SELECT: Select this button to select UPPER or LOWER for envelope design.
ENVELOPE POINTS: This sets the desired number of envelope points.
AMPLITUDE OFFSET: Use to define how far away from the trace to place the upper or
lower envelope. For an upper envelope, usually the offset will be positive in order to place
the envelope above the signal. For a lower envelope, the offset will usually be negative in
order to place the envelope below the signal.
SHAPE: Use to choose whether the upper or lower envelope will be with flat tops
(SQUARE setting) and vertical lines, or whether the envelope will have sloped lines
(SLOPE setting) between adjacent inflection points. When the square envelope type is
selected, two inflection points are used for each horizontal segment.
SET ENVELOPE: Select this button to generate the envelope using the set
characteristics. If the default results are not satisfactory, you can make adjustments to the
amplitude and frequency of each inflection point, and you can add or delete inflection
points.
