4.5.7.1 Calibration procedure
A SMARTerCal is a fully menu-guided process which is performed like a regular sys-
tem error correction. The calibration wizard defines the calibrated ports and the calibra-
tion type; it also initiates the calibration sweeps for all calibration standards. The cali-
bration sweep for the external power meter is performed in analogy to a sweep for a
one-port calibration standard. However, the analyzer uses the "Reference Receiver Cal
Power" setting from the scalar power calibration. The order of the system error correc-
tion and power calibration sweeps is arbitrary; ensure that you always connect the
proper equipment.
The R&S ZNA also supports a SMARTerCal based on the calibration units. The cali-
bration units provide the n-port system error correction data (TOSM or UOSM); a sub-
sequent power calibration sweep completes the calibration.
4.5.7.2 Calibration types
Except for "Adapter Removal", the names of the SMARTerCal calibration types consist
of a prefix "P" (indicating the additional power calibration) plus the system error correc-
tion type. The R&S ZNA supports the SMARTerCal equivalent of all full n-port system
error corrections; an overview is shown below.
