General Information
Achieving Specified Frequency Performance
Achieving Specified Frequency Performance
The standards in this calibration kit allow you to perform 1- or 2-port and TRM
(thru-reflect-match) calibrations.
NOTE
For best results, before beginning calibration refer to “Clarifying the Terminology
of a Connector Interface” on page 1-20 .
