Changing the Calibration Kit Definition

In most measurements, the user can use pre-defined calibration kits as they are. However, it
may be necessary to change the definition of a calibration kit (or create a new one) when
changing the pre-defined connector between male and female (e.g. from OPEN (f) to
*1
OPEN (m)
) or when a special standard is used or a high degree of accuracy is demanded.
When it is necessary to change the definition of a calibration kit that contains a calibration
device but no calibration kit model, the user must fully understand error correction and the
system error model.
A user-defined calibration kit may be used in the following circumstances.
When the user wants to use connectors other than those pre-defined in the calibration
kits for the E5070B/E5071B (e.g., a SMA connector).
When the user wants to use different standards in place of one or more standards
pre-defined in the E5070B/E5071B. For example, when three offset SHORT standards
are used instead of OPEN, SHORT, and LOAD standards.
When the user wants to modify the standard model of a pre-defined calibration kit and
turn it into a more accurate model. It is possible to perform better calibration if the
performance of the actual standard is better reflected in the standard model. For
example, you may need to define the 7-mm LOAD standard as 50.4 Ω instead of 50.0
Ω.
*1.The designations (m) and (f) in the name (label) of the standard indicate male (m) and female
(f) analyzer connectors.
