6-6. Class Assignments
Calibration Kit
Disk File Name:
The number of standard classes required depends on the type of calibration being performed,
and is identical to the number of error terms corrected. A response calibration requires only
one class, and the standards for that class may include an open, or short, or thru. A l-port
calibration requires three classes. A full calibration requires 10 classes, not including two
for isolation.
The number of standards that can be assigned to a given class may vary from none (class not
used) to one (simplest class) to seven. When a certain class of standards is required during
calibration, the analyzer will display the labels for all the standards in that class (except when
the class consists of a single standard). This does not, however, mean that all standards in a
class must be measured during calibration. Unless band-limited standards are used, only a
single standard per class is required.
Note
It is often to keep the number of standards per class to the bare
needed (often one) to avoid confusion during calibration.
