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 link 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.

EMCview currently supports the following spectrum analyzers

  • Rigol (DSA and RSA)
  • Siglent (SSA/SSA plus/SSA -R and SVA) Siglent EU, Siglent USA
  • R&S (FPC and FPH)
  • OWON XSA, HSA and NSA series
  • Teledyne Test Tools T3SA series
  • BK Precision 2683 series
  • ComPower SPA-900TG series
  • Multicomp MP700xyz series
  • TheEMCShop ESA series
  • UNI-T UTS3000 and UTS1000 series

The spectrum analyzer should be equipped with the EMI option.

Tekbox offers two license options:

  • Analyzer-coupled – the license is coupled to the serial number of the spectrum analyzer. It can be installed on any number of PCs, but it can only control one dedicated spectrum analyzer
  • PC-coupled: the license is coupled to the Host ID of the PC. It can control any of the supported spectrum analyzer models, but it can only be installed on one dedicated PC.

NOTE: Software limitation without a license: the measurement is limited to the frequency range below 10MHz
