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 and TEM Cells.

A built-in amplitude correction enables correction and conversion coefficients for cables, amplifiers, attenuators, LISNs, TEM cells, antennas, RF current probes, striplines and capacitive coupling clamps.

There is no need for a time-consuming setup. The SW is ready for measurements straight after installation. All emission related CISPR-xx (EN550xx) measurements and a few automotive manufacturer standards are pre-configured in corresponding project files.

The graph supports two complete measurement runs such as for example Average / Quasi-Peak or Peak / Quasi Peak and alternatively a fast Quasi-Peak scan of critical peaks.

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 a menu controlling the tracking generator of the spectrum analyzer

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 and HSA
  • Teledyne Test Tools T3SA series
  • BK Precision 2683 series
  • ComPower SPA-900TG series

The spectrum analyzer should also be equipped with the EMI option.

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


  • numerous pre-configured project files for CISPR-xx (EN550xx) emission measurements
  • Graph supports two complete measurement runs, same as in test house
  • fast Quasi-Peak scan of critical peaks, immune to frequency drift of the selected peaks
  • configurable limit lines and segment files
  • configurable correction files for cable, LISN, amplifier, antenna etc.
  • configurable margins for the identification and selection of critical peaks
  • supports import and overlaying of reference measurements for comparison purpose
  • linear or logarithmic frequency axis
  • automatic creation of test reports
  • many import/export-functions
  • RF coverage measurements
  • tracking generator control for immunity testing


  • in house measurement of EMC behavior during product design phase
  • EMC training in lab, school and university
  • pre-compliance test of products before submitting it to the test house
  • test cost reduction
  • reduced time to market
