Description: McMartin TBM-3500B FM Monaral Modulation Monitor Pro Broadcast Audio Working This works. Comes from a pile of equipment out of a closed radio station. Power cord included. Shows signs of wear. Sold as is . DIRECT READING AM & FM SIN MODULAR PLUG -IN CONSTRUCTION OPTIONAL PLUG -IN LOW LEVEL INPUT INTERNAL CALIBRATION CARRIER FAILURE ALARM REMOTE METERING AVAILABLE The McMartin TBM -3500B monitors the modulation of main -channel FM broadcast stations, and when used with a) the TBM- 2200A, all parameters of stereophonic transmission; and/or b) the TBM- 2000B, all parameters of SCA multiplex operation. The TBM -3500B permits metering of total positive and negative modulation and measurement of FM and AM signal -to -noise ratios as low as - 70 dB. A peak flasher independent of meter switching indicates the highest positive or negative peak encountered. Threshold is adjustable from 50% to 120 %.The meter functions as a semi -peak reading voltmeter for modulation. When used to read AM or FM noise the meter is damped to improve readability in the presence of noise. Meter positions are provided to read the inherent internal noise (typically - 75 dB below 100% modulation) of the monitor and internal calibration. When reading AM, FM or internal noise 75 microsecond de- emphasis is automatically inserted into the measuring circuit.
