Learn what to consider when buying a lock-in

Lock-in amplifiers are important tools for test engineers and material researchers because of their unique ability to precisely measure signals that are otherwise too small to detect amidst noise and other interfering signals.

Researching and evaluating lock-in types can be confusing. This paper aims to simplify the selection and buying process.

We’ll examine:

• The benefits and standard functions of a lock-in amplifier
• The different types of lock-in amplifiers
• Key choice considerations 
• Steps involved in evaluating and qualifying a lock-in amplifier
• How to overcome the learning curve when using lock-in amplifiers
• Examples where a lock-in amplifier alone may not be the complete solution

Lock-in amplifiers improve measurement quality by enhancing the signal-to-noise ratio and enabling phase-sensitive detection. Find the right one for your research.
