Lock-in amplifier DME Danish Micro Engineering A/S

Our fully digital 20 MHz Lock-In amplifier is an optimal extension to our AFM systems. It is specially optimized for electrical AFM measurements and provides nth harmonic detection and an integrated feedback loop for kelvin probe force (KFPM) measurements and many other features. It can of course also be used for other applications, independent of an AFM system.

This device also acts as a digital storage oscilloscope. It is controlled via a small java front end running on a PC. The connection between the amplifier and the front end is made via ethernet which results in extremely fast update rates for the displayed oscilloscope data. The front end runs on all standard operating systems where a Java runtime environment can be installed (e.g. Windows / MAC / Linux).
