Delta Time Commands

Command Syntax

:MEASure:HORizontal:DTIMe:REGion {DISPlay | WAVeform | REGion{1:8}}

Query Syntax

:MEASure:HORizontal:DTIMe:REGion?

Description

Select a time span over which the :MEASure:HORizontal:DTIMe measurement is made.

DISPlay
The measurement is performed on on-screen data only.
WAVeform
The measurement is performed on all waveform data, whether the data is displayed on-screen or not.
REGion{1:8}
The measurement is performed across one of eight regions. Regions are defined using the :REGions:REGion{N}:STATe command.

This setting can affect analysis as waveforms are moved horizontally. For example, a Rise Time measurement is made on the first edge. When DISPlay is selected and a waveform is moved horizontally, as different edges become the first on the screen, the measurement moves to those different edges. When WAVeform is selected, the measurement remains on the first edge in the data even when that edge is moved horizontally off the screen.

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.
