with that particular knob. For instance, if you push one of the vertical
position/offset knobs, offset will be set to 0.0 V for that input channel. If
you push the horizontal position/delay knob, delay relative to trigger will
be set to 0.0 seconds. If you push the trigger level knob, the scope will
automatically set the trigger level to approximately 50%.

Let's now use the scope's "cursors" function to measure the positive pulse
width and peak- to- peak voltage of this waveform. First, visually locate the
"Cursors" knob in the Measure section of the front panel as shown in

Push the Cursors knob; then rotate this knob until "X1" is highlighted;
then press again to select (if you don't press the knob a second time
after dialing to the "X1" cursor, a time- out will occur and then the X1
cursor will automatically be selected and the menu will close).
Turn the Cursors knob until the X1 cursor (#1 timing marker)
intersects with a rising edge of the pulse.
Push the Cursors knob again; rotate this knob until "X2" is highlighted;
then press again to select.
Turn the Cursors knob until the X2 cursor (#2 timing marker)
intersects with the next falling edge of the same pulse.
Push the Cursors knob again; rotate this knob until "Y1" is highlighted;
then press again to select.
Turn the Cursors knob until the Y1 cursor (#1 voltage marker)
intersects with the negative peak of the pulse.
Push the Cursors knob again; rotate this knob until "Y2" is highlighted;
then press again to select.
Turn the Cursors knob until the Y2 cursor (#2 voltage marker)
intersects with the positive peak of the pulse.
