Explanation

Displaying the statistic values

The window displaying a histogram or the area enclosed by the markers can be set as the area to
be used for statistical computation.  For details, refer to 7.1.

• Time stamp mode

• No computation is carried out for jitter 1 (

σ

/T) and jitter 2 (MELE), so asterisks “*” will be

displayed.

Statistical computation item Statistic value Statistical computation area

(The entire window is used for 
statistical computation in this 
example.  “MARKER” will be 
displayed if the area enclosed 
by the markers is used for statistical 
computation.)

No computation is carried out for jitter 1 and jitter 2.

• Hardware histogram mode

A bar graph indicating the standard deviation s is displayed below the list.  The bar graph range

(maximum value) can be selected (see below).

Statistical computation item Statistic value

Statistical computation area

(The area enclosed by the markers 
is used for statistical computation 
in this example.  “WINDOW” will be 
displayed if the entire window is 
used for statistical computation.)

Standard deviation 

σ

 is displayed 

in bar graph.

Bar graph range (maximum value)

Note

Statistic values are obtained as a result of computation of data present inside the window or the area

enclosed by the markers.  Asterisks “*” will be displayed instead of static values if no histogram exists

inside the window or the area enclosed by the markers.

Setting constant T

Constant T is used for computation of jitter 1 and jitter 2 in the case of hardware histogram mode.
Setting range: 10 to 999.9 ns

Note

The same constant T is used for both histogram display function (see 7.1) and this statistics display

function.  In addition, it is also used for pulse width measurement (see 5.4).

• Selecting the polarity to be used for display/statistical computation

The same menu as the one displayed when 

 is selected as the polarity for pulse width

measurement is displayed.  (It is also the same menu as the calculation menu displayed in 7.1).
Select the desired polarity from the following to be used for statistical computation.
•

: Performs statistical computation for the positive side only.

•

: Performs statistical computation for the negative side only.

•

: Performs statistical computation for the both positive and negative sides.  However,

computation results will be as follows.
• Maximum, minimum, average, peak to peak, flutter, jitter 2: Not computed and asterisks “*”

are displayed instead of the statistic values.

• Standard deviation, jitter 1: Standard deviation (

σ

) and jitter 1 (

σ

/T) are computed,

individually for positive and negative sides, then the sum of computed standard deviation and
that of computed jitter 1 are divided by 2.

Selecting the bar graph range

The standard deviation (

σ

) is displayed in a bar graph only when the statistic display function is

ON in hardware histogram mode.  The maximum bar graph range can be selected from the
following.
7.5/15/30/60 ns
