Test Method Overview

As explained in Units 3 and 4, the 93000 system provides standard
mixed-signal tests for DAC and ADC as the testfunctions. These
can be executed by using the Test Flow Editor.
In addition, to perform tests that are not provided, the test
programs can be created as test method programs by using the the
C++ language and customized functions.
The customized functions are called test method API (Application
Programming Interface). These have the following capabilities:
•Changing measurement conditions for the tester hardware
•Executing the test with the measurement conditions
•Calculating the basic characteristics in the time domain and
frequency domain from the measured data
•Judging the calculated result as pass or fail by referring to limit
values
You can set up a test suite that consists of a test method in similar
way to testfunctions, on the Test Flow Editor.
To enable a test method to call on the Test Flow Editor, you must
perform the following tasks at least for the test method:
1. Setting up input parameters and identifiers for limit
values that will be used in the test method program.
2. Programming the test method program.
3. Compiling and linking the test method program.
4. Registering the test method program to be called from
the Test Flow Editor
5. Debugging the test method program
For details about these tasks, see Lesson 2 in this unit.
The following figure shows the relationship of the test method-
based test suite, tester hardware, and test method program:
