characteristic of rectangular
waveforms and represents the
higher most probable state
determined from the statistical
distribution of data point values in
the waveform.
domain waveform or
histogram of data of
same waveform. But
with histograms, result
may include
contributions from more
than one acquisition.
Standard parameter.
Total Jitter Total jitter at a given bit error rate Available with ENET
and SDA options.
Total Pop Total population of a histogram. Available with DDM2,
JTA2, XMATH, XWAV,
CAN02, SDA, and
XMAP options.
Standard in
DDA-5005A, SDA100G,
WaveExpert, and
sampling scopes
tUpS Upsamples a time parameter by nX Available with SDA and
SDM options.
TxCmD PCI Express: V
TX-CM-DC-LINE-DELTA
Absolute delta of DC common
mode voltage between D+ and D-
Available with PCIE
option.
TxFall Fall2080 and ParamRescale, to get
UI
Available with PCIE
option.
TxRise Rise2080 and ParamRescale, to
get UI
Available with PCIE
option.
Vcross Voltage at which two signals cross.
That is, voltage of either signal at
the time when difference is zero.
Available with SDA and
PCIE options.
Vdiff Used for V TX-DIFFp-p and V
RX-DIFFp-p for PCI-Express
Available with PCIE
option.
VTxDeRatio Ratio between transition and
de-emphasized bits
Available with PCIE
option.
Width Width of cyclic signal determined by
examining 50% crossings in data
input. If first transition after left
cursor is a rising edge, waveform is
considered to consist of positive
pulses and width the time between
adjacent rising and falling edges.
Conversely, if falling edge, pulses
are considered negative and width
Width of first positive or
negative pulse averaged for
all similar pulses
Similar to fwhm, though,
unlike width, that
parameter applies only
to histograms.
Standard parameter.
