Automated EMC test systems boost compliance
Rohde & Schwarz is showing new EMC test software for automated certification and precompliance tests as well as software for automated visual checks, including spurious emission measurements for 5G components.

EMC certification of electronic instruments is costly and time-consuming. The R&S ELEKTRA EMC test software forms the basis for efficient automated test systems with modern user interfaces. This was was launched two years ago with the R&S ELEMI-E base module for EMI measurements during development but now the new ELEMI-A and R&S ELEMI-S modules for precompliance and certification measurements allow electromagnetic interference emissions (EMI) to be automatically tested with a determinable degree of automation. The modules are aimed at EMC certifications in line with current commercial and military standards as well as the automotive industry's EMC standards.

The ELEMS-C and R&S ELEMS-R options allows ELEKTRA to control test systems for conducted and radiated susceptibility (EMS). The software performs this calibration and evaluation largely automatically. The generator then produces signals with the right level in line with IEC 61000-4-3 and 61000-4-6. ELEKTRA supports all of the company's current EMC test receivers and relevant spectrum analyzers and, in the long term, will gradually replace the established R&S EMC32 EMC software.

For precompliance tests, ELEKTRA controls the R&S FPC1000 spectrum analyzer, which developers can also use for many other applications. The R&S FPC1000 offers numerous options such as frequency extensions or RF preamplifiers, which can be enabled with a keycode if needed. The R&S FPL1007 spectrum analyzer with the R&S FPL1-K54 measurement application is the perfect diagnostic tool for detecting EMI emissions. Disturbance maxima and critical frequencies are automatically entered in a peak list. Using the CISPR detectors, users can then carry out a final evaluation with respect to official EMI emission limits.

ELEKTRA also controls the R&S ESW and R&S ESR EMC test receivers for certification measurements in line with various EMC standards. The high-end R&S ESW44 test receiver offers excellent RF properties and a high measuring speed in measurement ranges up to 44 GHz. The R&S ESR26 is ideal for measurements up to 26.5 GHz, thus covering most standards for EMC acceptance tests. 

Rohde & Schwarz is also showing version 3 of the R&S AdVISE monitoring and analysis software for video based visual inspection of status displays, signal lights or screens. The software reports changes to the image reliably and automatically. It
