HLocate the time referencepoints for these waveforms by first
identifying the point where the rising edgeof the left-most wave-
form crossesthe center horizontal graticule line, then note the
correspondingt ime referencepo int for the right-most waveform.See
Figure 2--14.
HPressCURSORS and select the V Bars Cursors Type; then clickthe
Close button.
HAlign one V bar cursor to the time reference point of the left-most
waveformedge and the other cursor to the time reference point of the
right-most waveformedge by rotating the multipurpose knobs (if
necessary,press the FINE buttons). See Figure 2--14.
