Testing Performance

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

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.

a Enable the pulse generator channel 1 and channel 2 outputs. Leave channel 2 output disabled.

b In the oscilloscope Timebase menu, select Sweep Speed 1.00 ns/div.

c Select Delay. Using the oscilloscope knob, position the data waveform so that the waveform is centered on the screen.

d In 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.
