Description

For the indicated waveform memory, sets the custom top-level setting. The top and base levels are used to locate a waveform's lower, middle, and upper threshold levels during the following measurements: duty-cycle distortion, rise time and fall time. Specify the level in volts or Watts depending on the waveform type. Use :WMEMory{1:8}:UDEFined:BASe to set or query a custom base level.

Before this custom top level can be applied to measurements, use the :MEASure:TBASe:METHod command to select custom top-base definitions.
