Product configuration
Description
The SigOFIT Gen 3 MOIP200P (MOIP02P) fibre optic isolated probe allows the measurement of low and high voltages with a bandwidth of 200 MHz and a common mode of up to 85 kVpk.
With Micsig's exclusive SigOFIT™ optical isolation technology, the SigOFIT probe is powered by a laser and delivers extremely high CMRR and isolation voltage, unlike conventional differential probes that can only test high voltage signals unlike conventional differential probes that can only test high voltage signals, the SigOFIT probe can be used with different attenuation peaks to test differential signals with voltage ranges from ±0.01V to ±20kV, achieving a full measurement range and a very high signal-to-noise ratio. Third-generation semiconductor devices such as SiC and GaN can switch high voltages in a few nanoseconds, which contain very high-energy, high-frequency harmonics. With the use of high quality coaxial attenuation tips and industry standard MCX & MMCX connectors, SigOFIT probes perfectly suppress oscillations caused by high frequency common mode noise.
Unlike previous-generation probes, the SigOFIT Gen 3 series provides calibration-free measurements and does not require auto-zero adjustment. This reduces setup time and allows engineers to begin measurements immediately while maintaining excellent accuracy and long-term stability.
In addition, the MOIP200P probe has a very low input impedance of < 3 pF, a very high common mode rejection ratio of up to 122 dB and a very accurate DC gain of 1%.

Further information

CMRR
The SigOFIT probe has a high common mode rejection ratio (CMRR) of up to 122dB at 200MHz.

GaN suitable
The Micsig SigOFIT probes were developed specifically for GaN and similar applications. To meet the high requirements, the measuring leads are short and the input capacitance is less than 3pF input capacitance.

High accuracy
The SigOFIT probe has excellent amplitude-frequency characteristics and the accuracy of the DC gain is better than 1%. The maximum noise floor within the range is <0.3mVrms, and the zero drift is less than 0.1%.

For third generation semiconductors
SiC and GaN devices can switch high voltages in a few nanoseconds and the signal can exhibit high-energy, high-frequency harmonics.
