Introduction

Data Analyzer is a software program for analyzing testing result data sheets by Larson Automation. 

Larson Automation specializes in developing automated test solutions for telecommunications companies’ products. Most of the test stations by Larson Automation generate the standard data sheets to report the testing result. With the ability to be customized by customers, the data sheet provides a flexible and efficient way for business report. 

Based on the advantage, data analyzer is able to summarize thousands of data sheets and to give a user a generalized idea of the tested products quality distribution. It includes some advanced statistical methodologies, such as mean, natural limits, sigma, Histogram distribution, Pareto analysis and etc.

Statistical Analysis

All the result data files are stored into an organized directory system automatically by testing software. Data Analyzer will scan the directory with these data sheets and provides convenient statistical analysis tools.

Pareto Analysis lists all the failed test titles in a descend order. It consists of a graphic and a tabular displays. It is very convenient to user for finding where the major problems locate in production.

Tabular Statistics Collection

The Data Analyzer Controller contains the analyzing actions and the data file statistical result. After scanning the data result directory, the control provides a tabular display of all the tests: user-defined specifications, unit, the number of testing units, the number of failed units, the percentage of good units, average test measurement result, and standard derivation. The table is sortable on the meaningful columns.

With the problem test title, the user is able to perform Histogram Analysis on it. The Histogram Analysis provides the distribution graph crossing all the data files of testing units. Most of the production test results follow the normal distribution. However, some irregular failed units will fall out and they are obviously displayed on the graph. The user can find the failed result numerical value and the data file containing the failure on the Data List box.

Under desirable conditions, the sample data exhibit a normal (Gaussian) distribution.

When failures occur, deviation from the normal distribution becomes quite obvious.

Explore Individual Data File

Locating the data file with the failed test, the user can further explore it on screen or print it in paper. The data sheet file is corresponding to an individual testing unit. It contains more detail information on the tests, such as unit model, test station ID, serial number, testing date and time, and operator name.
