When the cursor readings are turned on, you can choose one or more measurements as follows:

1.From Scope mode, press to open to the More Scope window.

2.From the second screen page of the More Scope win-

dow, highlight ADD MAIN READING. Press to open the list box. The ADD MAIN READING list box allows you to choose which cursor measurement read- ing to display. A list of possible measurements is shown in Figure 6-1.

3. Choose the type of Scaling Reading: off, ZERO ∆, or %

off

displays the measurement results in normal

values.

displays a change to the reference value.

%

displays a change to the reference value as

 

a percentage.

4.Choose the waveform source with Measure on Wave- form. The source selection is determined by active dis-

play traces. The traces can be obtained from the active display (A, B, A±B) or from waveform memory.

5.Choose the number of Readings; the test tool can display up to five cursor readings at the same time. When you choose another main readings, all readings will shift down one, and your last chosen measurement is placed on top. Notice that the bottom reading is then removed from the display.

Using the Markers

Use the marker to identify the point on the waveform that a measurement has occurred or is expected to occur. The marker appears on the waveform as an "X".

6.From the third screen page of the More Scope window,

press to open the Markers list box. A list box of

markers in use is shown in Figure 6-2. Use or

to choose the marker. Press to select.
