Product Overview
The Micsig SigOFIT™ 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 SigOFIT™ 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.
Present True Signal
SigOFIT probe has highest common mode rejection ratio, or CMRR, up to 128dB at 100MHz, over 100dB at 1GHz. It's the ultimate referee of signal fidelity measured by other voltage probes.
Best Probe for GaN and SiC
Third-Gen Semiconductor device like SiC and GaN can switch high voltages in a few nanoseconds, containing very high-energy high-frequency harmonics. SigOFIT probe perfectly suppress oscillation caused by high-frequency common-mode noise by employing high-quality coaxial attenuating tips and industry standard MMCX & MCX connectors, unveils real signal for every engineers.
Highest Accuracy
SigOFIT probe has excellent amplitude-frequency characteristics. DC gain accuracy ≤ 1% within ½ bandwidth, while noise ≤ 0.3mVrms. Zero drift <0.1% (works 5 mins later), gain drift also <1%.
Calibration-Free
Real-time optical power compensation ensures continuous high-fidelity waveform output in complex 24/7 measurement environments, with no manual calibration required.
Real Optical Isolation Technology
Lasers transmit signals + Power over fiber (no batteries needed, the power supply is more pure), realizes continuous test for 365 days.
