The circuit was designed to measure the electric field strength in radio frequency band where it can be applied during the modulation of AM and FM signals in the VHF range. Field Strength – the ...

Priced at only $80, the portable RF Meter is a low-cost signal-strength measurement tool for designers of RF radio systems. Two models are available to detect signals ...

You can easily check your Wi-Fi signal's strength, right down to the exact dBm levels, on a Mac or PC computer. Signal strength is measured in decibel milliwatts (dBm ...

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 ...
