Micsig SigOFIT MOIP Series
Offers bandwidths from 100 MHz to 1 GHz with common-mode rejection ratios up to 180 dB. Differential voltage ranges from ±25V to ±6250V, depending on the attenuation tip. Ideal for power device evaluation, EMI troubleshooting, and high-voltage applications.
An optical-fiber isolated probe is a specialized sensor that uses optical fiber technology to provide electrical isolation between the probe and the measurement system. Here’s a breakdown of its use and purpose:
🔌 Main Purpose: Electrical Isolation
- The probe isolates the measurement system (like an oscilloscope or data acquisition system) from the high-voltage or noisy environment where the measurement is being taken.
- This protects sensitive equipment and users from potentially dangerous voltages or electrical surges.
📡 How It Works
- The probe converts electrical signals into optical signals, transmits them via optical fiber, and then converts them back to electrical signals at the receiving end.
- Since light signals aren’t affected by electromagnetic interference or ground loops, this ensures a clean, interference-free measurement.
🛠️ Common Applications
- High-Voltage Environments
- Power electronics testing (e.g., IGBTs, inverters, motor drives)
- HVDC transmission systems
- Medical Equipment
- Patient monitoring systems where patient safety requires isolation
- Industrial Automation
- Measuring signals in systems with multiple ground potentials
- RF and EMC Testing
- Reduces interference and ground loop issues during sensitive signal measurements
