The Model FIM-72A is a portable, laboratory quality Field Strength Meter designed for rigorous field applications. Combining a calibrated half-wave dipole antenna and a highly accurate tuned voltmeter with a range of 140 dB, the FIM-72A is suitable for practically all types of RF emission measurements in the 450 MHz to 960 MHz spectrum.
The FSM1 is a lightweight, battery operated, field strength meter. This unit is ideal for making signal test measurements of all standard broadcast (VHF and UHF) and CATV channel assignments. Visual or aural carrier level, and aural verification (using built-in speaker) measurements are available.
