Parameter Description
Definition
Notes
Amplitude
Measures the difference
between upper and lower
levels in two-level signals.
Differs from pkpk in that
noise, overshoot,
undershoot, and ringing do
not affect the measurement.
top base
On signals not having
two major levels (such
as triangle or saw-tooth
waves), returns same
value as pkpk.
Standard parameter.
Ampl asym
Amplitude asymmetry
between taa+ and taa-
1 - |(taa+ - taa-)|/(taa+
taa-)
Hysteresis argument
used to discriminate
levels from noise in
data.
Available with DDM2
option.
Standard in
DDA-5005A.
ACSN Auto-correlation
Signal-to-Noise provides a
signal-to-noise ratio for
periodic waveforms.
Available with DDM2
option.
Standard in
DDA-5005A.
Area
Integral of data: Computes
area of waveform between
cursors relative to zero level.
Values greater than zero
contribute positively to the
area; values less than zero
negatively.
Sum from first to last of
data multiplied by
horizontal time between
points
Standard parameter..
Base
Lower of two most probable
states (higher is top).
Measures lower level in
two-level signals. Differs
from min in that noise,
overshoot, undershoot, and
ringing do not affect
measurement.
Value of most probable
lower state
On signals not having
two major levels
(triangle or saw-tooth
waves, for example),
returns same value as
min.
Standard parameter.
Cycles
Determines number of cycles
of a periodic waveform lying
between cursors. First cycle
begins at first transition after
the left cursor. Transition
Number of cycles of
periodic waveform
Standard parameter.
