Calibration and Compensation Procedures Using Dedicated Test Fixture
6. Calibration and
Compensation
2. DUT connection terminal used as calibration reference plane
The following describes the calibration and compensation necessary for using the DUT
connection terminal of the dedicated test fixture as a calibration reference plane. As
indicated in
Table 6-4, only execution of open/short/load calibration is required.
1. How to check and change calibration kit definition
Check the definition of the working standard to be used and change it as required by
following the steps in
“How to Define Calibration Kit” on page 145.
2. How to select the measurement point table
To perform calibration data measurement for only one of the eight measurement point
tables, follow these steps to select the active table.
NOTE When performing calibration data measurement for all of the measurement point tables at
once, it is not necessary to select individual measurement point tables.
Step 1. Press the [Stml Select] key on the front panel to display the Stml Select softkey menu.
Step 2. Press the TABLE No. [ ] key in the softkey menu to display the TABLE No. [ ] softkey
menu.
Step 3. In the softkey menu, press the key (TABLE 1 to TABLE 8) corresponding to the
measurement point table for which calibration data measurement should be performed.
3. How to display the Calibration Dialog box
Follow these steps to display the calibration window.
Step 1. Press the [Cal/Compen] key on the front panel to display the Cal/Compen softkey menu.
Step 2. Press the CAL DIALOG key in the softkey menu to display the Calibration Dialog box
(
Figure 6-13).

(open/short/load)
*1. Perform DC open/short/load calibration as required.
*2. Use the Agilent 4287A option 004 (working standard set). Open calibration and short calibration can be made in
the open state or short state specified by the fixture; it is not necessary to use a special standard that has the same
shape as the DUT.
