The portable TEM instrument system: adopts portable power to achieve a high-current power supply. With essential differences between single pulse power supply can realize high power positive and negative square wave power supply, with multiple stacking, no longer rely on the large power generator sets or large batteries. Working with large current and small coils: adopt high current and small coil power supply, integration advantages of large current positive and negative square wave power supply, exploration depth up to thousands of meters, especially suitable for field construction conditions with poor. At the same time, the field construction costs and efficiency than the traditional large coil method save 60%.IPC as a operation platform of the master machine with Windows: using low power consumption IPC as the operation platform of the computer with Windows, for supply current, pulse width, sampling rate, times stocking, and so on, are all set up by English menu; the massive computer storage space provides the guarantee for large-capacity sampling: measurements of a variety of data in one day, are all exists in computer.
