After the coupon has been probed, the impedance is only measured over a
small portion (<25%) of the resultant waveform and then using
an "average mean* technique for reporting the impedance values.

 

In the opinion of the group - is this a valid technique? What are the
reasons for only using a small portion of the waveform ? Does anyone
know what an *average mean* value is??

 

Thanks in advance!!
