Claims
- 1. A test apparatus for testing an electronic device, comprising:
a test module for sending and/or receiving a test signal to and/or from said electronic device; a test head comprising a plurality of TH slots for detachably holding said test module; a diagnosis module for performing diagnosis of said test module; and coupling means comprising a plurality of PB slots being electrically coupled to said TH slots respectively for detachably holding said diagnosis module, wherein said diagnosis module held in one of said PB slots diagnoses said test module held in one of said TH slots being electrically coupled to said one said PB slots.
- 2. A test apparatus as claimed in claim 1, wherein said coupling means is a performance board being detachably held by said test head.
- 3. A test apparatus as claimed in claim 1, wherein each of said TH slots comprises a same type of connector so that said test module can be coupled to any of said TH slots, each of said PB slots comprises a same type of connector so that said diagnosis module can be coupled to any of said PB slots, and said TH and PB slots have a same type of electrically coupling pattern.
- 4. A test apparatus as claimed in claim 1, wherein said coupling means comprises:
a memory for correspondingly storing identification information of said test module and identification information of said diagnosis module diagnosing said test module; a test module identification information obtaining unit for obtaining said identification information of said test module from said test module; a diagnosis module identification information obtaining unit for obtaining said identification information of said diagnosis module from said diagnosis module; and an identification information comparing unit for comparing said identification information obtained by said test module identification information obtaining unit with said identification information obtained by said diagnosis module identification information obtaining unit, and checking whether said memory stores said identification information in a corresponding manner or not, and wherein said test apparatus continues electrically coupling said test module and said diagnosis module, if said memory correspondingly stores said identification information obtained by said test module identification information obtaining unit and said identification information obtained by said diagnosis module identification information obtaining unit, and electrically disconnects said test module and said diagnosis module, if said memory does not correspondingly store said identification information obtained by said test module identification information obtaining unit and said identification information obtained by said diagnosis module identification information obtaining unit.
- 5. A test apparatus as claimed in claim 1, wherein said diagnosis module comprises:
a memory for storing identification information of said test module to be diagnosed by said diagnosis module; a test module identification information obtaining unit for obtaining said identification information of said test module from said test module; and an identification information comparing unit for comparing said identification information obtained by said test module identification information obtaining unit with said identification information stored in said memory, and wherein said coupling means, said test module or said diagnosis module continues electrically coupling said test module and said diagnosis module, if said identification information obtained by said test module identification information obtaining unit and said identification information stored in said memory coincide, and electrically disconnects said test module and said diagnosis module, if said identification information obtained by said test module identification information obtaining unit and said identification information stored in said memory do not coincide.
- 6. A test apparatus as claimed in claim 1, wherein said test module comprises:
a memory for storing identification information of said diagnosis module used for diagnosis of said test module; a diagnosis module identification information obtaining unit for obtaining said identification information of said diagnosis module from said diagnosis module; and an identification information comparing unit for comparing said identification information obtained by said diagnosis module identification information obtaining unit with said identification information stored in said memory, and wherein said coupling means, said test module or said diagnosis module continues electrically coupling said test module and said diagnosis module, if said identification information obtained by said diagnosis module identification information obtaining unit and said identification information stored in said memory coincide, and electrically disconnects said test module and said diagnosis module, if said identification information obtained by said diagnosis module identification information obtaining unit and said identification information stored in said memory do not coincide.
- 7. A test apparatus as claimed in claim 1, wherein said diagnosis module is held in two of said PB slots so as to be electrically coupled to both said test modules for signal input and output, and performs diagnosis of said test modules for signal input and output.
- 8. A test apparatus as claimed in claim 1, wherein said diagnosis module is held in a plurality of said PB slots so as to be electrically coupled to a plurality of same type of said test modules, and performs diagnosis of said test modules.
