Description
Displays the percentage of points in the histogram that are within two standard deviations of the
histogram mean.
Displays the percentage of points in the histogram that are within three standard deviations of
the histogram mean.
Description
The ratio of eye top to base. This measurement only works for waveform database or a reference
waveform saved in waveform database mode.
The ratio of eye top to base expressed as a percentage. This measurement only works for
waveform database or a reference waveform saved in waveform database mode.
The ratio of eye top to base expressed in decibels. This measurement only works for waveform
database or a reference waveform saved in waveform database mode.
The measurement of the eye height in volts.
The measurement of eye width in seconds.
The top value used in the extinction ratio measurements.
The base value used in the extinction ratio measurements.
The eye crossing point expressed as a percentage of eye height.
The peak-to-peak value for the edge jitter in the current horizontal units.
The RMS value of the edge jitter in the current horizontal units.
Six times the RMS value of the edge jitter in the current horizontal units.
The peak-to-peak value of the noise of the top or base of the signal as specified by you.
The RMS value of the noise of the top or base of the signal as specified by you.
The ratio of the signal amplitude to the noise of the top or base of the signal as specified by you.
The peak-to-peak time variation of the first eye crossing measured at the Mid Ref as a percent of
the eye period.
The ratio of eye size to noise.
