Parameter Description
Edge@level
Number of edges in waveform.
Excel
Performs measurements in Excel
by transferring one or two
waveforms and reading the
resulting parame
Fall time
Fall time: Duration of falling edge
from 90-10%.
Threshold arguments specify two
vertical values on each edge used
to compute fall time. Formulas for
upper and lower values:
lower = lower thresh. x amp/100 +
base
upper = upper thresh. x amp/100 +
base
Fall 80-20%
Fall 80-20%: Duration of pulse
waveform's falling transition from
80% to 20%, averag
transitions between the cursors.
Fall@level
Fall at level: Duration of pulse
waveform's falling edges betwe
user-specified transition levels. See
also Rise@level.

Indicates location of l eft cursor.
Cursors are interchange
example, the left cursor may be
moved to the right of the right
cursor and first will give the
location of the cursor formerly on
the right, now on left.
