STL Systemtechnik
The digital SQUID electronics control system DSE32 is designed to allow for multi-channel SQUID data collection. The electronics in combination with the GradMag® software offers a powerful and easy SQUID control including auto calibration for both high-Tc and low-Tc SQUIDs. The combination of a large 5 MHz bandwidth, an extraordinary 20 million Phi0/sec slew rate, a basically 32 bit dynamic range, and a high >140 dB linearity grants a wide spectrum of system applications especially in unshielded environment. STL\'s bidirectional low-noise fiber-optic interface (BiFOC) with a data rate of 2 MBytes/s offers sampling rates of more than 100 kHz with 3 channels simultaneously running. In special cases like logarithmic sampling a maximum sampling rate of 10 MHz can be used. The low power consumption results in a low noise contribution and long lifetime battery operation. Due to the phase synchronized fiber-optic network a multi-channel system can be organized with up to several hundred simultaneously triggered channels. The electronics may be run by a notebook using the unique fibre-optic PCMCIA card under various operating systems.
