Modifying Trl Standards - Agilent Technologies 8719D User Manual

9. Repeat the value modification for the characteristics listed below:
Saving the modified calibration constants
If you made modifications to any of the standard definitions, follow the remaining steps in this
procedure to assign a kit label, and store them inthe non-volatile memory. The new set of
standard definitions will be available under ,U$%@ XKX? until you save another user kit.
You may also save the user kit to disk, by selecting the particular kit at the
time you save a measurement result.
In order to use the TRL technique, the calibration standards characteristics must be entered
into the analyzer's user defined calibration kit.
This example procedure shows you how to define a calibration kit to utilize a set of TRL
(THRU, REFLECT, LINE) standards This example TRL kit contains the following:
"flush" short for the REFLECT standard (0 second offset)
n
50 ohm transmission line with 80 ps of offset delay for the LINE
n
Hewlett-Packard strongly recommends that you read product note 8510-8A
before you attempt to modify the standard definitions 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 8719D/20D/22D.
For a discussion on TRL calibration, refer to "TRL/LRM Calibration" in
Chapter 6, "Application and Operation Concepts."
