INSPECTION JIG FOR MICROWAVE MULTIPLEX WIRELESS DEVICE

To provide an inspection jig for a microwave multiplex wireless device, which is easy to be installed and has few errors.SOLUTION: An inspection jig 1 bypass-connects an output unit A of a frequency conversion unit 113 and an input unit D of an amplification unit 114 at the time of inspection of a microwave multiplex wireless device 10. The microwave multiplex wireless device comprises: a first cable L1 that connects the output unit A and an input unit B of a switch unit 102; a second cable L2 that connects an output unit C of a hybrid unit 103 and the input unit D; and a third cable L3 that connects an output unit E of the amplification unit 114 and an input unit FL3 of a filter unit 115. The inspection jig comprises: a bypass cable 13 that is inflexible and includes connections 11 and 12 at both ends; and a fixed attenuator 14 that is installed in the middle of the bypass cable 13. When one 11 of the connections is located at the position of the output unit A, the other 12 of the connections is located at the input unit D.SELECTED DRAWING: Figure 4 【課題】取り付けが簡易且つ誤りが少ない、マイクロ波多重無線装置の点検用治具を提供する。【解決手段】本発明は、周波数変換部１１３の出力部Ａとスイッチ部１０２の入力部Ｂとを接続する第１ケーブルＬ１と、ハイブリッド部１０３の出力部Ｃと増幅部１１４の入力部Ｄとを接続する第２ケーブルＬ２と、増幅部１１４の出力部Ｅとフィルタ部１１５の入力部ＦＬ３とを接続する第３ケーブルＬ３と、を備えたマイクロ波多重無線装置１０の点検時に、出力部Ａと入力部Ｄとをバイパス接続する点検用治具１であって、インフレキシブルであり、且つ両端に接続部１１、１２が設けられたバイパスケーブル１３と、バイパスケーブル１３の途中に取り付けられた固定減衰器１４とを備え、接続部の一方１１が出力部Ａの位置にあると、接続部の他方１２が入力部Ｄに位置する。【選択図】図４
