Micsig MOIP1000P SigOFIT probe head

Description

The Micsig SigOFIT MOIP1000P offers a bandwidth of 1 GHz and an outstanding common mode rejection ratio (CMRR) of 108 dB at 1 GHz, enabling highly accurate differential measurements in demanding high-voltage and high-frequency applications.

The Micsig SigOFIT Gen 3 series represents the latest generation of optically isolated probes, designed to deliver exceptional measurement accuracy, safety, and reliability. Utilizing Micsig's innovative SigOFIT™ technology and laser-powered optical transmission, these probes provide complete galvanic isolation between the oscilloscope and the device under test, significantly reducing interference from common-mode voltages while ensuring uninterrupted high-precision measurements.

With a CMRR of up to 180 dB at DC and 108 dB at 1 GHz, the SigOFIT Gen 3 series accurately captures differential signals even in the presence of strong common-mode voltages. This makes the probes ideally suited for applications involving power electronics, motor drives, inverters, DC/DC converters, electronic ballasts, and advanced GaN and SiC semiconductor devices.

Key Features and Benefits

Optical Isolation Technology
SigOFIT probes utilize fiber-optic transmission to provide complete electrical isolation between the measurement system and the test circuit. This enhances measurement safety and minimizes the influence of noise and common-mode interference.

Calibration-Free Measurements
Unlike conventional high-voltage differential probes, the SigOFIT Gen 3 series eliminates the need for routine calibration and auto-zero procedures. Users can start measurements immediately, reducing setup time and improving productivity.

Outstanding Temperature Stability
Advanced optical architecture ensures excellent temperature stability with virtually no temperature drift, maintaining measurement accuracy during extended testing sessions and changing environmental conditions.

High Measurement Accuracy
With a gain accuracy of 1% at DC and noise suppression below 0.3 mV RMS, the SigOFIT series enables reliable analysis of even the smallest signal variations.

Flexible Measurement Range
The SigOFIT platform supports a wide range of interchangeable attenuators, enabling differential-mode measurements from ±0.01 V up to ±20 kV. Customized measurement voltage ranges are also available for specialized applications. For low-voltage applications, the probe can also be used without an attenuation tip by connecting an SMA adapter directly to the probe. In this configuration, the probe utilizes an internal attenuation ratio of 2:1, making it suitable for accurate small-signal measurements while maintaining the benefits of optical isolation technology.

Versatile Applications
Ideal for power electronics development, inverter testing, high-voltage safety verification, semiconductor characterization, and advanced R&D applications where high bandwidth, high isolation, and superior signal integrity are essential.

Compact and Robust Design
Designed for both laboratory and industrial environments, the SigOFIT probes combine advanced measurement technology with a compact and durable construction.

Customizable Fiber Length
Each probe is supplied with a standard 2-meter fiber optic cable, while customized fiber lengths are available to accommodate specific laboratory layouts and testing requirements.

The SigOFIT Gen 3 series is engineered to meet the highest safety and performance standards, providing engineers with a reliable solution for precise differential measurements in challenging high-voltage and high-frequency environments.
