:MEASure:TBASe:RFALl:BASE

Threshold Definition Commands

Command Syntax

:MEASure:TBASe:RFALl:BASE<amplitude>

<amplitude> is a double.

Query Syntax

:MEASure:TBASe:RFALl:BASE?

Description

Sets or queries the Rise/Fall threshold's global user-defined base-level setting. The top and base levels are used to locate a waveform's lower and upper percent threshold levels for rise time, fall time, and slew rate measurements. Specify the level in volts or Watts depending on the waveform type. Use :MEASure:TBASe:RFALl:TOP to set or query a custom top level.

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

The default setting is -240 mV. The maximum setting can be the highest vertical scale value, but is bounded by the top level (:MEASure:TBASe:RFALl:TOP). The minimum setting is bounded by the lowest vertical scale value.

Common Numerical Child Commands

This command supports the use of the following common numerical child commands: :DEFault, :MAXimum, :MINimum, and :STEP.
