MDATa Unformatted trace data (see SDATa) after evaluation of trace mathematics.
[Data access point 5]
NCData Factory calibrated trace data: the values are obtained right after applying the fac-
tory calibration but before applying a user-defined calibration (if any).
[Data access point 1]
UCData Uncalibrated trace data.
[Data access point 0]
Note:
●
the respective trace must represent a wave quantity or ratio
●
driving and receiving port must not be on a switch matrix
Otherwise an error occurs.
The following parameters denote the error terms generated during a calibration.
Table 8-3: Error terms in the CALCulate:DATA... commands
Error Term Description Receive Ports (S-parameter)
SCORr1, ..., SCORr12 2-port error terms; see [SENSe<Ch>:
]CORRection:DATA.
1 and 2 (S11, S12, S21, S22)
SCORr13 Directivity 3 (S33)
SCORr14 Source match 3 (S33)
SCORr15 Reflection tracking 3 (S33)
SCORr16 Isolation 3 (S31)
SCORr17 Load match 3 (S31)
SCORr18 Transmission tracking 3 (S13)
SCORr19 Isolation 1 (S13)
SCORr20 Load match 1 (S13)
SCORr21 Transmission tracking 1 (S13)
SCORr22 Isolation 3 (S32)
SCORr23 Load match 3 (S32)
SCORr24 Transmission tracking 3 (S32)
SCORr25 Isolation 2 (S23)
SCORr26 Load match 2 (S23)
SCORr27 Transmission tracking 2 (S23)
Note: The error terms are channel-specific; they apply to the active calibration of chan-
nel no. <Chn> or to the factory calibration (if no channel calibration is active). For the
factory calibration, the query form is allowed only (no change of factory calibration
data).
Tip: Use the generalized command [SENSe<Ch>:]CORRection:CDATa to read or
write error terms for arbitrary analyzer ports. For additional programming examples
refer to Chapter 9.2.5.3, "Saving and Recalling Error Terms", on page 1407.
