On the 8133A pulse generator, set the Channel 2 pulse
1
width to 1.5 ns.
Observe the 54845A oscilloscope display. Change the
2
Channel 2 pulse width of the 8133A pulse generator so
that the pulse width measured at 1 volt on the
oscilloscope is equal to 1.5 ns minus the measurement
uncertainty and display resolution of the oscilloscope,
further reduced by 35 ps for test margin.
If you are using the 54845A/B oscilloscope, the
measurement uncertainty is ±((0.007% * Δt) + (full
scale/2x memory depth) + 30 ps) = ±30.10 ps. Add 5 ps
for display resolution. Add 35 ps test margin.
1.5 ns - 30.10 ps - 5 ps - 35 ps = 1.43 ns. Set the pulse
width as measured on the 54845A/B oscilloscope to
1.43 ns.
