Very low noise data acquisition. SMART processing - superior rejection of power line, sferic, VLF and telluric interference. Integrated spectrum analyzer and oscilloscope functionality. Compatible with Zonge, Geonics, Iris and other transmitter systems. Automated functions for synchronization, 3-component borehole TEM and calibration. Windows 98 operating system.

The SMARTem system was developed by ElectroMagnetic Imaging Technology (Perth, Western Australia) during 1995. Since then it has evolved to become the most powerful system of its kind on the market. It is a platform for the routine acquisition of surface, borehole and underground TEM data in fixed and moving loop formats. SMARTem can assist in the research and development of new TEM acquisition and processing techniques and can be configured quickly by the manufacturer to proprietary specifications. It includes:

QWERTY keypad Large hard disk drive Backlit VGA LCD screen (fully functional in bright sunlight) Printer and serial ports and external keyboard and screen connectors

The SMARTem system includes a remote synchronized transmitter controller. SMARTem achieves high signal-to-noise ratios by virtue of rapid sampling of receiver voltages and novel digital signal processing techniques implemented in its control software. Unique techniques for the treatment of power transmission line, atmospheric, VLF transmitter and other interference have been developed to significantly attenuate noise with no deleterious effects on signals. The operations of the SMARTem receiver system are controlled by a Microsoft Windows program. Aside from standard TEM data acquisition functions, it functions as an 8 channel spectrum analyser and digital storage oscilloscope to aid in the assessment of TEM signals and interference.

Graphic User Interface

SMARTem data is displayed graphically by the receiver in user-selectable styles tailored to each geophysical method. During data collection raw signals can be viewed in multi-channel oscilloscope and spectrum analyser formats. After taking a reading, fully processed SMARTem data is presented in decay or profile form with automatic or manual plot scaling. Raw and stacked waveforms can be routinely recorded to disk for subsequent playback, printout or archival. System parameters are set using simple menus with on-line help screens. All settings are saved automatically to disk.

Intelligent Signal Processing = High Quality Data

Programmable timing circuitry and anti-alias filters provide a wide range of base frequencies and sampling rates for all applications. Fine tuning of base frequency ensures power transmission line interference is optimally attenuated in 50 and 60 hz regions. Waveforms are digitized continuously, not just during off-time, and stored to hard disk. Transformation of TEM data to frequency domain or step response can be achieved with built-in routines. The SMARTem signal processing software has evolved as a result of field testing and research since 1994. It contains powerful algorithms for automatic attenuation of transmission line, sferic, telluric, VLF and other interference. As a result, SMARTem can continue to function in conditions that would render other systems ineffective.

Increase Productivity

SMARTem incorporates a range of features that save valuable time in the field. Oscilloscope and spectrum analyser software provides a unique understanding of signal and interference. Diagnosis of fault conditions in receiver antenna and transmitter is expedited. SMARTem software runs on office or field PCs (in addition to the receiver itself) which can reprocess, display or plot data taken directly from the instrument on a floppy disk or tape. Acquired data is stored on the SMARTem in a formats which can be easily tailored to individual users.

Introduce SMARTem to Your Exploration Problems

The SMARTem receiver system is fully compatible with the Zonge, Geonics and Iris range of battery and generator-powered transmitters. Transmitters can be controlled directly from the receiver, or remotely using the SMARTem Transmitter Controller unit. Synchronisation of receiver and controller, using stable crystal oscillators is carried out automatically by software. The SMARTem receiver computer is powered from an internal NiMH battery pack. Supplied with the SMARTem are: Transmitter Controller (optional), operations manual, charger for internal battery pack, USB flash drive (Win98 compatible), power cable, synchronization cable, transmitter control cables and Pelican transport cases.
