Rosenberger 1800 MHz Passive Intermodulation Analyzer: Professional Diagnostic Platform for DCS Networks
Core Performance and Technical Features:
Outstanding Measurement Performance
Specifically optimized for the DCS 1800 MHz band (1710–1880 MHz), ensuring high engineering relevance and accuracy in measurement results.
Measurement sensitivity as high as ‑168 dBc, enabling accurate detection of weak intermodulation products and identification of potential interference sources.
Wide dynamic range supports 2×20W or 2×40W high‑power output, fully stimulating nonlinear device characteristics.
Efficient Fault‑Location Capability
Integrated Distance‑to‑Fault (DTF) measurement function precisely locates physical positions of PIM fault points in antenna‑feeder systems, significantly improving on‑site troubleshooting efficiency.
Supports PASS/FAIL quick‑test mode with preset industry‑standard thresholds, suitable for rapid base‑station acceptance and inspection.
Field‑Ready Design
Compact, rugged, and lightweight portable design with ergonomic features, allowing easy single‑person operation in complex environments such as base stations and towers.
Equipped with a high‑brightness sunlight‑readable display and long‑life battery to ensure all‑day outdoor operation.
Excellent dust‑resistance, shock‑resistance, and wide‑temperature operation capabilities for reliable performance in various field conditions.
Smart Data Management
Built‑in automated test procedures support one‑click PIM testing.
Real‑time data logging, result storage, and test‑report generation for traceability and analysis.
