Description
For the indicated T-domain parameter or S-parameter trace, sets or queries the custom top-level setting. The top and base levels are used to locate a waveform's lower, middle, and upper threshold levels during measurements. Specify the level in the units shown in the following table, depending on the waveform type. Use :TRACe:UDEFined:BASe to set or query a custom top level. Before this custom base level can be applied to measurements, use the :MEASure:TBASe:METHod command to select custom top-base definitions. This setting can be set from the front panel by clicking Measure > Configure Base Measurements and selecting in the Top-Base Definition tab in the Configure Measurements dialog.
