Display Resolution You get the best resolution by changing the seconds per division (s/Div) to
a value that displays one negative-going edge of both the RAS and CAS
waveforms. Set the s/Div by following these steps.
1. Touch the s/Div field one time (the field will turn light blue) to allow
you to adjust the horizontal scaling with the front-panel knob. Touch
the s/Div field one more time (the field will turn white) and use the
keypad pop-up to select any scaling you desire.
2. While the field is light blue, rotate the knob until your waveform
shows you only one negative-going edge of the RAS and one
positive-going edge of the CAS waveform (see above). In this
example 200 ns is best.
