Calibration for NA, CAT, and VVM Modes
Definitions
:
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.
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)
DUT: Not Applicable
S-parameters Corrected: S11 or S22
Standards: OPEN, SHORT, LOAD
Sweeps in ONE direction.
FULL 2-Port (Requires Option 122)
Most comprehensive calibration. Corrects all S-parameters
DUT: Non-Insertable or Insertable
Standards: OPEN, SHORT, LOAD on BOTH ports. Any THRU between ports.

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.
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.
