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.
Flush THRU - When the test port cables mate together when measuring an
Insertable DUT. The THRU standard has no loss and no electrical 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.
FULL 2-Port (Available with Option 122).
FULL 2-Port (QSOLT) – Mechanical Cal ONLY (Available with Option 122)
Enhanced Response Cal (Forward OR Reverse with Option 122)
58
Most comprehensive calibration. Corrects all S-parameters.
DUT: Non-Insertable or Insertable
Standards: OPEN, SHORT, LOAD on BOTH ports. Any THRU between ports.
Sweeps in BOTH directions.
Quicker to perform than Full 2-port. Corrects all S-parameters.
DUT: Insertable only
Standards: OPEN, SHORT, LOAD on port 1. Flush THRU between ports.
Sweeps in BOTH directions.
Faster measurements than Full 2-Port.
DUT: Insertable only
S-parameters Corrected: S21 and S11 (Forward) OR S12 and S22 (Reverse)
Standards: OPEN, SHORT, LOAD on ONE port. Flush THRU between ports.
Sweeps in ONE direction.
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.
