Waveforms in Probe

Cursor 1 is positioned on the first trough (dip) of the V(1)

waveform. Cursor 2 is positioned on the second peak of the

same waveform. In the Probe Cursor box, cursor 1 and cursor 2

coordinates are displayed (A1 and A2, respectively) with their

difference shown in the bottom line (dif). The logic state of the

Out signal is also displayed to the right of the cursor coordinates.

The mouse buttons are also used to associate each cursor with a

different trace by clicking appropriately on either the analog

trace symbol in the legend or on the digital trace name (see

Table 17-2 on page 17-38

). These are outlined in the pattern

corresponding to the associated cursor’s crosshair pattern.

Given the example in Figure 17-11, right-clicking the V(2)

symbol will associate cursor 2 with the V(2) waveform. The

analog legend now appears as shown below.

The Probe Cursor box also updates the A2 coordinates to reflect

the X and Y values corresponding to the V(2) waveform.

To position a cursor on the next

trou

h of a waveform, from the

Tools menu, point to Cursor,

then select Trou

To position a cursor on the next

peak of a waveform, from the

Tools menu, point to Cursor,

then select Peak.
