The following parameters are related to trace data (see also diagram in Chapter 4.1.6,
"Data flow", on page 93):
Table 7-2: Data format identifiers used in the CALCulate:DATA... commands
FDATa Formatted trace data, according to the selected trace format
(CALCulate<Chn>:FORMat). One value per trace point for Cartesian diagrams,
two values for polar diagrams.
[Data access point 6]
SDATa Unformatted trace data: real and imaginary part of each measurement point. Two
values per trace point irrespective of the selected trace format. The trace mathe-
matics is not taken into account.
[Data access point 4]
MDATa Unformatted trace data (see SDATa) after evaluation of trace mathematics.
[Data access point 5]
TSData Raw measured values in pulse profile mode, only available for wave quantities
and if pulse profile mode is active. The values correspond to the real output val-
ues of the A/D converter; acquired at a fixed sampling rate. The number of val-
ues in the returned array is not correlated with the number of sweep points.
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
Otherwise an error occurs.
The following parameters denote the error terms generated during a calibration.
