At EMV in Stuttgart, Rohde & Schwarz will demonstrate highlights such as the new R&S ELEKTRA EMC test software for automated certification and precompliance tests and R&S AdVISE for automated visual checks. Brand new are the test solutions for spurious emission measurements for 5G components.
Rohde & Schwarz presents its comprehensive range of EMC T&M solutions – from individual instruments to customized systems. Rohde & Schwarz also offers spectrum analyzer based solutions for detecting interference signals during the development phase of electronic equipment. The T&M expert also provides measurement software designed specifically for precompliance and certification measurements as well as accessories such as broadband amplifiers, RF switch units and test antennas. Rohde & Schwarz will present the solutions March 19 to 21, 2019, at EMV in hall C2, booth 619 in the Stuttgart exhibition center.
Automated Precompliance Tests and Certification
EMC certification of electronic instruments is costly and time-consuming. The new R&S ELEKTRA EMC test software from Rohde & Schwarz forms the basis for efficient automated test systems with modern user interfaces. R&S ELEKTRA was launched two years ago with the R&S ELEMI-E base module for EMI measurements during development. The new R&S ELEMI-A and R&S ELEMI-S modules for precompliance and certification measurements now allow electromagnetic interference emissions (EMI) to be automatically tested with a determinable degree of automation. The modules are ideal for EMC certifications in line with current commercial and military standards as well as the automotive industry's EMC standards.
The new R&S ELEMS-C and R&S ELEMS-R options allow R&S 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. R&S 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.
Rohde & Schwarz will showcase precompliance tests and certification measurements at EMV 2019. For precompliance tests, R&S 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.
R&S 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 will also be showcasing the R&S FSWT26 test receiver for measuring compromising emissions in line with the relevant regulations.
Fully Automatic Visual Inspection
Rohde & Schwarz will present 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 recognizes characters, symbols and numbers. Users can also enter threshold values for the event messages. R&S AdVISE is perfectly matched to R&S ELEKTRA, allowing users to analyze events in correlation with the associated frequencies, interference levels and, for example, antenna positions.
Measuring Spurious Emissions in The 5G FR1 Band
Rohde & Schwarz will demonstrate its portfolio for radiated spurious emissions measurements (RSE), which now covers the 5G FR1 frequency range. This includes the latest generation R&S OSP230 open switch and control platform, which has a new powerful and straightforward user interface. The R&S OSP options simplify RSE measurements on mobile communications components considerably, since test routines and filters are adapted to each other. The amplifiers and filters are now designed for frequencies up to 18 GHz and even up to 90 GHz for converters and multiplexers.
Test Solutions for RED
The R&S TS8997 test system tests instruments in line with the Radio Equipment Directive (RED) certification guideline for radio equipment in Europe. The system also offers certification testing in line with ETSI EN 301 893 and EN 300 328 for wireless devices in the 2.4 GHz and 5 GHz band as well as checks in line with FCC §15.247 and §15.407, including DFS tests. The R&S TS8997 tests DUTs with up to eight antennas automatically. It meets or even exceeds the demanding measurement requirements of these test standards.
EMI Debugging in The Development Process
In order to avoid unpleasant surprises during EMC acceptance, it makes sense to eliminate radio interference during the product development phase and adapt the design accordingly. As a genuine multipurpose instrument, the R&S FPC1000, with the R&S HZ-17 near-field probe set and the R&S HM6050-2 impedance stabilization network, is ideal for detecting radiated and conducted interference. The R&S FPC1000 with the R&S ELEKTRA base module, R&S ELEMI-E, is perfect for repetitive measurement procedures and documentation of the results.
The R&S RTO and R&S RTE digital oscilloscope families are also valuable tools for analyzing EMC problems in electronics development. High input sensitivity, a wide dynamic range and powerful FFT implementation are key for recording and analyzing unwanted emissions.
