PROBLEM TO BE SOLVED: To enable an inspection of a light reception unit that includes a reception circuit in which amplifier circuits amplifying an electric signal input from a side of a light reception element and outputting the amplified electric signal are multistagedly connected.SOLUTION: An inspection device comprises: a signal generation unit that generates an input signal to be input to each partial circuit serving as an inspection unit, letting each of partial circuits obtained by partitioning a reception circuit into a plurality of segments so as to include at least one amplifier circuit be the inspection unit; a first processing unit that acquires an output signal output from each partial circuit with respect to the input signal, and performs processing for checking an amplification factor for each partial circuit on the basis of the input signal and output signal; and a second processing unit that inputs an inspection optical signal to the light reception element, and performs processing for checking an operation of a light reception unit on the basis of a signal output from the reception circuit.

    【課題】受光素子側から入力された電気信号を増幅して出力する増幅回路が多段接続された受信回路を含む受光部の検査を行うことを可能とする。【解決手段】検査装置は、少なくとも一つの増幅回路を含むようにして受信回路を複数に区画した部分回路を検査単位として、この検査単位となる各部分回路へ入力させる入力信号を生成する信号生成部と、前記入力信号に対して部分回路それぞれから出力される出力信号を取得し、これら入力信号と出力信号とに基づいて部分回路毎の増幅率を確認するための処理を行う第1処理部と、検査用の光信号を前記受光素子に入力して前記受信回路から出力される信号に基づいて受光部の動作を確認するための処理を行う第2処理部と、を備えている。【選択図】 図1
