PDUty measures
the percentage of the waveform's +Width relative to its
Period or Bit Time.
NDUty measure
s the percentage of the waveform's -Width relative to its
Period or Bit Time.
BURst measu
res the time between the first and last crossings, either
positive or negative, of the waveform at the mid-reference level within the
measurement region.
RMSJitter measures the one standard deviation (s) of the time variance
where the waveform crosses the mid-reference level.
PKPKJitter measures the delta between the minimum and maximum of time
crossings at the mid-reference level.
DELay measures the time interval between the crossings of the mid-reference
levels on the two sources of the measurement.
PHAse measures the Amount of lead or l ag of one measurement source
relative to a second measurement source. Phase is expressed in degrees,
where 360° comprise one cycle or one bit of the waveform.
AREa measures the area under the waveform curve within the measurement
region.
CARea measures the area under the curve for the first bit or period of the
waveform.
EXTINCTDB measures the ratio of logic 1 to logic 0 expressed in decibels (dB).
EXTINCTPCT measures the ratio of logic 0 to logic 1 expressed in percentage
(%).
EXTINCTRATIO measures the ratio of logic 1 to logic 0 expressed as a s imple
ratio.
EXTINCTCAL precisely measures the ratio of logic 1 to logic 0 expressed in
decibels (dB). The precision measurement is only a vailable with the use an
optical module with the Calibrated Extinction Ratio option.
EYEHeight measures the vertical eye opening of the waveform guard-banded
by ± 3s, measured over the eye aperture.
EYEOfactor measures the horizontal eye opening of the waveform
guard-banded by ± 1s, m easured over the eye aperture.
EYEWIdth measures the horizontal eye opening of the waveform
guard-banded by ± 3s, measured at the mid-reference level.
PCTCROss measures the height of eye crossing as a percentage of eye height
measured in the eye aperture.
LEVCROss measures the mean waveform amplitude at the eye crossing.
