Lock-in amplifiers

The lock-in amplifiers in our portfolio provide high performance at a reasonable cost. They are used to detect and measure very small AC signals all the way down to a few nanovolts. Accurate measurements may be performed even when the small signal is obscured by noise sources many thousands of times larger.
