Abstract:A 19 channel d.c. SQUID magnetometer for biomagnetic research is under construction. The system needs compactly built control and detection electronics and to facilitate the test an electronic circuit simulating the typical periodic characteristics of a SQUID was developed. In total nine steps of triangular shape were implemented with a step voltage reference generator and precision full-wave rectifier. The transfer function of the SQUID electronics and the maximum slew rate of the system could be easily measured.
