Plane Wave Test System
The PWC2000 planar wave test system is a dedicated measurement instrument designed for the R&D, quality assurance, production, and OTA compliance testing of 5G massive MIMO base stations. Built on an integrated architecture that combines a phase‑shifting attenuator network with a probe array, it can generate high‑quality planar waves within a specified quiet zone, enabling far‑field‑like measurements at near‑field distances without the need for near‑to‑far field transformation algorithms, thereby significantly reducing both test space requirements and test time.
The device integrates a broadband antenna array, high‑precision phase‑shifter/attenuator modules, a low‑noise amplification chain, a high‑speed switch matrix, and a timing‑synchronization system. It supports remote control via Ethernet, batch parameter configuration, self‑calibration, and status monitoring, thereby meeting the automated RF‑parameter testing requirements of base stations with multiple ports.
• 5G base station OTA testing: equivalent isotropically radiated power (EIRP/TRP), modulation quality (EVM), adjacent-channel leakage ratio (ACLR), spectral emission mask (SEM), receiver sensitivity, dynamic range, and blocking and intermodulation.
• Antenna array characterization: gain, radiation pattern, and polarization isolation; efficiency, port isolation, and voltage standing wave ratio (VSWR); near-field plane-wave synthesis and quiet-zone verification.
• Compact size: Offers a significant cost advantage within the sub‑8 GHz band, with a footprint up to four times smaller than that of far‑field test systems.
• High-quality quiet zone: amplitude imbalance: ±0.5 dB (3.5 GHz), phase imbalance: ±4° (3.5 GHz).
• Wideband High Power: Full‑band coverage from 2 to 8 GHz, with an average power of ≥30 dBm in ANT continuous wave/thermal switching mode.
• High-precision control: 0–25 dB attenuation (in 0.1 dB steps), 360° phase shifting (in 1° steps), and channel alignment calibration.
• High Isolation, Low Loss: Multi-channel design with high isolation, delivering excellent insertion loss and VSWR.
• High reliability: Rigorously validated through stringent reliability tests, including vibration, shock, thermal cycling, and aging.
• User-friendly software: Ethernet communication, configuration import/export, IP address display, and remote command control.
• Compact design: meets installation space constraints, features no sharp edges, standardized connectors, and a foolproof power‑supply design.
