:REGions:REGion{N}:SOURce

Command Syntax

:REGions:REGion{1:8}:SOURce {CHANnel{N} | DIFF{1:8}{A|C} | FUNCtion{1:64} | WMEMory{1:8}}

{N} identifies a specific channel in the form "<connection1-8>_<ch1-8>". With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1-8>". For example, connection 4 channel 2 is CHANnel4_2.

:REGions:REGion{1:8}:SOURce?

Description

This command specifies the waveform source the region applies to.

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
