Calibration for NA, CAT, and VVM Modes
Based on the SOLR/Unknown THRU calibration. For more information on
the Unknown THRU process, see the FieldFox Supplemental Online Help:
http://na.support.keysight.com/fieldfox/help/SupHelp/FieldFox.htm
Sweeps in BOTH directions.
FULL 2-Port (QSOLT) – Mechanical Cal ONLY (May require an option)
Quicker to perform QSOLT than Full 2-port. Corrects all S-parameters.
DUT: Insertable only
Standards: OPEN, SHORT, LOAD on port 1. Flush THRU between ports.
Recommended cal type for Insertable DUTs. A Cal Kit is NOT required for
port 2.
Sweeps in BOTH directions.
Enhanced Response Cal - Forward OR Reverse (May require an option)
Faster measurements than Full 2-Port.
DUT: Non-Insertable or Insertable. S-parameters PARTIALLY Corrected:
S21 and S11 (Forward) OR S12 and S22 (Reverse)
Standards: OPEN, SHORT, LOAD on ONE port. Defined or Flush THRU
between ports.
Sweeps in ONE direction.
TRL – Mechanical Cal ONLY
A complete 2-Port calibration with potentially better accuracy than Full
2-port. Corrects all S-parameters.
DUT: Non-Insertable or Insertable
Standards: Thru, Reflect, Line or variations of these. A TRL Cal Kit MUST be
selected to see this Cal Type
Sweeps in BOTH directions.

1-port Response Cals (Open or Short)
Calibrate the magnitude and phase of a measurement using ‘modeled’
mechanical standards. Measurement accuracy is better than Simple
Response Cals (available on the main Cal page - see “Calibration Type” on
page 134) but NOT as good as full 1-port cal. Corrects either S11 or S22.
Can be used with Isolation (see following section). Learn more in “Simple
Response Cals ” on page 132
Also select an Enhanced Response Optimization. Learn more in “Enhanced
Response Optimization” on page 139.
