Modifying Calibration Kit Standards
Note
Numerical data for most Hewlett-P ackard calibration kits is provided in the
calibration kit manuals .
The following section provides a summary of the information in the 8510-5A application note ,
as well as HP 8753D menu-specic information. F or a detailed description of the menus and
softkeys located in this section, as well as information about when user-dened calibration kits
should be used, refer to Chapter 6, \Application and Operation Concepts ."
Denitions
The following are denitions of terms:
A \standard" (represented by a number 1-8) is a specic , well-dened, physical device used
to determine systematic errors . F or example , standard 1 is a short in the 3.5 mm calibration
kit.
A standard \type" is one of ve basic types that dene the form or structure of the model to
be used with that standard (short, open, load, delay/thru, and arbitrary impedance); standard
1 is of the type short in the 3.5 mm calibration kit.
Standard \coecients" are numerical characteristics of the standards used in the model
selected. F or example , the oset delay of the short is 32 ps in the 3.5 mm calibration kit.
A standard \class" is a grouping of one or more standards that determines which of the eight
standards are used at each step of the calibration. F or example , standard number 2 makes up
the S
11
A reection class .
Outline of Standard Modication
The following steps are used to modify or dene user kit standard models , contained in the
analyzer memory . It is not possible to alter the built-in calibration kits; all modications will be
saved in the user kit.
1. T o modify a cal kit, rst select the predened kit to be modied. This is not necessary for
dening a new cal kit.
2. Dene the standards . F or each standard, dene which \type" of standard it is and its
electrical characteristics .
3. Specify the class where the standard is to be assigned.
4. Store the modied cal kit.
