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 handheld 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.

Marker measurement | NORM：displays frequency (8 digits max) and level (4 digits max) at marker point. DELTA：displays frequency difference and level difference between two markers. | |
Peak search | NORM: searches peak point within 10div (full freq. range). This mode also supports NEXT peak ( up to 10). ZONE: searches peak point within a zone designated by center and width | |
Calculations | NORM, MAX HOLD, MIN HOLD, AVERAGE, OVER WRITE MAX/MIN HOLD: 2 to 1024 AVERAGE: 2 to 256 | |
Measurements | Measure Channel power, Adjacent channel leakage power, Occupied frequency bandwidth, Electric field strength (requires antenna), Magnetic field strength (requires magnetic field probe). | |
