Oscilloscope takes centre stage at embedded world 2023

At the company booth 4-218 in hall 4 of Nuremberg Exhibition Centre, visitors can learn straight from the experts about various testing aspects for embedded designs: such as testing digital design and interfaces, power electronics, electromagnetic compatibility, wireless connectivity and in-vehicle networks.

Next generation oscilloscope for accelerated insight

Centre stage will be the new R&S MXO 4 series, the first in a new generation of oscilloscopes. The four-channel oscilloscopes feature a brilliant 13.3-inch full-HD capacitive touchscreen, while delivering a number of industry firsts: The R&S MXO 4 claims the fastest real-time update rate of 4.5 mil waveforms/s, letting development engineers see more signal details and infrequent events than with any other oscilloscope. The 12-bit ADC has 16 times the resolution of traditional 8-bit oscilloscopes at all sample rates. And a standard acquisition memory of 400 Mpoints on all four channels gives them 100 times the standard memory. At embedded world, visitors can experience the R&S MXO 4 first-hand in a serial protocol and decode setup, showcasing its new CAN XL trigger and decode capability.

Signal integrity test in high speed digital designs

High speed digital interfaces are at the core of electronic designs. Increasing data rates and growing integration density create new challenges for designs at the IC, board and system level. Trade show visitors can learn about powerful tools for system verification and debugging as well as compliance testing for signal integrity in interfaces, PCBs and interconnections. Demo setups at the Rohde & Schwarz booth include signal integrity interface testing featuring an advanced eye diagram, as well as high-speed digital interface compliance testing of a DDR4 design, both using the R&SRTP oscilloscope. A measurement of high-speed differential signal structures with accurate probe de-embedding is showcased using an R&SZNB vector signal analyser including probes and demo board.

Power electronics testing

The performance of power converters, stable and clean power rail signals, and qualified components within an embedded design are essential to reliable electronic devices. For instance, measuring the current consumption of battery-operated devices in all phases and during the transition from sleep to active modes is important for design engineers. To this end, Rohde & Schwarz demonstrates battery modelling and simulation with the R&SNGU source measure units from the R&S Essentials portfolio. Both R&SLCX LCR meters from Rohde & Schwarz and MFIA impedance analysers from Zurich Instruments AG – a subsidiary since 2021 – showcase component characterisation capabilities.

Detecting electromagnetic interference

Since all electronic controllers are prone to conducted or radiated electromagnetic emissions, many finished electronic products fail EMC compliance testing the first time. Every day spent debugging, isolating and correcting the EMI problem increases the time to market. As a leader in EMC testing, Rohde & Schwarz demonstrates solutions that integrate EMI testing into the product design process. Trade show visitors can learn how to use the R&SRTO6 oscilloscope as powerful tool for EMI debugging, or the R&SFPL1000 signal and spectrum analyser for EMC pre-compliance testing.

Wireless connectivity testing

Many applications and devices such as wearables or IoT devices integrate embedded designs that feature wireless technology. The fast transition to Wi-Fi 7 supporting extreme high data rates and the advent of precise location and secure ranging applications powered by UWB, drives the demand for automated test solutions with extraordinary RF test capabilities for all phases of the product life cycle. Rohde & Schwarz will exhibit two tried-and-tested radio communication testers: The R&SCMP180 in a Wi-Fi 7 test setup showcasing IEEE 802.11be-compliant operation, and the R&SCMP200 for UWB Fira certification testing.

In-vehicle networks testing

ADAS, infotainment and 5G developments are driving up automotive data rates and have made Ethernet the de-facto technology for in-vehicle networks. However, as data rates increase, ensuring the performance and interoperability of cables and components becomes increasingly important. Testing against industry standards such as OPEN Alliance is critical for manufacturers before a product release.

A multi-gigabit automotive Ethernet compliance testing setup featuring the R&S RTP oscilloscope will be on display at embedded world. Automotive customers will also find the latest solutions for battery testing and battery simulation, based on the company’s R&SNGM200 power supply series.
