Transmitter Power Monitor
TPM Series
} Low Cost in-situ power measurement solution designed for operation inside the transmitter or after the combiner.
} In-line calibration capability allows for greater accuracy in a single application (with an accurate power reference).
} Integrated non-directional coupler allows for spectral analysis of the signal in minimal space requirements.
} Accurately measures true average power for digitally modulated systems.
} +/- 5% of reading accuracy for both forward and reected power (10:1 ratio for forward to reected power)
} 7/8”, 1 5/8”, and 3 1/8”, 50 ohm lines available for FM, VHF, and UHF broadcast frequencies.
} DB9 output provides a linear DC voltage output from 0 to 4 volts allowing for a wide variety of interface options.
