Re: Unknown Thru Calibration Algorithm #calibration


 

It's not mine but I do share the sentiment ;)

Hi all,

I am currently working on implementing various VNA calibration
algorithms
in MATLAB. I have succesfully implemented SOLT and one-port algorithms,
but
I am having trouble getting my head around the unknown thru/8 term
2-port
calibration model. I've been basing my work off the following document
by
Doug Rytting

, which has been very useful. I'm currently trying to use page 23+24 of
this document to build my unknown thru calibration algorithm, but I'm
uncertain how I can produce the error terms needed for the constant k.

I would greatly appreciate any help, or links that may prove useful.
