SCPI Command

CALCulate<Ch>[:SELected]:DATA:FDATa?

Description

Reads out the formatted data array.

The formatted data array is the data, whose processing is completed including the formatting as the last step. Such data represent the data trace values as they are shown on the screen.

The array size is 2N, where N is the number of measurement points.

For the n–th point, where n from 1 to N:

<numeric 2n–1> Value 1 depends on the trace format (see table below);

<numeric 2n> Value 2 depends on the trace format (see table below).Reads out or writes the formatted data array.
