MOIP200P SigOFIT Fiber Isolated Oscilloscope Probe

The MOIP200P is an entry-level high-performance fiber isolated oscilloscope probe from Micsig's SigOFIT optical probe family, optimized for differential signal testing and floating voltage measurement in general power electronics design and validation applications. Built on proven SigOFIT core technology, this Micsig 200MHz probe delivers 200MHz bandwidth with 1.75ns rise time, enabling accurate capture of standard switching transients in wide bandgap semiconductor test and power device characterization workflows. Featuring exceptional common mode interference rejection with 180dB DC common mode rejection and maintaining 122dB CMRR at 200MHz, the MOIP200P provides a complete galvanic isolation solution with effective ringing suppression for switch-mode power supply and motor drive designs. With below 0.3mVrms noise floor and 1 percent DC accuracy, this probe delivers reliable ultra low noise detection performance with 0.1 percent offset drift reduction for dependable long duration measurement in extended testing environments. The 85kVpk isolation rating delivers robust high potential isolation for high voltage insulation test and industrial medium-voltage power system applications. The 1pF input capacitance with short coaxial test leads minimizes circuit loading effects, making the probe suitable for safe IGBT circuit testing and semiconductor device evaluation without adversely impacting the device under test. Flexible measurement range from 10mV minimum voltage to 20kV maximum voltage is achieved through modular attenuator design with interchangeable attenuator tips, covering everything from low-level signal analysis to high-voltage power measurements. The dual attenuation range capability between 0dB and 20dB further optimizes signal-to-noise ratio within each measurement range. Integrated continuous optical calibration ensures consistent high-fidelity waveform output in demanding long-term measurement environments, paired with automatic calibration probe functionality for immediate measurement readiness upon power-up. With 2 meter fiber optic cable, 12 volt DC power, and standard BNC interface with BNC output connector, the MOIP200P integrates seamlessly into standard test benches for motor drive development, DC-DC converter testing, SMPS design validation, inverter waveform analysis, uninterruptible power supply test, semiconductor device evaluation, precision current measurement, electromagnetic compatibility test, and electrostatic discharge analysis applications. Solid electromagnetic resistance and high frequency disturbance rejection make this probe a cost-effective reference standard for signal integrity verification and characterizing power semiconductor devices at 200MHz bandwidth.
