5G networks operate on a wider range of frequencies compared to previous generations, introducing unique challenges. To ensure these networks function properly and deliver the promised high speeds and low latency, a variety of test equipment is crucial.
A breakdown of some key categories of test equipment given below:
-
Signal Analyzers: These instruments measure the characteristics of radio signals used in 5G communication. Analyzers like the Keysight N9040B UXA can examine signal strength, purity, and modulation to identify any issues.
-
Signal Generators: Equipment like the Rohde & Schwarz SMW200A generates precise radio signals that simulate real-world 5G network behavior. This allows testing of devices and network components under controlled conditions.
-
Vector Network Analyzers (VNAs): VNAs, like the Anritsu MS4644A VectorStar, measure the performance of passive components used in 5G networks, like filters and amplifiers. VNAs ensure these components efficiently transmit and receive signals at the higher frequencies used in 5G.
-
Spectrum Analyzers: These tools, exemplified by the EXFO FTB 5GPro Spectrum Analyzer, analyze the overall radio frequency spectrum. They help identify potential interference from other sources and ensure 5G signals operate within designated frequency bands.
-
Network Master Pro: Tools like the Anritsu MT1000A Network Master Pro go beyond radio signals and test various aspects of the network infrastructure, including fiber optic connections and synchronization protocols critical for smooth 5G operation.
These are just some of the essential tools used for 5G testing. The specific equipment needed depends on the stage of development or deployment being tested. For instance, field testing during network rollout might involve portable analyzers like the Keysight N9952A FieldFox, while research and development of 5G chipsets might utilize high-performance VNAs in labs.
