Access: "Protocol" menu > "Parallel buses" > "Display" tab
The Display tab provides settings for clocked buses and analog bus display.
Show decode table
The setting is relevant only for clocked buses to check the data words. If enabled, a results
box opens with decoded values of the bus signal and its time. Each clock edge corre-
sponds to one row in the table. Below the table, you can select the data format for the
bus values
Upper / Lower reference voltage
Set the upper and lower level for the quasi-analog waveform of the bus signal. The highest
bus value corresponds to the upper voltage level, and the lowest bus value to the lower
voltage level.
