Commands listed in alphabetical order
RISESLEWRATE
(Rising Slew Rate) is the rate of change in voltage as an edge
transitions from the Base reference level (RB) to the Top reference level (RT).
This measurement is made on each cycle in the record.
RISETIME
Rise Time is the time required for an edge to rise from the Base
reference level (RB) to the Top reference level (RT). This measurement is made
on each cycle in the record.
RJ
(random jitter) is the RMS magnitude of all random timing errors following a
Gaussian distribution. This measurement is made across the entire record.
RJDIRAC
(dual-dirac random jitter) is random jitter based on a simplifying
assumption that the histogram of all deterministic jitter can be modeled as a
pair of equal-magnitude Dirac functions. This measurement is made across the
entire record.
RMS
is the true Root Mean Square of the data points. This measurement can be
made across the entire record, or on each cycle in the record.
SRJ
(sub-rate jitter) is the composite jitter due to periodic components at 1/2, 1/4
and 1/8 of the data rate. This measurement is made across the entire record.
SSCFREQDEV
(SSC Frequency Deviation) is the spread spectrum clock frequency
deviation. This measurement enables a time trend plot of the spread spectrum
clock modulation pro
fi
le. This measurement is made on each cycle in the record.
SSCMODRATE
(SSC Modulation Rate) is the modulating frequency of a spread
spectrum clock. This measurement is made on each cycle in the record.
SETUP
(Setup Time) is the time between the speci
fi
ed Mid reference level (RM)
crossing on the Data source to the closest speci
fi
ed Mid reference level (RM)
crossing on the Clock source. This measurement is made on each speci
fi
ed Clock
edge in the record.
SKEW
Skew is the time between the speci
fi
ed Mid reference level (RM) crossing
on one source to the following speci
fi
ed Mid reference level (RM) crossing on a
second source. This measurement is made on each cycle in the record.
TIE
(time interval error) is the difference, in time, between an edge in the source
waveform and the corresponding edge in a recovered reference clock. This
measurement is made on each edge in the waveform.
TIMEOUTSIDELEVEL
Time Outside Level is the time the signal remains above
the Top reference level (RT) and/or below the Base reference level (RB). This
measurement is made on each occurrence in the record.
TJBER
(total jitter at a speci
fi
ed bit error rate) is the predicted peak-to-peak
amplitude of jitter that will only be exceeded with a probability equal to the bit
error rate. This measurement is made across the entire record.
TNTRATIO
T/nT Ratio is the ratio of a non-transition bit voltage (2nd and
subsequent bit voltage after a transition) to its nearest preceding transition bit
voltage (1st bit voltage after the transition). Bit voltages are measured at the
