BK Accuracy's 2650A series handheld spectrum analyzers are compact, light weight, and cost-efficient spectrum analyzers for fast and exact signal examinations, especially away from the bench. At a weight of just 1.8 kg (4 pounds), the 2650A series are without a doubt the lightest full-featured spectrum analyzer readily available, yet they deliver performance and functions similar to full-size bench spectrum analyzers and can operate as much as 4 hours on a single battery.
