B&K Precision's 2650A is a compact, light weight and cost-effective spectrum analyzer for quick and precise signal investigations, especially away from the bench. At a weight of only 4 pounds (1.8 kg), the 2650A is by far the lightest full-featured spectrum analyzer available, yet it delivers performance and features comparable to a full-size bench spectrum analyzer and can operate up to 4 hours on a single battery. With its ease of use, measurement flexibility and unmatched portability, the 2650A spectrum analyzer is an indispensible tool for engineers and technicians who conduct field measurements in the 50 kHz to 3.3 GHz range.
