Overview
The Micsig SigOFITTM optical isolated probe, MOIP Series, offers a bandwidth range from 200 MHz to 1GHz, enabling differential measurements from ±0.01 V up to ±20 kV. Built on Micsig’s exclusive SigOFITTM leading technology, MOIP Series delivers an exceptionally high CMRR, reaching up to 128 dB at 100 MHz, with an isolation voltage of up to 85 kV and an ultra-low noise floor of less than 0.3 mVrms. It reveals the complete truth of signals across its bandwidth range, serving as the ultimate referee for verifying the fidelity of signals measured by other voltage probes.
