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.

Immunity testing is supported with a menu controlling the tracking generator of the spectrum analyzer

Features


  • New IEC 61000-4-20  (G)TEM Near Field measurement correlation to FAR field
  • Many 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

 

Application


  • 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
