Step 1: Determine the
Standard
Characteristics

There are several situations that may require you to deline your own
calibration kit delinition. Here are three examples:
You are using a connector type (TNC or BNC for example) which is not one
l
of the selections under the CAL KIT menu.
You are using a built-in connector type, but your standards (such as a short)
l
have different characteristics than the built-in kit uses when performing a
calibration.
The following steps (explained later in detail) should be performed when
defining your own cal kit:
1. Determine the standard characteristics for the connector type you plan to
use.
2. Create a cal kit ASCII file or edit the one provided on the Example
Programs Disk.

3. Verify performance.
Determine the standard characteristics for the connector type you plan to use.
In particular, these are the characteristic impedance (Z,), the delay, and the
loss. These characteristics are common for the four supported types used by
the analyzer. Additionally, the capacitive model parameters, CO, Cl, C2, and
can be mathematically derived from the physical dimensions and material of
each calibration standard or from its actual measured response.
