SC11 Sensor Interface Analysis System The SC11/SI is the latest version of our comprehensive site survey equipment. It features data acquisition and pre-processing by an embedded microcomputer in the Sensor Interface for enhanced performance. The separate data acquisition card (DaqCard) used by our earlier systems is not required. The data interface to the computer is through an industry standard USB connection, which enables the system to be used with most modern laptops running Microsoft Windows. The system is designed to be flexible and adaptable to suit customer requirements. A typical system includes the Sensor Interface, a DC-10 kHz three axis magnetic field sensor, an accelerometer and a precision microphone all supplied in a rugged custom carrying case. The software suite includes three virtual instruments, an oscilloscope, a spectrum analyser and a chart recorder that display results graphically on the laptop screen. Also included are “SCplot”, a comprehensive results plotting program,  “SC11 Wizard”, which aids in setting up a single measurement, and “SC11 Survey”, which automates a complete survey.
