Amplitude Measurements panel (optional).
Measurement Description
AC Common Mode (Pk-Pk) The peak-to-peak of the common mode voltage of the two specified sources.
The measurement is taken on the entire record.
Bit Amplitude The difference between the amplitudes of the 1 and 0 bits surrounding a transition. The
amplitude is measured over a specified part of at the center of the recovered time interval.
The measurement is taken on each transition bit of the entire record (Mean) or on the entire
record (Mode).
Bit High
The amplitude of a 1 bit, measured over a specified percent of the center of the recovered time
interval.
The measurement is taken on each high bit of the entire record (Mean) or on the entire record
(Mode).
Bit Low The amplitude of a 0 bit, measured over a specified percent of the center of the recovered time
interval.
The measurement is taken on each low bit of the entire record (Mean) or on the entire record
(Mode).
DC Common Mode The arithmetic mean of the common mode voltage of two sources.
The measurement is taken on the entire record.
Differential Crossover The voltage level of a differential signal pair at the crossover point(s).
The measurement is taken at each crossover point in the record.
T/nT Ratio The ratio of a nontransition bit voltage (second and subsequent bit voltage after a transition) to
its nearest preceding transition bit voltage (first bit voltage after the transition). Bit voltage is
measured at the interpolated midpoint of the recovered unit interval.
The measurement is taken on each nontransition bit in the record.
Timing Measurements panel (optional).
Measurement Description
SSC Freq Dev The spread spectrum clock frequency deviation. This measurement enables a time trend plot of
the spread spectrum clock modulation profile.
The measurement is taken on each cycle of the entire record.
SSC Modulation Rate The modulation frequency of a spread spectrum clock.
The measurement is taken on each cycle of the entire record.
