The 2650A series of compact, light weight and cost-effective spectrum analyzers are for quick and precise signal investigations, especially away from the bench. At a weight of only 4 pounds (1.8 kg), these instruments are by far the lightest full-featured spectrum analyzers available, yet they deliver performance and features comparable to a full-size bench spectrum analyzers and can operate up to 4 hours on a single battery. With their ease of use, measurement flexibility and unmatched portability, the 2650A series are an indispensible tool for engineers and technicians who conduct field measurements in the 50 kHz to 8.5 GHz range.
