Diagnostic program, a switching program, a testing apparatus, and a diagnostic method

A switching program of a testing apparatus comprising a plurality of test modules for providing a device under test with a test signal and a control apparatus for controlling the plurality of test modules, the switching program switching a signal for diagnosis input and output software module for making the control apparatus control a test module which is not an object to be diagnosed and which is called from an object diagnostic software module for making the control apparatus diagnose a test module which is the object to be diagnosed, wherein

• said signal for diagnosis input and output software module is provided in each kind of test module which is not the object to be diagnosed and which outputs a signal for diagnosis to the test module which is the object to be diagnosed or makes the control apparatus control the test module which is not the object to be diagnosed so that the signal for diagnosis output by the test module which is the object to be diagnosed is input to the test module which is not the object to be diagnosed, and
• the switching program comprises:
• a kind specification software module for making the control apparatus specify said signal for diagnosis input and output software module which corresponds to the kind of the test module which is not the object to be diagnosed, in response to a call received from said object diagnostic software module which instructs said kind specification software module to receive the signal for diagnosis from or send the signal for diagnosis to the test module which is not the object to be diagnosed;
• and
• a call destination switching software module for making the control apparatus call said signal for diagnosis input and output software module specified said kind specification software module, making the test module which the object to be tested input the signal for diagnosis to the test module which is not the object to be tested, and making the test module which is not the object to be tested output the signal for diagnosis to the test module which the object to be tested.

A testing apparatus for testing a device under test comprising:

• a plurality of test modules for providing the device under test with a test signal;
• and
• a control apparatus for controlling the plurality of test modules diagnostic program of a testing apparatus,
• wherein said control apparatus executes a diagnostic program for diagnosing said test module and thus perform function of an object diagnostic section for making said control apparatus diagnose a test module which is an object to be diagnosed;
• a signal for diagnosis input and output section which is provided in each kind of test module which is not the object to be diagnosed and which makes the test module which is not the object to be diagnosed output a signal for diagnosis to the test module which is the object to be diagnosed or makes the signal for diagnosis output by the test module which is the object to be diagnosed is input to the test module which is not the object to be diagnosed;
• a kind specification section for making said control apparatus specify said signal for diagnosis input and output section which corresponds to the kind of the test module which is not the object to be diagnosed, in response to a call received from the object diagnostic section which instructs the kind specification section to receive the signal for diagnosis from or send the signal for diagnosis to the test module which is not the object to be diagnosed;
• and
• a call destination switching section for making said control apparatus call the signal for diagnosis input and output section specified the kind specification section, making the test module which the object to be tested input the signal for diagnosis to the test module which is not the object to be tested, and making the test module which is not the object to be tested output the signal for diagnosis to the test module which the object to be tested.

A diagnostic method by a testing apparatus comprising a plurality of test modules for providing a device under test with a test signal and a control apparatus for controlling the plurality of test modules, the diagnostic method making the control apparatus diagnose the plurality of test modules and comprising:

• an object diagnostic step of making the control apparatus diagnose a test module which is an object to be diagnosed;
• a signal for diagnosis input and output step which is provided in each kind of test module which is not the object to be diagnosed and which outputs a signal for diagnosis to the test module which is the object to be diagnosed or makes the control apparatus control the test module which is not the object to be diagnosed so that the signal for diagnosis output by the test module which is the object to be diagnosed is input to the test module which is not the object to be diagnosed;
• a kind specification step of making the control apparatus specify said signal for diagnosis input and output step which corresponds to the kind of the test module which is not the object to be diagnosed, in response to a call received from said object diagnostic step which instructs said kind specification step to receive the signal for diagnosis from or send the signal for diagnosis to the test module which is not the object to be diagnosed;
• and
• a call destination switching step of making the control apparatus call said signal for diagnosis input and output step specified said kind specification step, making the test module which the object to be tested input the signal for diagnosis to the test module which is not the object to be tested, and making the test module which is not the object to be tested output the signal for diagnosis to the test module which the object to be tested.
