HP 16510B, 16500A manual RAS and CAS Signals

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.

Figure 7-8. RAS and CAS Signals

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.
