RF Measurement Accessories
RF Measurement Accessories
RF measurement accessories are passive and active supporting components used alongside spectrum analyzers, signal generators, power meters, and vector network analyzers in RF and microwave test setups. This category includes attenuators, EMC near-field probes, power elements, terminations, and directional couplers. Engineers in telecommunications, aerospace and defense, electronics manufacturing, and R&D laboratories rely on these accessories to accurately characterize signals, manage power levels, and ensure compliance with regulatory standards.
Attenuators such as those from Bird Electronics reduce signal levels without distorting the waveform, protecting sensitive analyzer inputs and extending the usable dynamic range of test systems. EMC probes from Beehive Electronics enable near-field electromagnetic compatibility testing, allowing engineers to localize emission sources on PCBs and assemblies during pre-compliance and formal EMC testing campaigns.
Typical Applications
- Attenuating RF signals to protect spectrum analyzer and receiver inputs during high-power transmitter testing
- Near-field scanning of PCBs to identify and localize radiated emission sources for EMC compliance
- Measuring RF power levels with calibrated plug-in power elements in Bird-style directional wattmeters
- RF and microwave system characterization in aerospace, defense, and wireless communications labs
- Pre-compliance and regulatory EMC testing in electronics manufacturing and product development
