Eagle-40 is a compact, field-convenient mmWave receiver engineered for high RF performance and fast sampling speed in CW testing and RF environment scanning at 24-40 GHz frequencies. The device features sensitivity of -115 dBm with ±1.5 dB amplitude accuracy and operates at 550 samples per second to conform to 40-lambda lee criteria. It includes an optional car odometer interface that synchronises measurements with vehicle odometer for equidistant sampling and highest test integrity. Compatible with WalkView Windows software, Eagle-40 automatically maps results on Google Maps with GPS tagging and exports data to multiple radio planning tools including Atoll, ASSET, Planet, and Mapinfo. Rugged form factor enables rapid outdoor mmWave deployment.
