Calibration and Compensation
Calibration and Compensation Procedures Using Dedicated Test Fixture
6. Calibration and
Compensation
• To erase all compensation data after measurement is finished, press the Clear
Compensation Data
button.
• To close the dialog box during compensation, press the Close button.
15. How to select the table range for executing the compensation
Select the table range for executing the compensation by making the appropriate setting in
the
Select Compensation Table area of the Compensation Dialog box window.
If you select Active table only, compensation will only be executed for the measurement
point table (active table) selected in
“2. How to select the measurement point table” on
page 121.
If you select Calibrate all tables, compensation will be executed for all measurement point
tables.
NOTE If you select Calibrate all tables (to execute compensation for all measurement point
tables) in the Compensation Dialog box, calibration data measurement will be performed
in accordance with the conditions set in
“4. How to select the table range for executing the
calibration” on page 123.
16. How to confirm port extension compensation (fixture selection)
Check that the test fixture selected in “13. How to carry out port extension compensation
(fixture selection)” on page 127 is indicated in the Fixture Type box of the Compensation
Dialog box.
NOTE Instead of using the procedure of “13. How to carry out port extension compensation
(fixture selection)” on page 127, it is also possible to perform (or change) the setting of the
port extension compensation (fixture selection) in this Compensation Dialog box.
To perform (or change) the port extension compensation (fixture selection) setting, move
the cursor to the
Fixture Type box and select the model number (or a fixture name
registered by the user) of the test fixture to be used. When using the mouse, click the
down-arrow  to the right of the
Fixture Type box to open a drop-down list box. Select the
model number (or a fixture name registered by the user) of the test fixture to be used from
the list by clicking the desired option.
Be sure to set the port extension compensation (fixture selection) before executing
measurement of open/short compensation data. If the fixture selection is changed after
measurement of open/short compensation data, the open/short compensation data are
automatically erased.
17. How to measure open compensation data
Follow these steps to measure the open compensation data.
Step 1. Set the DUT connection terminal of the dedicated test fixture to the open state. For how to
set it to the open state, see the Operation Manual of the test fixture to be used.
Step 2. Click the OPEN button in the compensation window and measure the open compensation
data.
