Now that you have acquired the RAS and CAS waveforms, you need to

Display Resolution
You get the best resolution by changing the Time/Div to a value that
displays one negative-going edge of both the RAS and CAS waveforms.
Set the Time/Div by following these steps.

1.
Place the cursor on Time/Div and press SELECT . The Time/Div
pop-up appears, showing you the current setting.
2. While the pop-up is present, rotate the KNOB until your waveform
shows you only one negative-going edge of the RAS waveform and
one positive-going edge of the CAS waveform (see above). In this
example 200 ns is best.
