Overview
The Micsig MOIP200P is a fiber-optically isolated oscilloscope probe designed for differential and floating voltage measurements in power electronics and semiconductor testing. It provides 200MHz bandwidth with 1.75ns rise time and exceptional common-mode rejection, delivering a complete galvanic isolation solution for high-voltage and sensitive measurement environments.

Key Features

• 200MHz bandwidth: 1.75ns rise time for reliable capture of switching transients.
• High CMRR: 180dB DC common-mode rejection, 122dB at 200MHz.
• 85kV galvanic isolation: 85kVpk isolation rating for high-potential testing.
• Low noise and high accuracy: <0.3mVrms noise, 1% DC accuracy, 0.1% offset drift reduction.
• Modular attenuators: Measurement range 10mV to 20kV with interchangeable tips and dual 0dB/20dB ranges.
• Low input capacitance: 1pF with short coaxial leads to minimize circuit loading.
• Continuous optical calibration: Optical power compensation and automatic calibration for stable long-term measurements.
• Standard interface: BNC output, 2 m fiber optic cable, 12V DC supply.

Applications

• SMPS and DC-DC converter validation
• Motor drive and inverter waveform analysis
• IGBT and wide-bandgap semiconductor testing
• High-voltage insulation and medium-voltage system tests
• EMC/ESD diagnostics and signal integrity verification
