Calibration Type - Keysight B Series User Manual

Calibration for NA, CAT, and VVM Modes
The top box shows the properties of the current calibration that you performed
and the displayed S-parameters that it is correcting.
The bottom box shows the S-parameters that are displayed but NOT corrected
by the current performed calibration, but rather the CalReady calibration.

Calibration Type

The FieldFox simplifies the calibration process by recommending the most
accurate and efficient calibration type based on the displayed S-parameters.
However, there may be times when you may want a little more accuracy or a
little faster sweep time. The following information can help you learn about the
various calibration choices.
Definitions:
Non-insertable DUT – A device whose
connectors could NOT mate together. They
either do not have the same type of connector
or they have the same gender. This also means
that the test port cables could NOT mate
together as in the above diagram.
Defined THRU – A THRU standard for which there is a Cal Kit definition such as
in the 8551xA Cal Kits.
Flush THRU (also known as Zero length THRU) – When the test port cables
mate together when measuring an Insertable DUT. No actual THRU standard is
required because the test port cables are directly connected. Flush THRU is
also a Defined THRU with a definition of zero loss and zero length.
Unknown THRU - Any THRU connection between the test ports. For more
information see the FieldFox Supplemental Online Help:

Sweep Directions – Both FULL 2-Port Cals listed below result in correction
that requires background measurements sweeps in both directions, regardless
of the displayed measurements. The displayed traces are updated at a slower
rate than Enhanced Response and 1-port calibrations, which require sweeps in
one direction only.

Insertable DUT – A device whose connectors
could mate together. They have the same type
of connector and opposite or no gender. This
also means that the test port cables could
mate together, as in the above diagram.
