Modify the Cal Kit
With this method it is only necessary to use adapter B. The calibration kit thru definition is
modified to compensate for the adapter and then saved as a user kit. However, the electrical
delay of the adapter must
be found.
1. Perform a l-port calibration on PORT 2.
2. Connect adapter B to the test port.
3. Add a short to the open end of the B adapter.
Measure the delay of the adapter by pressing
5. Divide the resulting delay measurement by 2.
6. Determine the offset delay of the calibration short by the standard menu
(see Standard Menus”).
7. Subtract the short offset delay from the value calculated in step 5. This corresponds to the
delay of adapter B.
8. Modify the calibration kit thru by entering in the electrical delay of adapter B.
Save this as a user kit.
9. Perform the desired calibration with this new user kit.
10. Measure the test device.
