Siglent Optical Isolation Oscilloscope Probes

Ultimate Isolation for Next-Gen Power Electronics: In environments with extreme voltages and high-speed switching—like SiC and GaN power stages—standard differential probes often fall short. Siglent’s Optical Isolation Probes use fiber-optic technology to provide complete electrical isolation and industry-leading Common Mode Rejection Ratio (CMRR). Capture high-side gate signals accurately, even in the presence of massive $dV/dt$ noise.
