The electrically adjustable attenuator is based on the Faraday rotation effect, by using all solid-state magneto-optical technology, no mechanical moving parts, having ultra-fast response speed (up to 0.3ms), and more reliable performance, longer service life.
Features:
- No mechanical moving parts, high reliability
- Switch fast
- State lock stable
- Low power consumption
Applications:
- Sensing system
- System monitoring
- Test measurement
