Figure 11.24 shows the parameters of a square wave being measured using
Software Oscilloscope. The horizontal (X) cursors are placed at equivalent
points on successive cycles and the time difference between then is calculated
and displayed (approximately 20 ms). A similar process using the vertical (Y)
cursors can be used to determine the peak and peak-peak voltage. Cursors can
