ISN Instrument Information
An impedance stabilization network (ISN) is a electronic device used to stabilize impedance for electromagnetic compatibility (EMC) testing. The device is placed between the equipment under test and the power supply or communication lines. It provides a consistent impedance environment while isolating unwanted noise and disturbances. This ensures accurate measurements of conducted emissions and immunity testing in compliance with EMC standards.
Common Uses
- Measuring conducted emissions in EMC compliance testing
- Isolating unwanted noise from power and signal lines
- Ensuring consistent impedance for accurate test results
- Testing electromagnetic interference (EMI) in electronic devices
