Abstract(in English) | Measurement of high frequency magnetic signals has been required from some SQUID applications, such as diagnosis of integrated circuit. We fabricated a high Tc SQUID magnetic sensor system that can treat high frequency signals. This system is composed of a SQUID, a no-modulation type flux locked loop circuit with I/O and a personal computer and a PC card. We use the FLL circuit with no-modulation to treat the high frequency signal and to simplify the circuit. This system can detect a signal from DC to 1MHz. All the sequence from tuning the SQUID to data acquisition can be done by a personal computer. This system successfully realized easy operation of SQUID measurement. |
