The EMSYS software is a program allowing to transfer, edit, process and export data of the IRIS Instruments PROMIS system (Frequency Domaim ElectroMagnetic system)
The main functions of the EMSYS software are  the following ones:
- Data download
 - Numeric and graphic presentation (set up parameters, magnetic field components,…)
 - Processing (filter on threshold values, reject some frequencies, correct the tilt…)
 - Topography insertion
 - Plot of the In-Phase and Out-of-Phase data in sounding / profiling / pseudo-section
 - Export to various formats (″txt″, ″Ix1D V.3″ Interpex interpretation software)
