F8 is the p eak-t
o-peak amplitude of the periodic jitter occurring at a rate of Fb
(data rate) divided by 8. This measurement is made across the entire record.
HIGH (Eye High) is the amplitude of a h igh (1) bit measured at a user specified
location within the recovered unit interval. This measurement is made on each
high bit in the record.
HEIGHT (Eye Height) is the minimum vertical eye opening at the center of the
recovered unit interval. This measurement is made across the entire record.
HEIGHTBER (Eye Height@BER) is the predicted vertical eye opening that will
be violated
with a probability equal to the bit error rate. This measurement is
made across the entire record.
HIGH
HIGHTIME (High Time) is the time the signal remains above the Top reference
level (RT). This measurement is made on each cycle in the record.
HOLD (Hold Time) is the time between the specified Mid reference level crossing
(RM) on the Clock source to the closest specified Mid reference level (RM)
crossing on the Data source. This measurement is made on each specified Clock
edge in t
he record.
JITTERSUMMARY (Jitter Summary) is a group consisting of the following
measurements: TIE, TJ@BER, Eye Width@BER, Eye Height@BER, RJ-δδ,
DJ-δδ, PJ, DDJ, DcD, F/2, F/4, F/8.
J2 is the total jitter at a bit error rate of 2.5e-3 (TJ@2.5e-3). This measurement is
made across the entire record.
J9 is the total jitter at a bit error rate of 2.5e-10 (TJ@2.5e-10). This measurement
is made across the entire record.
LOW (Eye Low) is the amplitude of a low (0) bit measured at a user specified
location within the recovered unit interval. This measurement is made on each
low bit in the record.
LOWTIME (Low Time) is the time the signal remains below the Base reference
level (RB). This measurement is made on each c ycle in the record.
MAXimum is the maximum data point. This measurement can be made across the
entire record, or on each cycle in the record.
MEAN is the arithmetic mean of the d ata points. This measurement can be made
across the entire record, or on each cycle in the record.
MINImum is the minimum data point. This me asurement can be made across the
entire record, or on each cycle in the record.
NDUty (Negative Duty Cycle) is the ratio of the Negative Pulse Width to the
Period. This mea surement is made on each cycle in the record.
Negative Duty Cycle = (Negative Width) / Period × 100%
