Description

For the indicated function, selects the method used to define the waveform top and base definitions. The command is equivalent to setting the signal's Top-Base Definition in the Thresholds > Rise/Fall tab of the Configure Measurements dialog box.

AUTO
Specifies that the top (100%) and base (0%) levels be automatically determined using a histogram of the signal's amplitude values. This is the default setting.
