• Global causes changes in this panel to be updated in all other measurements that also have Global selected in this panel.
When switching from Global to Local:
•
If a specific measurement has not been set to Local before then no changes are made to any of the values. You can update the
parameters.
• 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 effect this measurement. When switching from Local to Global, all fields will update to
the current Global parameters.
4. Tap Set Levels In and select either % or Absolute.
• % sets the High, Mid, and Low reference levels as percentages of the calculated Top and Base signal levels. Tap the Levels 10% -
90%, 20% - 80%, or Custom button to select the type of percent value to set.
• 10% - 90% sets the Low, Mid and High Ref values to 10%, 50% and 90% respectively for both rising and falling edges.
• 20% - 80% sets the Low, Mid and High Ref values to 20%, 50% and 80% respectively for both rising and falling edges.
• Custom opens the Rising and Falling Edge numeric entry fields to set High, Mid and Low Ref levels to different values for the
rising and falling edges of a waveform. Tap the Rising Edge and Falling Edge High, Mid, or Low fields and set the level using
the assigned multipurpose knob. Or double-tap the field and use the virtual keypad to enter a value.
• Absolute sets the High, Mid, and Low reference levels to specific signal levels. Tap the Levels Same or Unique buttons to select
the type of absolute value to set.
• Same sets the High, Mid, and Low reference for both rising and falling edges of a signal to the specified values. Tap the
Threshold High, Mid, or Low field and set the threshold using a multipurpose knob. Or double-tap the field and use the virtual
keypad to enter a value.
• Unique opens the Rising and Falling Edge numeric entry fields to set High, Mid and Low Ref levels to different values for the
rising and falling edges of a waveform. Tap the Rising Edge and Falling Edge High, Mid, or Low fields and set the level using
the assigned multipurpose knob. Or double-tap the field and use the virtual keypad to enter a value.
5. Tap the Base Top Method drop down tab and select the method from the list. This setting is only available when using the % level
setting.
6. Touch Hysteresis and use the assigned multipurpose knob to set the value.
7. Tap anywhere outside the Measurement configuration menu to close it.
Set measurement gates
Use this procedure to specify which portion of your waveform is used to take measurements.
Gating is set in the Gating panel of the Measurements configuration menu. See Measurement configuration menu overview on page 114.
To set measurement gates you must be taking a measurement. See Add a measurement on page 64.
Procedure
1. Double-tap a measurement badge to open the Measurement configuration menu.
2. Tap the Gating panel.
3. Tap Gating and select either Global or Local gating:
• Global causes changes in this panel to be updated in all other measurements that also have Global selected in this panel.
When switching from Global to Local:
• If a specific measurement has not been set to Local before then no changes are made to any of the values. You can update
the parameters.
