Test apparatus, diagnosing program and diagnosing method therefor
First Claim
1. A test apparatus for testing devices-under-test, comprising:
- a plurality of test modules for supplying a test signal to said device-under-test and receiving an output signal output by said device-under-test corresponding to the supplied test signal;
a test head for carrying a testing performance board that carries said device-under-test and connects said mounted device-under-test with said plurality of test modules; and
a control unit for controlling said plurality of test modules;
wherein said control unit has;
a diagnosing program storage section for storing object diagnosing programs for causing said control unit to control the diagnosis of a certain type of the object test module to be diagnosed per type thereof;
a file storage section for storing a compatible information file recording, per type of the object test module to be diagnosed, identification information of at least one mutually compatible diagnostic performance board to be mounted on said test head instead of said testing performance board to diagnose said object test module to be diagnosed by the respective object diagnosing program;
an identification information obtaining section for obtaining the identification information of said diagnostic performance board when said diagnostic performance board is mounted on said test head; and
an object diagnosing program executing section for executing said object diagnosing program corresponding to the type under the condition that at least one of the identification information recorded in said compatible information file correlatively with the type of said designated object test module to be diagnosed coincides with the identification information obtained by said identification information obtaining section.

Abstract
There is provided a test apparatus having a plurality of test modules. The test apparatus stores object diagnosing programs for controlling diagnosis of the object test module to be diagnosed of a certain type per type of the test module to be diagnosed and stores, separately from it, a set of identification information of diagnostic performance board to be mounted on a test head to diagnose the object test module to be diagnosed by the respective object diagnosing programs per type of the object test modules to be diagnosed. When the diagnostic performance board is mounted on the test head, the test apparatus obtains identification information of the diagnostic performance board and executes the object diagnosing program corresponding to that type under the condition that the identification information coincides with the identification information stored correlatively with the type of the designated object test module to be diagnosed.
