Tektronix expands power measurement portfolio with new wideband shunts and high voltage differential probe

Tektronix today unveiled two additions to its power measurement portfolio: the wideband shunt for IsoVu™ isolated current probes (250MHz) and the THDP0400 high voltage differential probe (400MHz, ±2000V).

The launches address a growing challenge in power electronics design. As silicon carbide (SiC) and gallium nitride (GaN) technologies push switching speeds higher across EVs, industrial systems, AI data centers and advanced power conversion applications, engineers are being asked to validate systems operating at higher voltages, faster edge rates and lower currents, where accurate shunt-based current measurements are becoming increasingly critical. Traditional measurement approaches can struggle to capture these behaviors accurately without adding complexity, noise, or uncertainty into the measurement itself. Together, the new accessories expand the company’s measurement coverage across the power-validation workflow – from precision low-current measurements to high-voltage switching applications – while helping engineers stay within a single, integrated ecosystem. 

The new wideband shunts for IsoVu isolated current probes are the first shunts in Tektronix’s precision current measurement portfolio – a highly anticipated addition that expands advanced current measurement capabilities. For years engineers using advanced current measurement workflows often relied on third-party shunts to capture low-current transient behavior. The new shunts bring that capability into the trusted Tektronix measurement environment for the first time, creating a more complete and integrated current measurement solution (more info).
