Display Softkey
The Display softkey selects one of three display modes: normal, averaged,
and envelope.
Norm (Normal) The normal mode allows you to view each captured
segment individually. The viewable segments are determined by the
include exclude softkey.
When norm is selected, the function key below the display softkey is
activated. This field displays the current segment number being viewed, and
is set using either the knob or keypad. Selecting a segment number larger
than the maximum captured causes all segments to be displayed (overlayed),
where all the included segments from the selected source are displayed at
one time. Selecting an excluded segment causes "segment X is excluded" to
be displayed.
Measurements are performed using the newest data in each pixel column.
Avg (Average) The average mode averages each captured segment
into a composite waveform. Only segments selected as included using
the exclude include softkey are averaged. When average is selected, the
segment number currently being averaged is displayed in the lower left
corner of the screen, and the number of segments softkey is activated.
The number of segments key displays the total number of segments that
were averaged.
Env (Envelope) The envelope mode displays the minimum and
maximum voltages in each captured segment. Only segments selected as
include using the exclude include softkey are used. When envelope is
selected, the segment number currently being evaluated is displayed in
the lower left corner of the screen, and the number of segments softkey
displays the total number of segments that were used.
