Yokogawa understands the unique demands of automotive and transportation. As vehicle technology continues to advance in the areas of safety, environmental friendliness, and comfort, Yokogawa test & measurement instruments continue to evolve and advance to support the increasingly complex electronic vehicle components, systems, and innovations. Yokogawa diligently provides up-to-the-minute technologies in Body Control, Safety Systems (ABS, Airbags, Rollover Prevention), Drivetrain performance, development, ECU (Electronic Control Unit), In-Vehicle Entertainment and various others. With foresight, Yokogawa also offers measuring instruments that will lead you into the future in five key areas: Hybrid Electric Vehicle (HEV), Fuel Cells, In-vehicle LAN, Vehicle components and Intelligent Transport System (ITS) equipment. Yokogawa also offers compliance test solutions such as CAN, the de-facto standard, and Advanced Power Analyzers, such as the SB5000 Serial Bus Analyzer with advanced functions for Flex-Ray technology, the protocol for incoming standards. These are just a few of the ways Yokogawa diligently strives to meet your evolving needs.

Overview:

The DL850 can take engineers to a new level of efficiency in the development of everything from green devices to complex advanced systems.

Overview:

The request for lower uncertainties in power measurements are increasing,especially in the transformer industries. Their role is to ensure that the electricity is distributed in an efficient and reliable way. 

Overview:

In recent years, energy-saving instruments including inverters have been actively developed. Researchers in R&D sections want to evaluate their prototypes in real time to enhance the development efficiency. Therefore, measuring instruments are required to have functions for not only simply recording data but also immediately calculating power values and efficiency based on the data. To meet this demand, Yokogawa has developed a unique real-time math function for the DL850 ScopeCorder, our multi-channel waveform recording instrument. This paper gives an overview of the function and its application examples.

Overview:

If a product uses power, then power consumption and power quality measurements must be made as part of product design and test. These measurements are essential to optimize product design, comply with standards and provide nameplate information to customers.
This article will discuss best practices for making these measurements, starting with power measurement basics and proceeding to the types of instruments and associated components typically used to make measurements. The article will conclude with real-world examples, which apply the information imparted earlier in the article to solve practical measurement problems. Although most of us have been exposed to basic power measurement equations, a primer is helpful to summarize this information and to show how it applies to product design and test.

Overview:

There are several factors for a user to consider when using an IEPE accelerometer, particularly when used with newly available integrated signal conditioner/data acquisition systems. Correctly managing these factors will help the user avoid erroneous data from their IEPE accelerometer and ensure the quality of the measurement data is at the level they expect and require.

Overview:

One of the main responsibilities of engineers and technicians is data analysis, and this article will show how multi-touch technologies can be used to improve the performance of this and other related tasks.
