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 ZNB/ZNBT also supports a SMARTerCal based on the calibration units. The
calibration units provide the n-port system error correction data (TOSM or UOSM); a
subsequent power calibration sweep completes the calibration.
4.5.7.2 Calibration types
The names of the SMARTerCal calibration types consist of a prefix "P" (indicating the
additional power calibration) plus the system error correction type. The R&S ZNB/
ZNBT supports the SMARTerCal equivalent of all full n-port system error corrections;
an overview is shown below.

The selection criteria for the SMARTerCal calibration types are identical to the criteria
for system error corrections. For an overview, refer to
