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 P
OSITION
knob can be
used to position the display vertically.
The next screens show the XY plot.
