Description

The SigOFIT Gen 3 MOIP200P fiber-optic-isolated probe enables the measurement of low and high voltages with a bandwidth of 200 MHz and a common-mode level of up to 85 kVpk.

Thanks to Micsig’s exclusive SigOFIT™ optical isolation technology, the SigOFIT probe is laser-driven and delivers extremely high common-mode rejection ratio (CMRR) and isolation voltage. Unlike conventional differential probes, which can measure only high-voltage signals, the SigOFIT probe enables the measurement of differential signals in voltage ranges from ±0.01 V to ±20 kV. This achieves a full measurement range and a very high signal-to-noise ratio. Third-generation semiconductor devices, such as SiC and GaN, are capable of switching high voltages in a matter of nanoseconds. This generates high-energy, high-frequency harmonics. The use of high-quality coaxial attenuation tips and industry-standard MCX and MMCX connectors perfectly suppresses the oscillations in the SigOFIT probes caused by high-frequency common-mode noise.

Unlike previous-generation probes, the SigOFIT Gen 3 series enables calibration-free measurements and requires no automatic 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 features a very low input impedance of < 3 pF, a very high common-mode rejection ratio of up to 122 dB, and a highly accurate DC gain of 1%.

The combination of probe and attenuation tip determines the probe's technical specifications. To find the right tip for your intended application, it is important to correctly determine the key parameters: differential voltage range, maximum input voltage, and input resistance. If you are unsure, we recommend contacting our technical support team.

Present True Signal

SigOFIT probe has highest common mode rejection ratio, or CMRR, up to 128dB at 100MHz, over 100dB at 1GHz. It's the ultimate referee of signal fidelity measured by other voltage probes.

Highest Accuracy

The SigOFIT optical-fiber isolated probe delivers highest test accuracy. It has excellent amplitude-frequency characteristics, DC gain accuracy ≤1 %, while noise ≤ 0.45 mVrms. Zero drift <0.1 % (works 5 mins later), gain drift also <1 %.

Best Probe for Third-Gen Semiconductor

SiC & GaN device can switch high voltages in a few nanoseconds, the signal may have high-energy high-frequency harmonics. Even at the highest bandwidth, the SigOFIT probe still have nearly 100dB CMRR, perfectly suppressed the oscillation caused by high-frequency common-mode noise, no redundant components. It's the best choice for 3rd-gen semiconductor test & measurement.

Safe to Test GaN

The test leads of SigOFIT probe are short and with coaxial cable transmission, has less than 2.5pF input capacitance, very safe to test GaN.

When the working parameters of the device are already in the critical state of explosive, there will be nearly 2.5pF more capacitance added when connected to the DUT, safety hence is not guaranteed.

Wide Measurement Range

Unlike traditional differential probes can only test high-voltage signals, SigOFIT probe can be used with different attenuator tips to test differential mode signals from ±0.1 V to ±8,000 V, achieve full-range output and very high signal-to-noise ratio.
