Specifying a

Trigger

Condition

HP 16510B Front-Panel Reference

To capture the data and then place the data of interest in the center of the display of the timing waveform menu, you need to tell the logic analyzer when to trigger. Since the first event of interest is when the LRAS is asserted (negative-going edge of RAS), you need to tell the logic analyzer to trigger on a negative-going edge of the RAS signal.

1.Display the Timing Trace Specification menu.

a.Touch the field second from the left in the upper left corner.

b.When the pop-up appears, touch the Trace 1 field.

2.Set the trigger so that the logic analyzer triggers on the negative-going edge of the RAS.

a.Touch the Then find Edge field under the label RAS.

b.When the pop-up appears, touch the field with the arrow pointing down. This selects a negative-going edge. Touch DONE when your selection is complete.
