SC11 Compact Analysis System
The SC11/Compact is our popular site survey equipment. It features data acquisition and pre-processing by an embedded microcomputer in the magnetic field sensor, 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.
Spicer Consulting has built a world-wide reputation in magnetic field cancelling for electron microscopes and similar instruments. Today, working with equipment manufacturers and users alike, the company is recognised as an industry expert in maximising the performance of electron microscopes, electron beam lithography systems, CD-SEM and focused ion beam tools. Spicer Consulting magnetic field cancelling systems protect sensitive equipment in the world's leading laboratories, universities and semiconductor manufacturing plants, as well as in the test facilities of electron and ion beam equipment manufacturers. Its magnetic field, vibration and acoustic analysis systems have been adopted as standard equipment for the conduct of site surveys by leading equipment manufacturers.

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. The core system includes the Sensor Interface, Software and a custom carrying case. And a typical system also includes a DC-13 kHz three axis magnetic field sensor, an accelerometer and a precision microphone. 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.
Magnetic Field Sensor
The SC11/Compact three axis magnetic field sensor is derived from sensors used in the Spicer Consulting range of magnetic field cancelling systems. It contains a three-axis inductive pick up coil (X, Y, & Z) connected to precision analog integrators, to measure AC magnetic fields. The measurement range is 80 mG pk-pk with a bandwidth of 1 Hz to 20 kHz and the total noise limit in the band is 3μG RMS. Post-processing in the laptop computer enables the low frequency limit to be extended to 0.1Hz with minor increase in the 1/f noise limit. The measurement accuracy is ± 1%. .
The accelerometer supplied is a Wilcoxon Research model 731A, with a measurement range of 200 mg's pk-pk and a bandwidth of 0.1 Hz to 500 Hz. It is suitable for the measurement of extremely low level vibrations. Its noise limit is 0.03μg/√Hz at 2Hz. The accelerometer measures along one independent axis. It can be rotated to measure three orthogonal axes (one at a time) while standing on a horizontal plane.
Digital Sound Level Meter
The sound level meter supplied is an Extech 407730 for general purpose sound measurements. It can measure from 40 to 130 dB on its internal meter. The sound level meter connects to the Magnetic Field Sensor Aux input through a coax cable.
Flux Gate Magnetometer
The optional flux gate magnetometer is a μMAG-01N from MEDA. It measures one axis magnetic fields from DC to 400 Hz, with a maximum range of ±2000 mG and a meter resolution of 0.01 mG on the most sensitive 20 mG range. The Meda meter connects to the Magnetic Field Sensor Aux input through a coax cable.
