Description
Micsig SigOFIT Generation 3 MOIP350P, 350MHz, Optical-fiber Oscilloscope Isolated Probe
The third-generation Micsig SigOFIT™ optical-isolated probe, MOIP350P, offers a bandwidth of up to 350 MHz, enabling differential measurements from ±0.01 V up to ±20 kV. Built on Micsig’s exclusive SigOFIT™ leading technology, the MOIP Series delivers an exceptionally high CMRR, reaching up to DC: 180dB, 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.
- Automatic calibration: Ready for measurement upon power‑on, no manual calibration required.
- Complete electrical isolation with an isolation voltage up to 85 kV.
- Ultra‑high common‑mode rejection ratio (up to 180 dB).
- High‑speed response for accurate and reliable high‑frequency signal measurement.
- Low noise and strong immunity to electromagnetic interference.
- DC gain accuracy better than 1%.
- Fibre length: 2 m (customizable fibre length available).
- Compatible with various attenuators, supporting measurement from ±0.01 V to
- ±20 kV (differential‑mode signals; measurement voltage range is customizable).
- Design of motor drive, power converter, and 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
