Define standards

A glossary of standard definition parameters used with the Agilent 8510 is included in this section. Each parameter is described and appropriate con- versions are listed for implementation with the 8510. To illustrate, a calibration kit for WR-62 rec- tangular waveguide (operating frequency range

12.4to 18 GHz) will be defined as shown in Table 1. Subsequent sections will continue to develop this waveguide example.

Model for reflection standard (short, open, load or arbitrary impedance)

Model for transmission standard (Thru)

Figure 2. Standard definition models

The mathematical models are developed for each standard in accordance with the standard defini- tion parameters provided by the 8510. These stan- dard definition parameters are shown in Figure 2.
