cIn the oscilloscope Measure menu, select Measure Chan 2, then select Period. If the
period is more than or equal to 20.000 ns, go to step 4. If the period is less than 20.000
ns but greater than 19.75 ns, go to step 3.
dIn the oscilloscope Timebase menu, add 10 ns to the delay.
eIn the oscilloscope Measure menu, select Period. If the period is more than or equal to
20.000 ns, decrease the pulse generator Chan 2 Doub in 100-ps increments until one of
the two periods measured is less than 20.000 ns but greater than 19.75 ns.
3Check the data pulse width. Using the oscilloscope, verify that the data pulse width
is 3.50 ns, +0 ps or −100 ps.aEnable the pulse generator channel 1 and channel 2 outputs. Leave channel 2 output
disabled.
bIn the oscilloscope Timebase menu, select Sweep Speed 1.00 ns/div.
cSelect Delay. Using the oscilloscope knob, position the data waveform so that the
waveform is centered on the screen.
dIn the oscilloscope Delta V menu, set the Marker 1 Position to Chan 1, then set Marker
1 at −1.3000 V. Set the Marker 2 Position to Chan 1, then set Marker 2 at −1.3000 V.
eIn the oscilloscope Delta T menu, select Start On Pos Edge 1. Select Stop on Neg
Edge 1.
fSelect Precision Edge Find.
gIf the pulse width is outside the limits, adjust the pulse generator channel 1 width and
select the oscilloscope Precision Edge Find until the pulse width is within limits.
