For several years, vehicle manufacturers and government agencies have sought ways to increase road safety, manage traffic efficiently and, in the future, make driving more comfortable, convenient and safe. Vehicle-to-everything (V2X) is a new generation of information and communication technology that connects vehicles to everything and can support these objectives. V2X is designed to offer low-latency vehicle-to-vehicle (V2V), vehicle-to-roadside infrastructure (V2I) and vehicle-to-pedestrian (V2P) communications to add a new dimension to future driver assistance systems.Cellular V2X (C-V2X) is defined as the communications standard by 3GPP in Release 14 and uses LTE technology as the physical interface for communications.The LTE C-V2X Scanner provides customers an opportunity to verify, test, and optimize ITS traffic systems that are being deployed or are already established. The scanner accomplishes this by passively listening to PC (5.9GHz) messages that are being broadcast from RSU (roadside units), vehicles or any other C-V2X enabled device. Traditional scanner measurements regarding RF signal power and quality such as RSRP, RS-CINR and RSSI, are provided for each physical channel (PSCCH and PSSCH) as well as decoded ITS message content for all three regions (North America, EU, China).

Propagation measurements are indispensable in the planning of digital, cellular mobile radio net-works. To find the optimum sites for the base stations, a mobile test transmitter system simulating the base station is operated from a number of possible locations. The test receiver system is accommodated in a vehicle, which is driven along a test route to perform measurements. The parameters measured, such as level, bit error rate or channel impulse response, provide information on the coverage within the cell. The main problem is to minimize interference caused by multipath propagation in the reception area. The SME offered by Rohde & Schwarz is a universal test generator that can be used as the core of a test transmitter system. The SME generates the GMSK-modulated signals required for GSM propagation measurements in line with the rele-vant standards. Thanks to its low weight of 17 kg it can be carried even to remote sites. Fitted with the new optional DM Memory Extension (SME-B12, in the following referred to as XMEM), the SME is able to store data sequences of up to 8 Mbit which are long enough for receiver measurements with test mobile stations. A suitable test receiver system is for instance a test mobile station for measuring level and bit error rate and the Impulse Response Analyzer PCS from Rohde & Schwarz for measuring the channel impulse response. The present Application Note describes how the XMEM can be loaded with suitable data (test sequence) by the GSM Radiocommunication Test Set CRTP from Rohde & Schwarz and how the SME has to be adjusted for GMSK modulation of these data. First, however, an overview is given of all functions of the XMEM and their operation supplementary to the Operating Manual. Finally, it is explained how the XMEM data can be transferred between PC and SME via the IEEE-488 or RS-232 interface.

All channels of DC power supplies R&S®NGL200 and R&S®NGM200 are isolated against the grounding equipment conductor and against the digital ground of the instrument. Therefore, channels can be connected in parallel for increasing the current capability, or in series for achieving higher voltages or dual-voltage supplies.

This application note is about creating your own battery model for the R&S®NGM200 and R&S®NGU201, beyond the standard models provided within the battery simulation option NGM-K106 and NGU-K106. To get to a battery model, a few steps are required. To determine the parameters for the battery model, it is necessary to discharge a battery using a selected method, to record the data and to calculate the model on this basis. With this software, a connection can be established to the instrument, batteries can be measured using various measurement methods, and a model can then be created from these measurements. These models, which are determined from the measurements, can then be simulated with the power supply, thus creating a digital twin of the battery. Using these, test scenarios can be carried out in a safe and reproducible environment.
