The OPL6000 Series Laser-Powered Optically Isolated Probes are fiber-optic isolated voltage probes with ultra-high common mode rejection ratio (CMRR). The CMRR of traditional differential probes drops rapidly in the high-frequency band, making it extremely difficult to accurately measure small voltage signal waveforms under high common mode interference voltages (e.g., measuring the drive voltage of the upper tube in a half-bridge circuit). The OPL6000 adopts a high-performance laser fiber-optic signal transmission system, thus achieving ultra-high CMRR throughout the entire operating bandwidth, which can help customers complete such challenging measurements at a very low cost.
