MicSig SigOFIT Optical-Fiber Isolated Probes
The MicSig SigOFIT optical-fiber isolated probes have an extremely high CMRR and isolation voltage. They help to unveil the whole truth of the signal within bandwidth.
- Present true signal: SigOFIT probes have a high common mode rejection ratio (CMRR) up to 128 dB at 100 MHz, over 100 dB at 1 GHz, for ultimate signal fidelity.
- High accuracy: Excellent amplitude-frequency characteristics, DC gain accuracy ≤1%, noise ≤0.45 mVRMS. Zero drift <0.1%, gain drift also <1%.
- Safe to test GaN.
- Wide measurement range: Use with different attenuator tips to test differential mode signals from ±0.1 V to ±5000 V, achieve full-range output and very high signal-to-noise ratio.
- Applications:
- Design of motor drive, power converter, electronic ballast.
- Design of GaN, SiC, IGBT half/full bridge devices.
- Design of inverter, UPS and switching power supply .
- Safety test for high voltage, high bandwidth applications.
- Power device evaluation.
- Current shunt measurements.
- EMI and ESD troubleshooting.
- Floating measurements.
