MESA Handheld Spectrum Analyzer

Portable Spectrum Analyzer

The MESA® is a portable, handheld RF receiver that detects known, unknown, illegal, disruptive, or interfering transmissions. MESA® has the portability and operational features not found on  other spectrum analyzers. It provides tools, specifications and design features for locating unknown signals throughout a wide frequency range up to 6 GHz (12 GHz with the Down Converter antenna).  MESA® has a new Patented SmartBars™ operational mode that displays signal activity in a bar graph.

Efficiency: MESA® is easy to set up and puts sweep data at your fingertips with user friendly navigation. Auto antenna recognition makes changing antennas a snap.

Usability: Full touchscreen control provides quick access to Spectrum, WiFi, Bluetooth®, Mobile Bands, and SmartBars™ modes.

Portability: Portable, handheld unit can sweep target areas using a full selection of fixed, bracket mounted, and hand held antennas/probes.
