## Query Response

    {1 | 0}

## Description

This command enables or disables the region's Global Region setting that specifies whether the region applies to all waveforms. This setting can be applied to each of the eight regions.

Regions let you restrict the data used for a measurement to a specific area of the source waveform as defined by left and right X-axis limits.

Use the `:REGions:REGion{N}:X{1:2}` command to set the x-axis boundaries for each region.

After defining one or more regions, use the `:REGion` child command of a specific measurement to apply a region to the measurement. For example, limit a rise-time measurement to the data within region 3, use the following command:

    :MEASure:HORizontal:RTIMe:REGion REGion3

If you want to make a two-source measurement (like Δt, Phase, or Crossing) within a region, global regions (which are defined for all signal sources) are required.

The Jitterp-p and Jitterrms measurements cannot be made on a region.
