Gating panel (Measurement configuration menu)
Use Gating to confine a measurement to a certain part of a waveform.
T
o open the Gating panel:
1. Double-tap a Measurement badge in the Results bar to open the Measurement configuration menu.
2. Tap the Gating panel.
Gating panel, fields and controls
Not all items listed in the table are shown for all measurements; The panel shows fields and controls relevant to the selected
measurement.
Field or control Description
Gating Sets whether this measurement's gating settings are Global or Local.
When Global is selected, changing anything in this panel causes the same change to all other
measurements that also have Global selected.
When Local is selected, settings in this panel only ef
fect this measurement.
Gating Type Sets the gate type used to take measurements.
None: Measurements are taken across the entire record.
Screen: Measurements are taken on the portion of the waveform shown on the display. When zoom is
on, the ‘display’ on which to measure is the zoom window.
Cursors: Measurements are taken on the portion of the waveform between the cursors.
Logic: Measurements are taken only when the logical state of a specified waveform is true.
Search: Measurements are taken between the start and stop times defined by a specified search.
Time: Measurements are taken between the times specified in the Start Gate Time and End Gate
Time fields, relative to the trigger point (0 s).
Source Sets the signal source to use for Logic or Search gates.
If Gating Type is Logic, the Source field lists all available sources.
If Gating Type is Search, the Source field lists all available searches.
Threshold Sets the threshold value for the Logic gate source to be considered a logic 1 value. Available when
Source is Logic.
Hysteresis Sets the Hysteresis value for the Logic gate source. Available when Source is Logic.
Active Sets the logic state value for the Logic gate source. Available when Source is Logic.
Start Gate Time
End Gate Time
Sets the starting time (Start Gate) and ending time (End Gate) between which to take a measurement.
The starting and ending gate times are relative to the trigger time (0 s). Available when Gating Type is
Time.
Guidelines
•
Only one gated region is allowed per measurement. You can create duplicate measurements and define different gates for each one.
• Tap on a gating-enabled measurement badge to display the vertical gate bars on the waveform for that measurement.
• Gating is indicated by two vertical bars; one at the start of the gated region and one at the end.
• If the measurement has more than one source, gate bars are drawn on both sources.
