Modifying TRM Standards

In order to use the TRL technique, the calibration standards characteristics must be entered into the analyzer’s user deflned calibration kit.

This example procedure shows you how to dehne a calibration kit to utilize a set of TRM (THRU, REFLECT, MATCH) standards. This example TRM kit contains the foliowing:

nzero length THRU

n“flush” short for the REFLECT standard (0 second offset)

n50 ohm termination for the MATCH (inhnlte length line)

Note Hewlett-Packard strongly recommends that you read product note 8510-8A before you attempt to modify the standard de5nitions The part number of this product note is 5091-3645E. Although the product note was written for the HP 8510 family of network analyzers, it also applies to the HP 8753E.

For a discussion on TRL calibration, refer to “TRL/LRM Calibration” in

Chapter 6, “Application and Operation Concepts. n
