Turn On Markers

1. From the menu bar, choose Measure > Measure Setup.

2. Select a Measure Mode: Std Vertical, Std Horizontal, or My Measure.

3. Touch the Show All button to display Help Markers for each enabled parameter.

The type of markers last selected appear on the display.

NOTE:If you choose My Measure but have not yet set up or enabled any parameters, you will not see

any markers, either.

4. To change the marker type, open any parameter (Px) dialog and in Markers select either:

l Simple - produces cursors and gate posts. The gate posts are independently placeable for each

parameter.

l Detailed - produces cursors, gate posts, a label identifying the parameter being measured, and a

level indicator and hysteresis band for "at level" parameters.

NOTE: The Markers setting is applied to all parameters at the same time. If you choose Simple

markers on any parameter dialog, all parameters are then displayed in this mode.

5. Select the Always On checkbox if you wish to continue to display Help Markers on open traces.

Turn Off Markers

From the Measure setup dialog, choose Help Markers Clear All.

From any Px dialog, choose Markers Off.

Qualified Parameters

Some Teledyne LeCroy software packages give you the ability to constrain parameter measurements to a

vertically or horizontally limited range, or to occurrences gated by a second waveform. Furthermore, both

constraints can operate together. This capability enables you to exclude unwanted characteristics from

your measurements. It is much more restrictive than See "Measure Gate" on page 55 which is used only

to narrow the span of analysis along the horizontal axis.

NOTE: Since this feature operates on only a subset of the data, possible alerts or status indicators

concerning the measurement (such as Data range too low) are not displayed.

Range Limited Parameters

1. From the menu bar, choose Measure → Measure Setup....

2. Touch a Px tab to open its corresponding dialog.

3. Now, on the dialog, touch inside the Source control and select a source from the pop-up.

4. Touch inside the Measure control and select a parameter from the pop-up menu.

5. Touch the Accept tab of the dialog on the right, then touch the Values In Range checkbox.

NOTE: Depending on whether you select a vertical or horizontal parameter, the correct units will be

automatically displayed (V, s, Hz, dB) in the Between and And controls. Or, if you select a simple ratio

parameter (such as power factor) that yields a dimensionless number, no units will be displayed.

6. Touch the Find Range button to quickly display the most recent value of the parameter measurement.
