3 channel Electronics with Touch Panel

The JSQ SQUID Electronics is used to generate the pumping radio frequency for SQUID operation, with the required adjustments of rf frequency and amplitude for working point adjustment. Furthermore, the electronics serves as preamplifier and demodulator of the rf response of the SQUID. The SQUID is kept at a well-defined flux state (working point). This operating principle ensures a linear transfer function. It allows a dynamic range from a few 10-5 to about 103 magnetic flux quanta with excellent linearity.
