Data Logging for Statistical Analysis

Perform the following steps to log the data to be used in statistical analysis.
Step 1. From the seven parameters (measurement parameter 1, measurement parameter 2,
measurement parameter 3, measurement parameter 4, test signal voltage level monitor
value (I-mon), test signal current level monitor value (V-mon), and DC resistance
measurement value (Rdc)), select the parameters for statistical analysis and display them
on the single point measurement display or on the list measurement display.
NOTE
Parameters displayed on the measurement display are subjected to statistical analysis.
Accordingly, make sure that parameters that should not be subjected to statistical analysis
are not displayed on the measurement display. For how to turn the parameter display off,
see Chapter 7, "Executing Measurements and Displaying Results," on page 155.
When measuring with multiple measurement points on the list measurement display, each
of the measurement points are subjected to statistical analysis.
Step 2. Press the
trigger mode softkey menu.
Step 3. Select
menu.
Select MAX LOG SIZE [ ] from the softkey menu to display the Data Logging Size input
window (Figure 9-1).

Step 4. Enter the data logging size by clicking the number keys in the window. When done, click
the
Enter
NOTE
A single data logging size is required for all parameters in the same measurement. For
example, if seven parameters are displayed in the single point measurement display and list
measurement with four measuring points are to be performed with 1000 data logged for
each point, it is necessary to set the data logging size to 7 × 4 × 1,000 = 28,000.
The data logging size can be set to a maximum of 2,400,000 (points).
Step 5. Select
