## Command Syntax

    :MEASure:TBASe:GENeral:BASE<amplitude>

<amplitude> is a double.

## Query Syntax

    :MEASure:TBASe:GENeral:BASE?

## Description

Sets or queries the General threshold's global user-defined base-level setting. The top and base levels are used to locate a waveform's lower, middle, and upper percent threshold levels for measurements. Specify the level in volts or Watts depending on the waveform type. Use `:MEASure:TBASe:GENeral:TOP` to set or query a custom top level.

Before this custom base level can be applied to measurements, use the `:MEASure:TBASe:GENeral: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:GENeral: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`.
