System Core: Targeted Band Design and Professional Measurement Capabilities
Core Performance and Technical Features:
Precision Band-Targeted Optimization
The frequency range precisely covers 1710‑1880 MHz (DCS 1800) and extends to related bands such as 1930‑1990 MHz (PCS 1900). Hardware and algorithms are deeply optimized for the characteristics of these bands, ensuring highly relevant engineering measurement results.
Employs 2×40W high‑power excitation signals to fully activate the nonlinear characteristics of antenna‑feeder systems, guaranteeing rigorous and realistic testing.
Exceptional Measurement Sensitivity and Dynamic Range
Measurement sensitivity as high as ‑168 dBc enables accurate detection of weak intermodulation products caused by minor connection defects or slight contamination.
Dynamic range >110 dB ensures clear identification of tiny interference signals even in the presence of strong primary signals.
Intelligent Fault Location and Diagnostics
Integrated high‑precision Distance‑to‑Fault (DTF) measurement function with location accuracy up to ±0.5 meters, allowing rapid and precise physical location of PIM fault points (e.g., specific jumpers, connectors, or antenna ports) in the antenna‑feeder system.
Features real‑time PIM trend monitoring and event marking to help field engineers analyze dynamic changes in interference.
Rugged Field‑Ergonomic Design
Ergonomic portable design with high‑strength protective housing and a high‑brightness sunlight‑readable touchscreen, suitable for complex environments such as cell‑tower tops and indoor distributed systems.
Built‑in large‑capacity lithium battery and intelligent power management support extended continuous field operation.
Typical Application Scenarios:
DCS/PCS Base Station Antenna‑Feeder System Acceptance and Inspection: Final acceptance testing for new or expanded base stations, and regular preventive maintenance testing of existing sites.
Precision Troubleshooting of High‑Interference Cells: Rapidly locate and resolve the root causes of intermodulation interference that degrade network uplink sensitivity.
Incoming Quality Inspection of Passive Components: Screening and verification of PIM performance for critical passive devices such as antennas, filters, combiners, and feeders.
Quality Assurance for Indoor Distributed Antenna Systems (DAS): Ensuring the intermodulation performance of indoor coverage systems in large venues, transportation hubs, etc., meets design specifications.
