Yokogawa Test & Measurement Corporation has released its PBDH0400 series differential probe with a maximum input voltage of 2000 V and a frequency bandwidth of 400 MHz.

The probes can deliver the measurements required for developing the next generation of higher speed power devices.

To perform accurate waveform observation of the faster changing signals prevalent in EVs and clean energy applications, the PBDH0400 probes measure voltages over 1000 V and offer a wide frequency range from DC to 400 MHz.

This capability is beneficial for developers of next-generation inverters, enabling the accurate observation of tiny changes in high-speed switching signals. Excellent noise resistance allows the detection of events that can cause unexpected anomalies, including waveform overshoot and ringing.

Initially, two models of the PBDH0400 will be available: the 702922 with a maximum input voltage of 2000 V and the 702921 with a maximum input voltage of 1000 V.

The PBDH0400 series features the Yokogawa probe interface, saving cost and installation space by eliminating the need for an external power supply when connected to a Yokogawa oscilloscope.

Target markets include in-vehicle electronic systems, electronic devices, inverters, power-generation devices, domestic electronic systems like household appliances and air-conditioners and industrial devices.

Applications include: high-precision evaluation of high-speed, high-voltage switching signals exhibited by SiC devices and insulated-gate bipolar transistors (IGBTs) within EV inverters; power analysis and operational confirmation of SiC and gallium nitride-based power electronics; design and assessment of electrical and electronic circuits; and analysis and testing of industrial devices, such as high-efficiency motors, robots and sensors.
