Test & Measurement

Anritsu has introduced an LTE-V2X PSCCH TX measurement MX887068A-001 software option to enhance the cellular vehicle to everything (C-V2X) measurement function of universal wireless test set MT8870A / MT8872A.

The software supports the physical sidelink shared channel (PSSCH) for LTE-V2X (PC5) and supports RF measurement of the physical sidelink control channel (PSCCH). It also supports mass-production of LTE-V2X (PC5) devices for the evaluation of R&D RF test items.

LTE-V2X (PC5) will co-operate with the other radio access technologies such as 5G V2N (vehicle to network) and the Global Navigation Satellite System (GNSS) and is expected to be adopted for Connected Autonomous Vehicle applications.

Japan, Europe and China are investigating introduction of V2X to the New Car Assessment Program (NCAP). RF evaluation of V2X is becoming increasingly important from the safety aspect. V2X communications technology is used for dedicated short qrange communications (DSRC), such as intelligent transport systems (ITS). C-V2X using mobile communication technology with a wider communication range is also being investigated.

The Universal Wireless Test Set MT8870A/MT8872A series is designed for developing and mass-production various wireless communication equipment, modules, etc. Installing up to four high-performance test units in the main unit supports a seamless frequency band up to 7.3 GHz with a 200 MHz bandwidth.

Each unit measures independently in parallel, enabling the MT8870A to simultaneously evaluate multiple wireless communications devices.

Anritsu provides communications test and measurement equipment and supports customers to help develop wireless, optical, microwave / RF and digital solutions for R&D, manufacturing, installation and maintenance applications, as well as providing services for network monitoring and optimisation. 

Anritsu also provides precision microwave / RF components, optical devices, and high-speed electrical devices for communication products and systems. The company develops solutions for 5G, M2M, IoT, as well as other emerging and legacy wireline and wireless communication markets.

At EuMW (European Microwave Week) Rohde & Schwarz will present a signal generation and analyser for measurements in the D band that, the company said will “significantly simplify early next generation mobile communications research”.

The The R&S FE170ST (single transmit) and R&S FE170SR (single receive) front end extensions are easy to mount to, and configure with, the R&S SMW200A vector signal generator and the R&S FSW signal and spectrum analyser. The extensions will allow these two instruments to cover frequency ranges between 110 and 170GHz which are key spectrum for beyond 5G, for 6G technology and for future automotive radar applications, pointed out the company.

A test set up for sub-THz research using the R&S SMW200A and R&S FSW can be configured using just three connections (IF, reference frequency and LAN) to integrate the front ends into the base units. All users have to do is enter the IP address in the user interface of the base units. After connection, the front ends are directly controlled by the R&S SMW200A and R&S FSW, because the front ends’ control unit is integrated in their firmware. 

The front ends are compact with a form factor of 152 x 190 x 50mm. In addition, the internal synthesiser provides a local oscillator (LO) so the test set up does not need an additional analogue signal source for “excellent phase noise performance”. 

Rohde & Schwarz also offers smart accessories such as bandpass filters and TX power amplifiers.

The R&S FE170ST and R&S FE170SR frontend solution for D band research will be available by the end of 2022. 

Rohde  & Schwarz is exhibiting at EuMW 2022 (27 to 29 September) at the Milano Convention Centre, Italy, stand number D18.

At this week’s ECOC (European Conference on Optical Communication) in Basel, Switzerland, Keysight and Synopsys demonstrated the industry’s first common electrical interface (CEI) SoC supporting 224Gbits per second.

To accelerate 1.6Tbit per second transceiver designs and pathfinding, Keysight Technologies has introduced 224G Ethernet test products which enable SoC makers to validate next-generation electrical interface technology, said the company, accelerating 1.6Tbit per second transceiver design and pathfinding.

In response to the bandwidth demands in networks and data centres generated b y 5G, AI and IoT, there is a requirement for high speed digital interfaces that support 224Gbits per second, per lane data connection speeds for increased bandwidths and to underpin 1.6Tbit per second interconnect technology, said Keysight. Improved data throughput and efficiency in data centre networks also contribute to reductions in power consumption and cost. Keysight believes it is the only provider of bit error ratio testers (BERTs) capable of generating and analysing 224Gbit per second signals.

This portfolio includes the M8050A BERT, offering 224Gbit per second testing for electrical design and validation of transceiver SoCs used in data centres and networks for transferring large amounts of data at high speeds. It provides signal integrity that enables accurate characterisation of receivers used in next-generation data centre networks and server interfaces, said Keysight. 

Synopsys used the M8050A BERT, M8199 arbitrary waveform generator (AWG) and Infiniium UXR-series oscilloscope to develop and validate 224G serialiser / deserialiser (SerDes) IP designs.

“High-performance computing systems depend on high-speed, low-latency interfaces to process massive amounts of data with minimal power,” said John Koeter, senior vice president of marketing and strategy for the Solutions Group at Synopsys. The high speed Ethernet IP provided used Keysight’s digital interface test to validate the performance of the PHY IP. As a result, designers could meet their design and system-level requirements for high-performance computing, networking and AI SoCs, said Koeter.
