Test Head Coaxial Terminal Used As Calibration Reference Plane - Agilent Technologies Twelfth 4287A RF LCR Operation Manual

1. Test head coaxial terminal used as calibration reference plane

The following describes the calibration and compensation procedure with a dedicated test
fixture when the test head coaxial terminal is used as a calibration reference plane. In this
case, the coaxial terminal serving as a calibration reference plane is generally a 7-mm
terminal connected by a 3.5-mm-to-7-mm adapter. The calibration and compensation
shown in Table 6-3 are carried out in the specified sequence.

*1. Also performs DC open/short/load calibration if required.
*2. This calibration is performed only when high-accuracy high-Q measurement (low dissipation factor measure-
ment) is required at about 1 GHz or more.
*3. When you use a dedicated test fixture with registered electrical length, automatic entry is made by simply select-
ing the model number in the softkey menu.
*4. Also performs DC open/short compensation if required.
1. How to define calibration and compensation kit and how to register electrical
length for port extension compensation
Step 1. Check the definition of the calibration kit to be used according to "How to Define
Calibration Kit" on page 145 and change it if required.
Step 2. Check the definition of the compensation kit to be used according to "How to Define
Compensation Kit" on page 147 and change it if required.
Step 3. When using test fixtures other than 16191A, 16192A, 16193A, 16194A, 16196A, 16196B,
or 16196C, register the name and electrical length of the test fixture as described in
"Registering the Electrical Length of Unregistered Test Fixtures" on page 149.
2. How to select the measurement point table
To perform calibration or compensation data measurement for only one of the eight
measurement point tables, perform the following steps to select the table as the active table.
NOTE When performing calibration or compensation data measurement for all of the
measurement point tables, is not necessary to select the measurement point table.
Step 1. Press the
