Rosenberger ALPHA PIM Site Analyzer

Overview

The Rosenberger ALPHA is a portable and multifunctional broadband PIM Site Analyzer designed for precise and efficient on-site PIM testing. The single master unit features field-interchangeable, band-specific filter units with a consistent form factor, allowing users to swap filters without requiring recalibration. This future-proof plug-and-play design covers frequencies from 700 to 2700 MHz.
