This formula describes a bell-shaped Gauss curve. If μ is zero and σ varied, you
would get the curves illustrated in the figure below:
The height and position of a normal distribution can be specified in terms of two
parameters: μ and σ. The parameter μ is the mean, the parameter σ is the standard
deviation.
The Gaussian marker shows such a curve. Position, height, and width of this curve
can be changed by dragging the handles, and the actual parameter values are
displayed.
The marker has three handles that can be dragged: two for adjusting its width, one
for changing its height and position.
The following figure shows an exemplary DUT Output Timing/Jitter measurement
result with a Gaussian marker.
The marker readout provides the following information:
