ABSTRACT:
The present invention provides a test apparatus which comprises: a test head which applies a test pattern to the electronic device; a main frame which includes multiple frame-side connectors and which supplies control signals to the test head via the frame-side connectors; and a cable unit which provides optical connection between the frame-side connectors and the test head, and which transmits the control signals to the test head. With such an arrangement, the cable unit comprises: multiple optical fiber cables which transmit the control signals; multiple unit-side connectors which are provided at the ends of the optical fiber cables, and which are provided corresponding to the multiple frame-side connectors; a unit fixing portion which fixes the cable unit to the main frame; and a connector holder which holds the unit-side connectors in a manner which enables each unit-side connector to be inserted/extracted into/from the frame-side connector independent of each other.
