Do I know the process? Well, does making over 14,000 models from
measurement qualify us as knowing how to do it?
I'm not familiar with the 4155 but it looks like it would be OK for
measuring DC characteristic and getting C_comp. But where are the AC
measurements? Word Generator? Power for the device under test?

Dear Tom,
You got my idea...
Do you know the process of creating a ibis model from measurement?
We are thinking of buying agilent's HP-4155 for model creation...
Thanks.
