Chapter 3: Testing Performance

To test the single-clock, multiple-edge, state acquisition

2Check the data pulse width. Using the oscilloscope, verify that the data pulse width is 3.000 ns, +0 ps or 100 ps:

a In the oscilloscope Timebase menu, select Scale: 1.000 ns/div.

b In the oscilloscope Timebase menu, select Position. Using the oscilloscope knob, position the data waveform so that the waveform is centered on the screen.

c On the oscilloscope, select [Shift] + width: channel 1, then select [Enter] to display the data signal pulse width (+ width(1)).

d If the pulse width is outside the limits, adjust the pulse generator channel 2 width until the pulse width is within limits.
