Parameter Description
Range
Calculates range (max min)
a histogram.
Resolution
Ratio of taa for a high and low
frequency waveform
Rise
Rise time: Duration of rising
edge from 10-90%.
Threshold arguments specify
two vertical values on each
edge used to compute rise
time.
Formulas for upper and lower
values:
lower = lower thresh. x
amp/100 + base
upper = upper thresh. x
amp/100 + base
Rise 20-80%
Rise 20% to 80%: Duration
pulse waveform's r
transition from 20% to 80%,
averaged for all rising
transitions between the cursors.
Rise@level
Rise at level: Duration of pulse Duration of rising edges
waveform's rising edges
between transition levels.

Notes
Available with DDM2, JTA2,
and XMAP options.
Standard in DDA-5005A.
Hysteresis argument used to
discriminate levels from noi
in data.
Standard parameter.
On signals not having two
major levels (triangle or saw-
tooth waves, for example), top
and base can default to
maximum and minimum,
giving, however, less
predictable results.
