3 VMA Mode
3.1 Digital Demod Measurement
to configure the trace data. For example, the following command sets the first
window data to Spectrum.
:DISP:DDEM:WIND1:DATA SPEC
Use the SCPI command:
:DISPlay:DDEMod:WINDow[1]|2|…|6:FORMat <enum>
to configure the trace display format. For example, the following command sets the
first window trace display format to Constellation.
:DISP:DDEM:WIND1:FORM CONS
Use the SCPI command:
:DISPlay:DDEMod:WINDow[1]|2|…|6:SEGMent <enum>
to configure the trace data of which segment to be displayed. For example, the
following command sets the segment1 trace data to be displayed.
:DISP:DDEM:WIND1:SEGM SEGM1
3.1.3.1 Data
Provides a menu of trace data choices for the selected window.
