Rohde & Schwarz readies test line up for embedded world

8th June 2022

Rohde & Schwarz will show an array of its latest test solutions at embedded world 2022 in Nuremberg (June 21 to 23), 2022.

A highlight is the new generation of the R&S RTP high-performance oscilloscope, which combines high-class signal integrity measurements with fast acquisition for real-time analysis.

The new models of the most compact instruments of its class come equipped with a bigger and brighter 13.3-inch full HD touchscreen and a fully redesigned front panel.

At embedded world, a 16 GHz bandwidth model of the R&S RTP will be on display performing time domain reflection (TDR) and transmission (TDT) analysis, which supports the characterisation and debugging of signal paths, including PCB traces, cables and connectors.

The TDR/TDT software includes a wizard that guides the user through setup, calibration and analysis. Another setup will show compliance and debugging measurements of an HDMI 2.1 cable.

Utilising the R&S ScopeSuite Compliance Test framework, the R&S RTP executes automated tests with image-based guidelines and summarises results in a test report for various high-speed digital interfaces.

A crucial aspect when designing embedded systems is power supply and its implications. When debugging and validating power rails, for instance, it is essential to ensure that power integrity requirements are met.

The inherent low noise of the recently introduced R&S RTO6 oscilloscopes enables accurate power integrity measurements at the millivolt level. The fast update rate of the oscilloscope allows to quickly see infrequent ripple as well as periodic and random disturbance (PARD) anomalies.

Part of the setup is the R&S RT-ZPR, an oscilloscope probe for characterising power rails with its high bandwidth, high sensitivity, very low noise and an extra-large offset compensation.

Another recent addition to the Rohde & Schwarz portfolio on display at embedded world is the R&S LCX LCR meter, a high-performance general-purpose impedance tester for a wide range of applications.

The meter measures inductance (L), capacitance (C) and resistance (R) of components within the supported frequency range from 4 Hz to 10 MHz.

In combination with an external sweep tool, users can measure the impedance curve over frequency of an electrolytic component. Other parameters like test voltage or test current can be used as sweep parameter.

For automated certification and precompliance tests Rohde & Schwarz is also showing its R&S ELEKTRA EMC test software. The software is available in several versions: with interactive test sequences for developers or as fully automatic EMC test software for device certification.

With the rise of the IoT, different wireless technologies find their way into embedded systems.

For testing Bluetooth Low Energy (LE) devices and wearables, Rohde & Schwarz will present a future-oriented Bluetooth LE over-the-air test solution, for which no control cable is required. This signalling solution is based on the R&S CMW test platform and enables quick preconformance tests over the air in the shielded chamber R&S CMW-Z10.

Additionally, the platform offers all preconformance tests for Bluetooth Classic and Bluetooth Low Energy direct test mode (DTM) up to Rel. 5.2.

On demonstration duty is the R&S CMP180 radio communication tester, a future-proof non-signalling testing solution for wireless devices in research and development, validation and production.

Together with advanced frequency, bandwidth and RF capabilities, it enables testing of the latest wireless technologies such as Wi-Fi 6E, Wi-Fi 7 and many more. And with the R&S CMP200 radio communication tester, a full range of ultra-wideband (UWB) test solutions for R&D, certification and production is provided. UWB's accurate ranging capability and low power consumption combined with high security and reliability makes it suitable for many automotive applications such as remote access and gesture recognition.

For an ever-increasing range of in-vehicle networks, the simple unshielded twisted-pair (UTP) network technology of automotive Ethernet provides a flexible solution. The R&SRTP high-performance oscilloscope provides a fast and efficient means to verify, commission and troubleshoot designs based on an automotive Ethernet communication link of various standards, from today’s 1000BASE-T1 to tomorrow’s MultiGigabit.

The instrument measures and verifies compliance to the standards, and decodes the messages and reliably triggers on them.

For speeds of 1Gbps and higher, electromagnetic interference (EMI) becomes increasingly critical and can potentially threaten the integrity of other communications within the vehicle. As the industry moves towards much faster speeds, for example 2.5Gbps, 5Gbps or even 10GBASE-T1, the OPEN Alliance TC9 group is now focusing on shielded cabling in order to minimize emissions.

Rohde & Schwarz is showing a set for compliance tests according to the TC9 specification for 10GBASE-T1 STP coaxial cables using the four-port R&S ZNB vector network analyser.
