The most advanced high-voltage probe series PVX has established its first 4KV model, the PVX4KV, as the best solution to meet the growing demands of power electronics design, such as low-side VDS measurements in dual-pulse testing of high-speed high-voltage switching devices using silicon carbide technology, as well as IGBTs, thyristors, fast-switching HV diodes, and the like.
All PVX series models are designed to provide precise and consistent results, enabling designers to confidently optimize the efficiency and performance of their power electronic systems.
With low input capacitance and bandwidth exceeding 600MHz, the PVX series ensures accurate and reliable measurements of fast-switching devices and power electronics, making it an essential tool for engineers to perform advanced designs in protected testing environments.
The PVX series probes have a universal BNC output connector and are compatible with any laboratory oscilloscope with the first-order input impedance.
For high-voltage safety reasons, PMK's PVX series probes are not suitable for handheld use, nor for integration into fully automated or manual test stations. Therefore, all PVX probes are used as voltage measurement elements of test systems (permanently attached devices).
The probe series impresses with its innovative and compact form factor. In various applications, high signal fidelity is ensured through individual contact by replacing spring tips and various high-voltage contact accessories. In particular, the unique ground loop, which can rotate 360 degrees, allows direct contact with a 5.08mm asphalt tip without adding any extra capacitive load, maintaining the DUT's highest signal fidelity. Additionally, there is a wide range of soldering adapters, BNC adapters, and other accessories to facilitate and preserve connections to this non-handheld probe.
Each voltage model comes with different cable lengths and configurations, without intelligent readout functions, and without additional high-power measurement silicon insulation (S). Optional readers (RO) feature intelligent communication functions, automatically scaling on the oscilloscope display. Fully equipped models feature intelligent readout and additional silicon-insulated endpoints - S-RO.
