  • Power Line Meter

    Alpha Lab, Inc.

    The Line EMI Meter measures electromagnetic interference in a single-phase AC power line. It plugs into a wall outlet (mains socket) and requires no battery. It immediately displays total line noise in millivolts (range 1999 mV, resolution 1 mV) in the frequency range 10 KHz 10 MHz (the frequency limits at which sensitivity is of the maximum sensitivity). A speaker plays the sound of the EMI, amplitude demodulated, in order to identify the EMI source (such as an AM or shortwave radio station vs. a motor vs. an electric arc).

  • CAT-5 Video Receivers

    Analog Devices Inc.

    Analog Devices high speed, differential CAT-5 video receivers and equalizers compensate for the transmission losses of UTP and coaxial cables up to 300 meters in length. Various gain stages are summed together to best approximate the inverse frequency response of the cable. Logic circuitry controls the gain functions of the individual stages so that the lowest noise can be achieved at short-to-medium cable lengths. Our video receivers provide excellent common-mode rejection that enables the use of low cost, unshielded twisted pair cables in noisy environments.
