50% point between the local
baseline and the local peak. used to discriminate
levels from noise in
data.
Available with DDM2
option.
Standard in
DDA-5005A.
Range Calculates range (max min)
of a histogram. Available with DDM2,
JTA2, and XMAP
options.
Standard in
DDA-5005A.
Resolution Ratio of taa for a high and
low frequency waveform taa (HF)/mean taa
(LF)*100 Hysteresis argument
used to discriminate
levels from noise in
data.
Standard parameter.
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
Time at lower threshold
minus
Time at upper threshold
averaged over each
rising edge
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.
Standard parameter.
