Yokogawa Test & Measurement has released the PBDH0400 series of differential probes, designed to support the development of higher-speed power devices by providing accurate measurements. With a maximum input voltage of 2,000 V and a frequency bandwidth of 400 MHz, these probes cater to the need for precise measurement of high-voltage and higher-speed signals in the power electronics industry, particularly for next-generation power devices utilizing silicon-carbide (SiC) technology.
Due to the increasing focus on energy efficiency in motors and inverters, the demand for ultra-precise measurement from an ungrounded potential has risen. Yokogawa recognized this need and developed wide-bandwidth differential probes to measure high-voltage and high-speed signals effectively. The PBDH0400 series comprises two models – one with a maximum input voltage of 2,000 V (702922 model) and another with a maximum input voltage of 1,000 V (702921 model), enabling accurate observation of small changes in high-speed switching signals.
The PBDH0400 series enhances noise resistance, allowing for the detection of events that could lead to unexpected anomalies like waveform overshoot and ringing. These probes facilitate the precise measurement of high-speed signals, contributing to the development of efficient power devices. Additionally, the probes feature the Yokogawa probe interface, eliminating the need for an external power supply when connected to a Yokogawa oscilloscope, thus saving cost and space. The interface automatically sets the probe attenuation ratio, enabling immediate measurement after connection to the instrument.
In the power electronics industry, the evolution towards higher-speed power devices necessitates advanced measurement capabilities to accurately capture high-voltage and high-speed signals. The PBDH0400 series of differential probes from Yokogawa Test & Measurement addresses this requirement by offering a maximum input voltage of 2,000 V and a frequency bandwidth of 400 MHz, enabling the development of next-generation power devices. These probes support the precise measurement of signals in motors, inverters, and other power electronics applications, contributing to increased energy efficiency through the use of SiC technology.
Yokogawa’s development of wide-bandwidth differential probes reflects the company’s commitment to meeting the evolving needs of the power electronics industry. By enabling the measurement of high-voltage and high-speed signals from an ungrounded potential, these probes cater to the requirements of next-generation power devices and silicon-carbide (SiC) technology. With features such as noise resistance and automatic probe attenuation ratio setting, the PBDH0400 series offers a comprehensive solution for accurate signal measurement and observation in power electronics applications.
Overall, the PBDH0400 series of probes from Yokogawa Test & Measurement represents a significant advancement in the field of power electronics, providing engineers and researchers with the tools needed to develop efficient and high-speed power devices. These probes offer a combination of high input voltage capability, wide bandwidth, and noise resistance, making them ideal for measuring high-speed switching signals and detecting anomalies. By integrating the Yokogawa probe interface, the probes also streamline the measurement process, reducing costs and saving installation space.
