makes it possible to perform measurements with the highest possible accuracy.
A total of twelve error terms, six each in the forward direction and the reverse
direction, are used in a calibration.
1. Press Cal key.
2. Click Cal Kit, then select the calibration kit.
3. If the name (label) of the calibration kit has been changed, the label is displayed as
the soft key.
4. An asterisk (*) on the upper right of the softkey corresponding to a predefined
calibration kit indicates that its definition value has been changed from the factory
setting by the user.
5. Click Calibrate > 2-Port Cal.
6. Click Select Ports, then select the test ports on which you will perform full 2-port
calibration. (In the procedure below, the selected test ports are denoted as x and y.)
7. Click Reflection.
8. Connect an OPEN calibration standard to test port x (the connector to which the
DUT is to be connected).
9. Click Port x Open to start the calibration measurement (x denotes the test port to
which the standard is connected).

If you select the calibration kit which has different calibration definitions for
each gender, (m) and (f) in the name (label) of the standard displayed in
the softkey indicate male (m) and female (f) for the analyzer's connector,
respectively.
10. Disconnect the OPEN calibration standard and replace it with a SHORT calibration
standard.
11. Click Port x Short to start the calibration measurement (x denotes the test port to
which the standard is connected).
12. Disconnect the SHORT calibration standard and replace it with a LOAD standard.
13. Click Port x Load to start the calibration measurement (x denotes the test port to
which the standard is connected).
14. Repeat the above procedure for port y.
15. Click Return.
16. Click Transmission.
17. Make a THRU connection between ports x and y (between the connectors to
which the DUT is to be connected).
18. Click Port x-y Thru to start the calibration measurement (x and y denote the test
ports between which the THRU connection is being made).
19. Click Return.
20. If an isolation calibration must be performed using a LOAD standard, follow the
procedure below.
21. Click Isolation (Optional).
22. Connect a LOAD standard to each of the two test ports (connectors to which the DUT
is to be connected).
23. Click Port x-y Isol to start the calibration measurement (x and y denote the port
numbers to which the LOAD standard is connected).
24. Click Return.
25. Click Done to terminate the full 2-port calibration process. Upon pressing this key,
calibration coefficients will be calculated and saved. The error correction function
will also be automatically enabled.
