MOIP350P SigOFIT Gen3 Optical Fiber Isolated Probe

The MOIP350P is a professional optical fiber isolated probe from Micsig's third-generation SigOFIT product series, designed for precision differential voltage testing and floating circuit measurement in mid-bandwidth power electronics applications. Built on SigOFIT exclusive technology, this Micsig differential probe delivers 350MHz bandwidth with 1ns maximum rise time, enabling accurate capture of medium-speed switching transients in GaN semiconductor testing and SiC power device test scenarios. Featuring ultra high CMRR with 180dB DC CMRR and maintaining 118dB CMRR at 350MHz, the MOIP350P provides full electrical isolation with effective common mode oscillation suppression for power converter and motor drive designs. With less than 0.3mVrms noise floor and 1 percent gain accuracy, this probe delivers high-precision low noise floor measurement performance with 0.1 percent zero drift control for dependable 24/7 measurement stability in continuous testing environments. The 85kVpk common mode voltage rating delivers robust high voltage isolation for high voltage safety test and industrial high-voltage power system applications. The 1pF minimum input capacitance with short coaxial test leads minimizes circuit loading effects, making the probe suitable for safe IGBT half bridge testing and power component evaluation without adversely affecting the device under test. Broad measurement versatility from 0.01V low voltage measurement to 20kV peak measurement voltage is achieved through interchangeable attenuators with replaceable attenuator tips, covering everything from low-level signal analysis to ultra-high-voltage power measurements. The gain range switching capability between 0dB and 20dB further optimizes signal-to-noise ratio within each measurement range. Integrated real time power compensation ensures continuous high-fidelity waveform output in demanding round-the-clock measurement environments, paired with power on auto calibration for immediate measurement readiness as soon as the probe is powered up. With 2m standard fiber length, 12V DC power input, and universal BNC connector with BNC output interface, the MOIP350P integrates smoothly into existing test setups for motor controller design, power converter testing, electronic ballast design, inverter performance test, UPS system testing, power component evaluation, current shunt testing, EMI problem troubleshooting, and ESD issue diagnosis applications. Superior EMI immunity improvement and high frequency noise rejection make this probe an excellent reference standard for signal truth verification and characterizing wide-bandgap semiconductor devices at 350MHz bandwidth.
