The waveforms are

displayed in Quad grid

mode. The trend of

t@pit is basically linear,

as expected because

the time at each pit from

the trigger is ascending.

The trend of the pit

widths looks basically

as expected. Notice that

there are exactly as

many events inside both

trends, a necessary

condition.

From the menu bar, select Display Setup… and set the grid mode to XY. Bands of pit widths

corresponding to widths that are ideal integer multiples of the clock period will be evident. Select

F2 (the trend of t@pit) and zoom to expand the time scale. Then select F1 (the trend of pwid)

and use the vertical Z

OOM knob to adjust the band spacing. The vertical POSITION knob can be

used to position the display vertically.

The next screens show the XY plot.
