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).
