EMCview PC software for EMC pre-compliance testing


The Tekbox EMC compliance software EMCview for PCs is a user-friendly EMC pre-compliance testing of radiated and conducted emissions. It is a perfect complement for automated testing using our LISNs, RF current probes, measurement antennas and TEM Cells.

A built-in amplitude correction enables correction and conversion coefficients for cables, amplifiers, attenuators, LISNs, TEM cells, antennas, RF current probes, filters and any other component in the signal chain.

There is no need for a time-consuming setup. The SW is ready for measurements straight after installation. All emission related standards and a few automotive manufacturer standards are pre-configured in corresponding project files. The project files take care of all necessary settings to conduct standard compliant measurements. Besides using pre-configured projects, the user can easily create his own projects using a built in editor or any simple text editor.

The graph supports two complete measurement runs such as for example Average / Quasi-Peak or Peak / Quasi Peak and in addition a fast Quasi-Peak scan of critical peaks. Graphs can be saved and overlayed with newer measurements to track and document design modifications.

Furthermore, EMCview together with our GPS receiver can be used to carry out RF-coverage measurements. An export feature creates KML files which links the result to google maps.
Immunity testing is supported with dedicated menus, controlling the tracking generator of the spectrum analyzer.

EMCview PRO, offers real-time measurement support for spectrum analyzers with real-time capability. Furthermore, EMCview PRO offers advanced conducted immunity testing features for spectrum analyzers with tracking generators. The customer can select between a standard EMCview license or EMCview PRO. Users with a standard EMCview license have the option to upgrade to EMCview Pro.
