Evaluation of the Waveform
Instantaneous values from transients can be observed using the cursors feature of the
Oscilloscope (menu Edit > Cursors).
As long as the cursors are enabled (Edit > Cursors), the two pointers or cursors A and B
are shown in the black box of the Oscilloscope with their standard configuration options, as
shown in Figure 6-22. The cursors can be moved with the mouse (click + hold + drag)
along the curve of the transient from the Channel they are configured. When the cursors
are moved, the user can see the instantaneous value of the curve at the time (dt) where
they are placed (Figure 6-22). If the instantaneous value from another Channel is object of
interest, the channel selection for the cursors A and/or B can be changed on the
Oscilloscope window itself (see Figure 6-22).
