List of Parameters
The following table describes the instrument parameters. Availability of some parameters
depends on the options installed. See the comments in the "Notes" column of the table.
Parameter Description Definition Notes
100BT Fall Fall time between 2 levels
(upper-base, base-lower) of a
3-level signal (100BT)
Available with ENET
option.
100BT Rise Rise time between 2 levels
(Lower-base, base-upper) of a
3-level signal (100BT)
Available with ENET
option.
100BT TIE Difference between the measured
and ideal times at level between
base and upper orlower levels of
100BT signal.
Available with ENET
option.
100BT Tj Total jitter from a TIE at level
between base and upper or lower
levels of 100BTsignal.
Available with ENET
option.
ACSN Auto-correlation Signal-to-Noise
provides a signal-to-noise ratio for
periodic waveforms.
Available with DDM2
option.
Standard in
DDA-5005A.
AltNCycle Alternate N-Cycle Plot. Timing of
the transitions in the data waveform
is measured for each transition and
plotted as a function of the number
of unit intervals over which the
timing is measured. The N-cycle
plot displays the mean or standard
deviation of the edge placement in
the waveform relative to each other
(data to data) or to a reference clock
(clock to data).
Available with ASDA
option.
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
