Inspection apparatus and inspection method thereof

An inspection apparatus, for inspecting a first electronic device and a second electronic device, comprising:

• a first signal transfer unit, adapted to receive a first input signal with a first signal input specification;
• a second signal transfer unit, adapted to receive a second input signal with a second signal input specification, wherein the first signal input specification differs from the second signal input specification;
• a first signal output unit, wherein the first signal output unit is selectively coupled to the first signal transfer unit or the second signal transfer unit, wherein the first signal output unit is adapted to be coupled to the first electronic device to output a first output signal with a first signal output specification, and to inspect the first electronic device;
• and
• a second signal output unit, wherein the second signal output unit is selectively coupled to the first signal transfer unit or the second signal transfer unit, wherein the second signal output unit is adapted to be coupled to the second electronic device to output a second output signal with a second signal output specification, and to inspect the second electronic device, wherein the first signal output specification differs from the second signal output specification,
• wherein the first signal transfer unit comprises a first signal transfer board, the second signal transfer unit comprises a second signal transfer board, the first signal output unit comprises a first signal output board, the second signal output unit comprises a second signal output board, the first signal transfer board comprises a first transfer board coupling portion, the second signal transfer board comprises a second transfer board coupling portion, the first signal output board comprises a first output board coupling portion, the second signal output board comprises a second output board coupling portion, the first transfer board coupling portion is selectively coupled to the first output board coupling portion or the second output board coupling portion, and the second transfer board coupling portion is selectively coupled to the first output board coupling portion or the second output board coupling portion.
