Basic Calibration
Before executing calibration, you need to select a calibration kit. If you use a
calibration kit other than a predefined one, you need to define it. If the connector type
of the standard of the calibration kit you use has polarity (the distinction between
male and female), you need to change the standard class definition of the calibration
kit depending on the standard you actually use. For more information, see Modifying
Calibration Kit Definition.
If you select a predefined calibration kit, (m) and (f) in the name (label) of the
standard displayed in the soft key indicate male (m) and female (f) for the analyzer's
connector, respectively.
Click Select Port.
For 1-port;
In 1-port calibration, calibration data are measured by connecting an OPEN
standard, a SHORT standard, and a LOAD standard to the desired test port. This
calibration effectively eliminates the frequency response
reflection tracking error,
directivity error, and source match error from the
test setup in a reflection test
using that port.
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.
6. Select a test port (and corresponding S parameter) on which 1-port calibration will
be performed.
7.
Connect an OPEN calibration standard to the selected test port
(connector to which
the DUT is to be connected).
8. Click Open to start the calibration measurement.
9. Connect a SHORT calibration standard to the selected test port (connector to which
the DUT is to be connected).
10. Click Short to start the calibration measurement.
11. Connect a LOAD calibration standard to the selected test port (connector to which
the DUT is to be connected).
12. Click Load to start the calibration measurement.
13. Click Done to terminate the 1-port calibration process. Upon pressing this key,
calibration coefficients will be calculated and saved. The error correction function
will also be automatically enabled.
For 2-port;
In full 2-port calibration, calibration data are measured by connecting an OPEN
standard, a SHORT standard, or a LOAD standard to two desired test ports (or
a THRU standard between two ports).This calibration effectively eliminates the
directivity error, crosstalk, source match error, frequency response reflection
tracking error, and frequency response transmission tracking error from the test
setup in a transmission or reflection test using those ports. This calibration
