Key Features
Overview
The Micsig SigOFIT optical-fibre isolated probe is a cutting-edge measurement tool for professional electronic engineers. Utilising exclusive SigOFIT™ technology, this probe offers unparalleled signal fidelity and isolation performance. With a bandwidth of DC-1GHz and a common mode voltage of 85kVpk, it unveils the true nature of signals in high-voltage, high-frequency applications.
Boasting an impressive CMRR of up to 180dB, the SigOFIT probe suppresses common-mode noise, making it ideal for testing third-generation semiconductors like SiC and GaN devices. Its low input capacitance of 1pF minimum ensures safe testing of sensitive components. The probe's wide measurement range, from ±0.01V to ±6250V, coupled with its high accuracy (DC gain accuracy ≤1%), makes it versatile for various applications, including motor drive design, power converter testing, and EMI troubleshooting.
Engineered for efficiency, the SigOFIT probe features rapid response times and AutoZero functionality, completing in less than a second. Its optical isolation technology, powered by fibre, enables continuous testing for up to 365 days without battery concerns. This probe is an essential tool for engineers seeking precise, reliable measurements in challenging electronic environments.

Frequently Asked Questions
Have a Question?
-
What maintenance is required for the optical fibre cable and how robust is it for laboratory use?
The fibre cable requires careful handling with minimum bend radius of 8cm. It's designed for laboratory use but should be protected from sharp bends, crushing, or excessive tension to maintain signal integrity.
-
Can the SigOFIT probe measure both AC and DC components simultaneously in power converter circuits?
Yes, the probe has DC coupling capability with excellent low-frequency response down to DC, enabling measurement of both switching transients and DC bias levels in power electronic circuits.
-
What safety considerations apply when using the SigOFIT probe in high-voltage environments?
Whilst the probe provides galvanic isolation, proper safety procedures must be followed including appropriate PPE, isolated test fixtures, and adherence to local electrical safety regulations when working with high voltages.
-
How does optical isolation compare to more expensive competitor solutions like Tektronix IsoVu probes?
The SigOFIT offers comparable isolation performance and bandwidth at significantly lower cost, with the advantage of universal oscilloscope compatibility versus proprietary scope requirements of premium alternatives.
-
Is the SigOFIT probe compatible with my existing oscilloscope?
The probe works with any oscilloscope having standard BNC input connectors and 50Ω input impedance, including models from Tektronix, Keysight, Rohde & Schwarz, LeCroy, and Rigol without requiring special software.
-
What attenuator tips are available, and how do I select the correct one?
Attenuator tips range from 10X to 10000X ratios. Select based on your expected signal amplitude to achieve full-scale deflection on your oscilloscope for maximum measurement resolution and signal-to-noise ratio.
-
How does the auto-calibration feature work and how often is calibration required?
The probe performs automatic zero calibration in under one second by pressing the calibration button. No disconnection is required and calibration should be performed when changing measurement ranges or after extended operation.
-
Which SigOFIT model should I choose for my application bandwidth requirements?
Select based on your signal frequencies: MOIP100P (100MHz) for basic power supplies, MOIP500P (500MHz) for most SiC applications, or MOIP1000P (1GHz) for high-frequency GaN circuits and advanced power converters.
-
Can the SigOFIT probe safely measure gate signals on high-side GaN and SiC MOSFETs?
Yes, the probe's complete galvanic isolation and ultra-short test leads with minimal parasitic capacitance make it ideal for measuring fast-switching wide bandgap semiconductors without affecting circuit operation or causing device damage.
-
What makes the SigOFIT probe better than traditional differential probes for power electronics testing?
The SigOFIT probe uses optical isolation technology providing 180dB CMRR compared to typical 80dB from differential probes, eliminating common-mode interference that corrupts measurements in high-voltage switching circuits.
