3.6 Dsplayng Computed Results (Statstcs)
Procedure
1. In the waveform display screen, click the tab of the group on which you wish to
perform statistical computation over an area.
2. Click the start point of the computation area in the waveform display area, then
drag the cursor to define the area and end point (use the cursor in the same
manner as in section 3.5, ìDisplaying Cursor Values.”
3. Click the Statistics button on the toolbar. The Statistics dialog box opens.
Channel display

Progress bar
Explanaton
Specify using two cursors the interval over which computation is to be performed.
If the cursors are not displayed, all the data are used in the statistical computation.
The statistical parameters are the minimum value, the maximum value, the P-P value
(maximum - minimum), the mean value, and the rms value. The computation is executed
when the dialog box is displayed, or when you click the Calculate button.
(Channels in Normal format are displayed in a single row. Values of channels in MinMax
format are displayed in two rows, one for the minimum and maximum value at the cursor
position. )
Mn and Max
Shows the maximum and minimum values of the range selected by the cursors, or the
entire range.
PP
Shows the difference between the maximum and minimum values of the range
selected by the cursors, or the entire range.
Mean
Shows the mean values of the range selected by the cursors, or the entire range.
RMS
Shows the RMS values of the range selected by the cursors, or the entire range.
Start Tme and End Tme
Shows the start and end times for computation for each channel.
Progress Bar
Displays the execution status of the computation.
Calculate button
Recalculates the statistics. If you change the positions of cursors while the Statistics
dialog box is open, click this button to refresh the computed results.
Note
• The cursors used to display cursor values and those used to specify the interval for
statistical computation over an area are the same.
• The Statistics dialog box and Cursor Value dialog box can be displayed at the same time.
• The statistical results are not linked to cursor movements or switching of groups. After any
such changes are made, click the Statistics button or the Calculate button to recalculate and
display the results.
