cross_hist()

Returns jitter histogram

Syntax
y = cross_hist(Vout_time, time_start, time_stop, level_low, level_high, number_of_bins, BitRate, No_of_Eye, Delay, steps)

Arguments

Name	Description	Range	Type	Required
Vout_time	time domain voltage waveform	(-∞, ∞)	real	yes
time_start	define the rectangular window points for jitter histogram plot	[0, ∞)	real	yes
time_stop	define the rectangular window points for jitter histogram plot	[0, ∞)	real	yes
level_low	define the rectangular window points for jitter histogram plot	[0, ∞)	real	yes
level_high	define the rectangular window points for jitter histogram plot	[0, ∞)	real	yes
number_of_bins	defines the number of bins on the time axis of eye diagram and controls the resolution of jitter histogram plot	[1, ∞)	integer	yes
BitRate	bit rate of the channel and is expressed in frequency units	(0, ∞)	real	yes
No_of_Eye	Used for multiple eye jitter histogram plots	[0, ∞)	integer	yes
Delay	used to remove initial transient in the eye diagram and is expressed in time units	[0, ∞)	real	yes
steps	represents the number of sampling points between level_low and level_high and is used for controlling the density of jitter histogram.	[1, ∞)	integer	yes
