yokoGAWA Adds neW FeAtures to next GenerAtion dl950 scopecorder
ScopeCorder, improving its data acquisition capabilities and adding firmware updatable features. Using the new Flash Acquisition
Y
function, data can be captured over a long time with a high-speed sample rate of 20MS/s (8CH) and 10 MS/s (16CH), which is 100 times faster than the previous model. This optional Flash memory feature makes the DL950 ideal for capturing data at high sample rates anywhere a PC would not be suitable, such as in a vehicle or at a remote site. Applications for this new acquisition feature could include
recording control signals and temperature trends or vibrations simultaneously in small spaces, such as inside a car or a train. Other uses could include recording control signals or generated/consumed power in challenging environments, such as spaces near generators in a power plant or restricted volumes in a manufacturer’s factory. In these applications the unit would usually need to be switched off
before moving it to an office to save data on a PC. The flash memory is non-volatile, so the captured data stays stored within the instrument even after turning off the power. Available as an option on new purchases of the DL950 ScopeCorder, the feature can also be purchased as a modification kit for retrofitting existing instruments. The other major new addition to the DL950 is a new firmware version.
This adds new features that allows GPS data to be acquired with the existing /C35 option. Data includes time, latitude and longitude, altitude, velocity and direction. The new firmware also adds new real-time computing functions to the existing /G03 or /G05 option. These functions are CAN ID, IIR filter, angle math, rotary angle, resolver and power math. Also added are new attenuation ratios for both voltage and current probes.

ni expAnds electric Vehicle testinG ecosystem With d&V electronics
traction inverter validation: a new Inverter Test System (ITS) and a collaboration agreement with D&V Electronics for power-level inverter test. These offerings promise to accelerate innovation
N
for EVs by integrating test earlier in the product development lifecycle. By simulating EV powertrains to perform hardware-in-the-loop (HIL) tests of traction inverter electronic control units (ECUs), the ITS allows EV test engineers to create more life-like scenarios not easily and accurately reproduced on the road. For over a century, automotive powertrain engineers focused on
optimising the combustion engine. The arrival of the electric vehicle brings the promise of a sustainable future, but the engineering challenge has proven formidable. NI solutions, coupled with the expertise of D&V Electronics, allow customers to spend more time engineering ambitiously toward Vision Zero and less time troubleshooting their test systems. Through this collaboration between NI and D&V, electric motor and direct current power emulators can be inserted into the test workflow to enable durability and thermal testing of the inverter component at full power in a high quality, cost-effective, and safe environment. Adding more simulation fidelity and capabilities speeds up the entire development process at a lower overall cost than field tests.

I has announced two new offerings to enhance testing environments and workflows for electric vehicle (EV)
The all-in-one Radio Communication Test Station MT8000A is a
5G base-station simulator for 5G RF and protocol measurements as well as application tests. It supports high-order 4×4 MIMO and carrier aggregation (8CA) technologies for fast, large-capacity communications. As well as focusing on smartphone testing, it covers a wide application range, including 5G communications function tests and evaluations of antennas and high-frequency parts. To characterise an antenna, it is necessary to measure its radiation
patterns to determine how well, and in which direction, it radiates. To quickly obtain reliable 3D radiation patterns, antenna performance tests are moving towards Over-The-Air (OTA) test solutions to obtain fast and reliable measurements at the system level. For OTA measurements, the tests are performed through a radio communication tester and are conducted using a near-field measurement method in an anechoic chamber to block external electromagnetic fields and to simulate realistic and complex RF scenarios. Addressing the complexity of measuring highly connected vehicles, MVG offers OTA measurement solutions specifically designed for the complete verification of automotive wireless performance. Thanks to a high precision positioning system (controller and turntable) continuous on-the-fly measurements can be performed. This allows for quick and accurate measurement of directivity, gain and efficiency.

World-First 5G Vehicle otA rF test system
Radio Communication Test Station MT8000A. Realising autonomous driving requires simultaneous communications
A
with the surrounding environment, including other vehicles, road infrastructure, networks, etc. In particular, introduction of 5G supporting large-capacity, low-latency, massive connections are key technology to transferring the large data volumes generated by various sensors, such as vehicle cameras, as well as for 3D high-definition mapping data. Consequently, car manufactures, and Telematics Unit suppliers are pushing forward with development of 5G communications products. The developed 5G communications products are installed in vehicles
as the “connected car”. However, before release, the connected vehicle communications performance must be tested and verified in an OTA environment simulating the actual environment as possible. Now, Anritsu and Microwave Vision Group (MVG) have partnered
to deliver the MT8000A and OTA system to Toyota as the world’s first 5G vehicle OTA RF test system.
nritsu has announced development of the world’s first 5G OTA RF test system in partnership with Toyota and their investment in MVG OTA test environment using Anritsu ‘s
