Designed for wireless range measurements over a wide frequency band, up to 4.5 GHz. It can introduce up to 95 dB of programmable attenuation (0.25 dB step) to simulate free space signal loss over distance, measure transmitter power, monitor high-speed RF signal activity, and much more. It is suitable for most RF protocols operating within the allowed frequency bands.
The RF RANGE Shield is part of the ONDUINO family, an easy-to-use, modular, and affordable RF test solution based on open RF shields, remotely controlled via Arduino platforms over USB, with dedicated and freely downloadable firmware and application software. All ONDUINO equipment are tested and calibrated using state-of-the-art RF equipment to ensure accurate and reliable measurements.
