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> real number in rectangular format, real part in
polar and Smith chart formats;
<numeric 2n> 0 in rectangular format, imaginary part in polar
and Smith chart formats.
(Command/Query)
CALCulate<Ch>[:SELected]:DATA:FDATa - the active trace of channel,
CALCulate<Ch>:TRACe<Tr>:DATA:FDATa - the trace <Tr> of channel,
<Ch>={[1]|2|...16}
<Tr>={[1]|2|...16}
When data is being written it is recommended to hold the sweep before
and update the screen after write.
