Yokogawa Test & Measurement released the PBDH0400 series differential probe, which has a maximum input voltage of 2,000 V and a frequency bandwidth of 400 MHz. Able to deliver the measurements required for developing the next generation of higher-speed power devices, the PBDH0400 Series differential probe addresses the acute need in the power electronics industry to test next-generation power devices.
Implementation of challenging technology like silicon-carbide (SiC) devices demands ultra-precise measurement of high-voltage and higher-speed signals from an ungrounded (floating) potential. These scenarios require differential probes instead of standard probes.
Yokogawa's wide-bandwidth differential probe is available in two versions: the 702922 model with a maximum input voltage of 2,000 V, and the 702921 with a maximum input voltage of 1,000 V.
To perform the accurate waveform observation of faster-changing signals prevalent in application spaces like electric vehicles (EVs) and clean energy systems, PBDH0400 series differential probes measure voltages over 1,000 V and offer a wide frequency range from DC to 400 MHz. This is particularly beneficial for developers of next-generation inverters: They enable accurate observation of tiny changes in high-speed switching signals with excellent noise resistance for the detection of events that can cause unexpected anomalies, such as waveform overshoot and ringing.
The PBDH0400 series has the Yokogawa probe interface, which eliminates the need for an external power supply when connected to a Yokogawa oscilloscope. The probe attenuation ratio is automatically set through the interface so that measurement can start immediately once connected to the instrument. Combining the PBDH0400 with the company's 12-bit DLM5000HD or DLM3000HD oscilloscopes enables more accurate waveform measurements.
