Next-Gen oscilloscopes are been shelved with the advent of EVs and 5G moving ahead from test-beds. Testing these new technologies needs more sophisticated system control, serial bus communication technology. Speaking during an exclusive interview with Niloy Banerjee | Consultant Editor | BISinfotech, Kritikesh Kumar| Business Head – South Asia | Test & Measurement Business Division | Yokogawa India Limited traverses across Yokogawa’s stance and strategies to tap these emerging trends and how they have been providing comprehensive solutions in this field. Edited Nub.
Q1) Firstly, the automotive sector has been deemed to be the driving growth for the oscilloscopes market. What is your opinion on this? Any other domain that you reckon where oscilloscopes are making a mark.
Yes, the automotive sector has been one of the most important drivers for the oscilloscope market and it will be in the future too.
As a company, we are focusing on the overall power electronics industry, which includes various sectors such as automotive, industrial robots, HVAC, clean energy and others. All those industries are important for us, but the automotive industry is particularly so because of the volume and wealth of measurement opportunities, such as the battery, inverter, and motor testing in electric vehicles (EVs) and in-vehicle serial bus communication evaluation.
Q2) What key factors do you predict will be a challenge to the industry?
One of the biggest challenges is to realize both energy efficiency and reliability of the system. For example, in EV development and testing, as the electrical energy used in EVs increases and new fast-switching, energy-efficient power devices get used more widely, then the noise environment becomes more severe and it can affect controlling signals used in EVs.
Yokogawa provides comprehensive solutions from oscilloscopes for control and communication signal measurement to power analyzers for energy efficiency measurement.
Q3) What opportunities do you reckon will advent with the arrival of 5G technology?
We believe that 5G is an emerging technological area, but it is not currently a target of our oscilloscope business.
Q4) Few trends that will be popular in the oscilloscope market?
Led by the demand of more sophisticated system control, serial bus communication technology will advance. It will become faster and more diversified. Therefore, the solutions for serial bus analysis features of oscilloscopes will also need to be enhanced in general.
Yokogawa has anticipated this trend and has been providing comprehensive solutions to this field. One type of solution is oscilloscopes with powerful serial bus analysis features. Another one is ScopeCorder (explained below) with bus monitoring features for multi-channel, high-speed, long-time data logging.
Q5) What new development is your company working on aligning with the current market trends?
We are not trying to provide just more general-purpose oscilloscopes. What we would like to do is to solve the problems of our target customers through providing optimized measurement instruments for them.
Yokogawa oscilloscopes have been developed based on the needs of automotive and other industries where we have been providing total measurement solutions along with the other measurement instruments for a long time. As a result, our oscilloscopes have got to have outstanding, unique, and sophisticated features that contribute to productivity improvements, such as ultra-long memory and a wealth of input channels that realize comprehensiveness in measurement, intelligent analysis functions for dedicated applications such as in-vehicle serial bus measurement, and many other features.
We also provide isolated input, modular type oscilloscope products called “ScopeCorder”. The concept of this series of products is very unique. They not only have high-speed sampling capability like oscilloscopes but can also record for a long time like recorders. A variety of input modules enables multi-channel, comprehensive measurement in one unit. The ScopeCorder devices can accept a wide variety of signals including voltage, current (measured via probes), temperature, frequency, rotation, vibration, acceleration, strain and others. Even analog values carried by the CAN/LIN/SENT bus can be extracted, then displayed and recorded along with other analog waveforms.
ScopeCorder units also have a powerful, real-time calculating function with dedicated processors realizing the instantaneous conversion of the measurement signals into more valuable ones such as energy, rotating position, efficiency, and others.
Q6) What are Yokogawa India’s focus areas and strategies to capture this bullish market?
We are focusing on automotive electronics, motors and drive manufacturers, education, and semiconductor and embedded-system technologies, especially for precise measurement and data acquisition. Major applications include motor characteristic and efficiency testing, high-efficiency inverter design and manufacturing, testing of engines in the transportation sector, and data acquisition at high speeds.
Q7) What are the key offerings for the Indian market?
Yokogawa oscilloscopes combine a mixed signal oscilloscope and portable data acquisition recorder into a modular platform designed to capture both high-speed transients and low-speed trends. They also include standard math and several advanced real-time analysis functions are available. They are basically designed for engineers working in the automotive and railway industry where a common measurement challenge is to combine measurements of electrical signals and physical performance parameters indicated by sensors together with CAN/CAN FD bus, LIN bus or SENT data transmitted by the powertrain management system. We address the challenge of combining the measurement of all signals to provide a thorough insight into the dynamic behavior of the electromechanical system. The result is a considerable time saving compared to other approaches such as analysis on PCs or other software.
Q8) Finally, what are your insights into the Indian T&M market?
Major investments in the renewable power sector by the Government of India calls for higher efficiency products, which could be tested by our power analyzers for efficiency, our ScopeCorders for long term data monitoring and acquisition, and basic instruments for maintenance. Also, the introduction of EVs in the public transport systems under the FAME (Faster Adoption and Manufacturing of (Hybrid) and Electric Vehicles in India) scheme creates demand for our power analyzers to measure the inverter efficiency and mechanical efficiency of the motors, high speed recorders for multi-channel long-term data monitoring and acquisition, and basic instruments for field use. The government will also set up incubation centers for start-ups working in the EV space, which will support demand for T&M products with value-added functionality.
