waveforms
Overlay
The Waveform Menu
Channel Mode Field
The Overlay mode inserts all bits of a label in a single waveform to form a
composite waveform label. The onscreen indication for the Overlay mode is
"All" following the label name.
Viewing State Data in Overlay Mode
When all assigned waveforms in a label are Overlaid, the value of the data is
displayed to the right of each new transition in the waveform display.
If
the sec/Div is set to view a large increment of time, or the waveform scaling
is set to Small or medium, the state data readout
will
not fit between
transitions. To display the state data readouts
within
the waveform, expand
the sec/Div and use the large waveform setting.
If
symbols are assigned to
represent data values, the symbol is displayed.
