Why should you be concerned with your product’s power system voltage and current harmonics? From an engineering perspective, harmonics produce excessive heat in equipment that causes significant damage and results in inefficient operation. From a business perspective, compliance is an absolute requirement for entry into global markets. To minimize or eliminate these issues and establish acceptable levels of harmonics, numerous power quality standards with specifications and limits for harmonic distortion, such as IEEE 519-2014 and IEC61000-3-2, have been introduced. During this webinar, attendees will gain knowledge on the inner workings of harmonics, learn best practices for accurately measuring harmonics, learn to recognize and distinguish the critical difference between DFT and FFT, and discover important measurement tradeoffs across various test equipment.

There are countless technologies available for optical communications devices and systems validation. With so many specifics to take into consideration, it's not always easy for an engineer to determine the best networking and fiber optic measurement solution to address their measurement needs.

Key discussions in this on-demand webinar include:

• The what, why, and how of available options like optical spectrum analyzers, optical wavelength meters, optical power meters, variable attenuators, fixed and tunable laser sources, and more
• How to improve the quality and value of results for both active and passive optical devices
• Ways to streamline productivity and reduce costs while also achieving higher data transmission rates, longer-distance transmissions, immunity to EMI, lower signal loss, lower latency, enhanced security, and improved energy efficiency
• Trends driven by applications such as AI, quantum, and inter-satellite laser communications (i.e., space lasers!)

Increasing demands for greater network bandwidth and expansion of 5G wireless backhaul has driven data rates to 400G, 800G, and beyond. Starting with the physical layer of the optical network stack, precision measurement of these light speed signals is crucial.

With motors responsible for approximately half of the world's electric energy consumption, identifying opportunities to increase system efficiencies is more important than ever. Improving and innovating motor and inverter technologies is key to enable and further global decarbonization.

During this webinar, engineering professionals with a focus in design, systems, or testing of motor and inverter systems will learn how to more effectively benchmark energy efficiency through accurate power analysis.

Key topics include:

• Steps for precise high-accuracy power and energy measurements on an electric motor and inverter system
• Critical measurement points of inverter input, inverter output, and motor output in a motor and control system
• How voltage, current, and frequency translate into speed, torque, and power (output of the inverter and motor)
• Bringing it all together to effectively measure motor, inverter, and overall system efficiency

While DC power measurements are relatively straight forward, AC power measurements that include distorted waveforms, varying power factors, and multiple phases can add complexity to an otherwise simple measurement.

During this fundamentals webinar, Yokogawa Test&Measurement covers several power measurement subjects including multi-phase measurements, measurement techniques, measurement applications, real-world examples, and more.

You know the basics of electrical power measurements, have set up your dyno, and made key measurements – which is great. But as your motor and drive projects progress, the complexities of system drive requirements can change frequently. Control algorithms, networked communications, and mechanical systems form a complex web of interactions that need sorting. This 60-minute webinar explains how to get past ground-level measurements and delve into comprehensive solutions that leverage test and measurement instruments including power analyzers, high-speed data acquisition, and real-time software.

Topics include:

• How to avoid the “gotcha's” of inverter-based measurements
• Computations for field-oriented control
• The integration of CAN bus communications
• Correlations in the frequency domain
• Other advanced motor and drive topics

The technical presentation includes an audience Q&A.

As energy efficiency becomes an important consideration for governments, industries, and markets, engineers are looking to maximize product efficiency by optimizing power consumption and reducing losses in every process. Accurate measurement of power is an important element of quality control from the design phase all the way through to production and field operation.

A vision of self-driving cars propels the research and development of automotive LiDAR, a vital hardware providing distance and velocity information of a vehicle’s surroundings. Some LiDAR concepts are already heading toward production for automotive ADAS and industrial markets. Two newer concepts promise the greatest potential yet: frequency-modulated continuous wave (FMCW) LiDAR and time-of-flight (TOF) flash LiDAR. However, there are engineering challenges impeding their full adoption. This webinar reviews operation principles and challenges of different LiDAR concepts, a brief discussion on the LiDAR market, and a review of critical optical components such as photodetectors and sources.
