APPENDIX B
Open and short compensation
The open/short compensation used in Agilent’s instrument models the residuals as a linear network
represented by the ABCD parameters, much like the open/short/load compensation techniques
described previously in this document. The difference is that the open/short compensation assumes
the unknown network as a “symmetrical network”. From this restriction, the open/short compensa-
tion does not require the load measurement to know each value of ABCD parameters. A theoretical
explanation and procedure are given in Figure B-1.
