Check the clock pulse width. Using the oscilloscope, verify that the clock pulse
1
width is 3.480 ns, +20 ps or -80 ps.
a Enable the pulse generator channel 1 and channel 2 outputs (LED off).
b In the oscilloscope Timebase menu, select Scale: 1.000 ns/div.
c In the oscilloscope Timebase menu, select Position. Using the oscilloscope knob,
position the clock waveform so that the waveform is centered on the screen.
d On the oscilloscope, select [Shift] + width: channel 2, then select [Enter] to display the
clock signal pulse width (+ width (2)).
e If the pulse width is outside the limits, adjust the pulse generator channel 2 width until
the pulse width is within limits.
