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.

Key Features
  • 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).
Applications
  • 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
  • Current shunt measurements
  • EMI & ESD troubleshooting
  • Floating measurements

SigOFIT probe has highest common mode rejection ratio, or CMRR, up to 122dB at 200MHz, over 100dB at 1GHz. It's the ultimate referee of signal fidelity measured by other voltage probes.

Present True Signal

As the ultimate referee of signal fidelity, SigOFIT optical-fibre isolated probe delivers highest test accuracy. It has excellent amplitude-frequency characteristics, DC gain accuracy ≤1%, while noise ≤ 0.45mVrms. Zero drift<0.1% (works 5 mins later), gain drift also <1%.

Highest Accuracy

SiC & GaN device can switch high voltages in a few nanoseconds, the signal may have high-energy high-frequency harmonics.<br /> <br /> Even at the highest bandwidth, the SigOFIT probe still have nearly 100dB CMRR, perfectly suppressed the oscillation caused by high-frequency common-mode noise, no redundant components. It's the best choice for 3rd-gen semiconductor test & measurement.

Best Probe for Third-Gen Semiconductor

The test leads of SigOFIT probe are short and with coaxial cable transmission, the input capacitance is as low as 1pF minimum, very safe to test GaN.

Safe to Test GaN

Lasers transmit signals + Power over fiber (no batteries needed, the power supply is more pure), realizes continuous test for 365 days.
