Abstract

We have developed analog superconducting quantum interference device (SQUID) readout electronics for diverse applications. To improve their user-friendliness and flexibility, these analog circuits are embedded into a digitally-controlled system including an in-system programmable microcontroller on the electronics board and a user interface which runs on a personal computer. In this paper, we present the concept of software and hardware and discuss the achieved improvements.
