Calibration Type / Source

Selects the calibration type for the selected physical ports. For an overview, refer to

Table 9-7.

The reflection calibration types can be used for any combination of physical ports:

reflection calibrations are performed for each selected port.

A transmission calibration type requires at least two physical ports. For the unidirec-

tional transmission calibration types ("Trans Norm", "One Path Two Ports"), the direc-

tion ("Source" port) must be specified in addition.

Transmission normalization and "One Path Two Ports" calibration types require two-

port (Through) characterization data for the cal unit. For current calibration units, how-

ever, these two-port characterizations are typically not part of the factory characteriza-

tion. If a tooltip indicates missing two-port characterization data, simply perform a new

characterization of your cal unit. In the first dialog of the "Characterization" wizard,

select "Take All OSM and Through" to make sure that the necessary two-port data is

acquired. See also "Characterization wizard" on page 506.

Remote command:

[SENSe<Ch>:]CORRection:COLLect:AUTO:TYPE

[SENSe<Ch>:]CORRection:COLLect:AUTO:PORTs:TYPE

Proceeds to Step 2: Connections. "Next" is unavailable (and a warning is displayed) if

the following happens:

●

The selected characterization data do not cover all the ports to be calibrated.

●

The selected characterization data do not contain all standards needed for the

selected calibration type.

Step 2: Connections

Defines the port assignments between the R&S ZNL/ZNLE and the calibration unit.
