Many passive field strength meters have appeared in the past, typically using a 50mA analog meter movement if reasonable sensitivity was to be obtained. This circuit is similar but has the advantage ...

This simple circuit measures the strength of a radiated signal from a transmitter. It is commonly used by model airplane builders to check whether their transmitter are really transmitting the radio ...

The PI 4100’s ergonomic design makes operation simple. Field intensity meters, long a primary tool in AM field work, haven’t changed much. I have in my inventory Potomac FIM-21s, FIM-41s and even a ...

Expanding the company's portfolio of TEM cells are a range of models groomed for testing and/or calibration of field strength meters, monitors, and probes. Suitable for use in ATE systems, the cells ...

The author is senior technologist at NPR Labs in Washington. Field strength measurements are almost as old as radio itself, as engineers have endeavored to test and improve their RF transmission ...

We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the devices that ...

The HD Ranger 2 is a universal field strength meter that covers a comprehensive mix of broadcast standards around the globe. DVB-T2/C2/S2 (DVB-T/C/S also included) with MPEG-2 as well as MPEG-4 video ...
