Calibration Type - Keysight N9923A FieldFox User Manual

The bottom box shows the S-parameters that are displayed but NOT corrected by
the current performed calibration, but rather the CalReady calibration. Learn more
about CalReady on page 63.

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 – When the test port cables mate together when measuring an
Insertable DUT. Flush THRU is also a Defined THRU with a definition of zero loss and
zero length.
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.
1-Port (OSL)
FULL 2-Port (Requires Option 122).
Calibration for NA, CAT, and VVM Modes
DUT: Not Applicable
S-parameters Corrected: S11 or S22
Standards: OPEN, SHORT, LOAD
Sweeps in ONE direction.
Most comprehensive calibration. Corrects all S-parameters.
DUT: Non-Insertable or Insertable
Standards: OPEN, SHORT, LOAD on BOTH ports. Any THRU between ports.

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.
