X-Stream Operator’s Manual
WM-OM-E Rev I 185
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..
Avg Power Average power of the waveform Available with SDA and
SDM options.
Standard in SDA100G
scopes.
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.
Bit Rate One over duration of one UI
measured on an eye
Available with SDA
option.
Standard in SDA,
SDA100G, and
WaveExpert scopes.
CMACp PCI Express V TX-CM-ACp and V
RX-CM-Acp
Available with PCIE
option.
Cycles Determines number of cycles of a
periodic waveform lying between
cursors. First cycle begins at first
transition after the left cursor.
Transition may be positive- or
negative-going.
Number of cycles of periodic
waveform
Standard parameter.
cyclic
Mean
Cyclic mean: Computes the
average of waveform data. Contrary
to mean, computes average over an
integral number of cycles,
eliminating bias caused by
fractional intervals.
Average of data values of an
integral number of periods
Choose this parameter
by selecting Mean from
the parameter table,
then touching the Cyclic
checkbox.
Standard parameter.
