The Nanosurf® easyPLL plus FM Detector
Technical Specifications

Advantages of the easyPLL plus Digital FM-Detector include:

High frequency resolution of 5 mHz
Low temperature coefficient
High time stability
Automatic tuning to the resonance frequency
The wide range of input and output configurations makes it very flexible and can be used together with many different systems.

Connectors and Indicators:
