Signal Labels. The labels for the signals are displayed here. If the
label refers to more than one probe signal, the logical bit number is
added to the label display. If the signal refers to a label in a
compare file, the signal reference is followed by an "x".
You can change the signals displayed and the order they are
displayed at any time. You can also choose to display the signal
level at the cursor ("L" or "H" for low or high, respectively). If this
option is selected, the signal level at the cursor is displayed in the
place of the "> " on the right of the signal label.
Waveform. The waveform depicts the trace data using graphics
characters, or ASCII characters if graphics are not supported. The
waveform is segmented horizontally into divisions. The relative

the magnification. The size of each division is displayed below the
sample period. The relative vertical size of the waveform can be set
to small, medium, or large.
Mode. The mode for the current trace is displayed here.
Sample Period. The sample period for the current trace is

points (interval statistics) or the number of occurrence marks
(abcd) between the mark_x and mark_o points (occurrence
statistics). For each of the two types of analysis, you can choose to
display the range (maximum and minimum), or the mean and
standard deviation. The number of samples (runs) is also displayed.
Reference Points. Four reference points are displayed: the
cursor, the trigger point, and the mark_x and mark_o points. If the
