• If a specific measurement has been set to Local before, then changed back to Global and then again switched to Local, the
last used Local values are shown.
• Local causes changes in this panel to only ef
fect this measurement. When switching from Local to Global, all fields will update to
the current Global parameters.
4. Tap the Gating Type drop down tab and select the gating type from the list:
• None takes measurement across the entire waveform record.
• Screen takes measurements on that portion of the waveform shown in the display. When Zoom is on, the display is the zoom
window.
• Cursors takes measurements on that portion of the waveform between the cursors. Selecting Cursors opens cursors on the
measurement source. Set the cursors so that the waveform area of interest is between the cursors.
• Logic takes measurements only when the logical state of a specified waveform is true. If Logic gating is selected, continue with
the following steps.
• Search takes measurements between the start and stop times defined by a specified search.
• Time takes measurements between the times specified in the Start Gate Time and End Gate Time fields, relative to the trigger
point.
5. For the Logic and Search gates, tap the Source field and select the source from the list.
6. For the Logic gate, tap the Threshold field and use the assigned multipurpose knob to set the desired threshold dividing a logic Low
or High state.
7. For the Logic gate, tap the Hysteresis field and use the assigned multipurpose knob to set the desired hysteresis.
8. For the Logic gate, tap Active and select either the High or Low active state. High sets the gating to take measurements when the
specified waveform is an active High. Low sets the gating to take measurements when the specified waveform is an active Low logic
state.
9. Tap anywhere outside the Measurement configuration menu to close it.
10. Tap on a gating-enabled measurement badge to display the vertical gate bars on the waveform for that measurement.
11. To return measurement gating to its default value, open the Gating panel and select a gating type of None.
