Optical Fibre Isolated Oscilloscope Probes

Optical fibre isolated oscilloscope probes transmit the measured signal to the oscilloscope through a fibre link, providing electrical isolation between the probe head and the instrument. They are useful for floating measurements and circuits with high common-mode voltage or fast switching edges, where probe isolation and common-mode rejection are important.

Applications in Power Electronics and EMI Testing

Use optical fibre isolated probes to measure signals in motor drives, power converters, inverters, UPS systems and switching power supplies. They are also used for evaluating IGBT, SiC and GaN power devices, measuring current shunts, and investigating EMI and ESD issues. In fast-switching circuits, high common-mode rejection can help distinguish the differential signal from common-mode interference.

Choosing an Optical Fibre Probe

Compare bandwidth and rise time with the signals you need to measure. Also check the differential input range and probe tip, common-mode voltage rating, common-mode rejection across the frequency range, input capacitance, noise and fibre length. Telonic’s range includes optical fibre solutions from Micsig, Siglent, Rohde & Schwarz and Rigol. Check each model’s specifications and accessories to confirm it suits your oscilloscope and application.
