Set up the test equipment
horizontal center of the graticule line is at 1 volt because the vertical offset
was set to 1 volt in the oscilloscope setup described on page 43.
6 Select Close in the Probe Setup window.
7 Select Close in the Channel Setup window.
Adjust the measured pulse width to 1.5 ns
The pulse generator’s pulse width was set to 1.5 ns (in the setup on page 42). In
this procedure, you will use the oscilloscope’s measurement markers to measure
the actual pulse width in the test setup. Then you will adjust the pulse generator
so that the measured pulse width is as specified.
1 Observe the 54845A oscilloscope display. Change the 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
