9. We tuned the bridge current to zero before the pulse by matching an external capacitance to the capacitance of the magnetometer. During the pulse, we detected the bridge output current using the built-in current-sensing preamplifier of a Stanford Research SR850 lock-in amplifier, whose fast output was fed into a 12-bit Hewlett-Packard HP5183 transient digitizer.
