FIM-71 is a portable, laboratory quality Field Strength Meter designed for rigorous field applications. The operator can switch select wide or narrow bandwidth, peak or average value of TV or pulse modulated signals, AM or FM demodulation, and a meter dynamic range of either 20 dB or 60 dB. A dc analog output voltage, proportional to the meter indication, is provided for driving a chart recorder. A leveled output from the calibrating oscillator is available for measuring cable insertion loss, filter response, amplifier gain, and other signal ratio measurements. The tuned voltmeter is a single conversion, super-heterodyne receiver with carefully tailored sensitivity, gain, and linearity characteristics. Field strength data are with ANT-71 Antenna.
TYPE Tunable half-wave dipole with continuously adjustable telescoping elements.
