Standard definition

Standard definition is the process of mathematical- ly modeling the electrical characteristics (delay, attenuation and impedance) of each calibration standard. These electrical characteristics can be mathematically derived from the physical dimen- sions and material of each calibration standards or from its actual measured response. A standard definition table (see Table 1) lists the parameters that are used by the 8510 to specify the mathemati- cal model.

Class assignment

Class assignment is the process of organizing cali- bration standards into a format which is compati- ble with the error models used in measurement calibration. A class or group of classes correspond to the seven calibration types used in the 8510. The 17 available classes are identified later in this note (see Assign classes).
