RFoF1P4MED VOLTAGE PROBE

TDS RFoF1P4MED Transducer

The RFoF1P4MED is a miniature active electro-optical wide-band sensor for induced voltage measurements. It was jointly developed with our Z43 partner organization ZMT Zurich MedTech AG (ZMT) and allows medical implant immunity testing for compatibility with magnetic resonance imaging (MRI) environments in a precise and easy manner.

All RFoF1P4MED voltage probes are fully insulated (optical power and measurement signal transfer) with minimally electrically conductive material present to ensure the lowest possible field perturbation. With the ability to measure the induced terminal voltages in active implantable medical devices (AIMD) in the frequency range from 10 MHz – 1 GHz, RFoF1P4MED fulfills all probe requirements stated in ISO/IEC TS10974 Clause 15 for Tier 3 evaluations.
