Description
The SigOFIT MOIP800P (MOIP08P) fibre optic isolated probe allows the measurement of small and large voltages with a bandwidth of 800 MHz and a common mode of up to 60 kVpk. For example, a gate signal on a high-side FET or IGBT can be measured at 600 V or even 1200 V.
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, which can only test high voltage signals, the SigOFIT probe can be used with different attenuation peaks to test differential signals with voltage ranges from ±0.5V to ±5000V, 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. Automatic calibration is completed in less than 1 second and ensures accurate signal output in real time.
In addition, the MOIP800P probe has a very low input impedance of < 3 pF, a very high common mode rejection ratio of up to 110 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 128dB at 100MHz and over 108dB at 1GHz.
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 <450μVrms, and the zero drift is less than 500 μV after warm-up.
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.
