  • Pocket-size PIM inspector
    Patent number: 9392479
    Abstract: A method for detecting passive intermodulation (PIM) using a PIM analyzing device is provided. The PIM analyzing device transmits two signals comprising first and second signals over a signal transmission medium. The PIM analyzing device receives reflected signals associated with the transmitted signals. The PIM analyzing device determines whether the frequencies of the received signals correspond to the calculated PIM signal frequencies.
