[:SENSe]:SPECtrum:DETector[:FUNCtion](?)
Selects or queries the display detector (method to be used for decimating traces
to fit the available horizontal space on screen).
The number of horizontal pixel positions on screen is generally smaller than that
of waveform data points. When actually displayed, the waveform data is
therefore thinned out according to the number of horizontal pixel positions which
can be displayed. For details, refer to the WCA230A User Manual .
