RF Current Monitor Probes
RF Current Monitor Probes are essential tools for measuring common-mode currents on various cables and conductors without the need to disconnect or modify the circuit under test. These probes are specifically engineered to enable non-intrusive conducted emissions measurements and comprehensive electromagnetic interference (EMI) diagnostics. By providing accurate current data, they allow engineers to identify noise sources and verify compliance with EMC standards during the product development and testing phases.
The construction of these probes ensures high reliability and ease of use when integrated with spectrum analyzers or other RF measurement equipment. The technology focuses on providing stable transfer impedance values, which range from 3dBΩ to 20dBΩ across the series, ensuring precise measurement of RF currents in complex environments. Their clamp-on design makes them ideal for testing cable harnesses, power lines, and data cables in situ without physical circuit interruption.
The series includes a wide variety of models such as the TBCP1, TBCP2, TBCP3, and TBCP4, covering a broad frequency spectrum from 30 kHz up to 1000 MHz. Aperture sizes are available in 17mm, 25mm, and 32mm diameters to accommodate a wide range of conductor thicknesses and cable bundle sizes. To ensure measurement accuracy and traceability, dedicated calibration fixtures such as the TBCP1-CAL through TBCP4-CAL are available for each probe series.
