Analyzing Traces with the Bidirectional Analysis Application

226 FTB-7000 Series

Using Markers to Edit Events

3. Once the appropriate markers are selected, use one of the following

methods to move them along the trace:

³ Drag markers to the desired location directly on the graph using

the stylus or your finger.

³ Use the selection dial (located on the front of the unit).

³ Use the single-arrow buttons.

³ Enter a distance value in the Position box, and press .

Note: Keep in mind that when you work with the B->A trace, the trace is

presented in the opposite direction of the A->B trace, and so are the

markers. For example, instead of having the distance between span start

and A as the first element, you would have the distance between span start

and B. As another example, instead of having the distance between A and

B, you would have the distance between B and A.
