Histogram Summary View

The data represent values from histograms of measurements. Normal Histogram shows statistics from a

single histogram. Accumulated Histogram shows statistics from all histograms since a clear. The user is able

to annotate this page.

If TailFit is enabled, additional values are shown:

- L

RMS

, R

RMS

, Avg

RMS

, DJ, TJ and Goodness of Fits

- L

RMS

is the RMS value from the Gaussian fitted to the left tail.

- R

RMS

is the RMS value from the Gaussian fitted to the right tail.

- Avg

RMS

is the average of the L

RMS

and R

RMS

values.

- DJ is calculated between the means of the fitted Gaussians on the histogram.

- TJ is calculated from the RJ and DJ components at a specific BER.

- Goodness of Fits is CHI Square value. Lower numbers indicate better confidence in RJ values.
