Tektronix THDP0400

The Tektronix THDP0400 High Voltage Differential Probe enables safe measurement of differential voltages up to ±2000 V. It is well suited for testing IGBT, SiC, and GaN power devices, as well as applications such as motor drives and power converters. The probe provides up to 400 MHz bandwidth with selectable attenuation settings, enabling accurate measurement of fast-switching signals in medium- to high-voltage differential applications.

The THDP0400 model includes a range of standard accessories to simplify connection to the device under test (DUT). Like all probes in the THDP series, it features the TekVPI® interface, allowing seamless connection to 4,5, and 6 Series B MSO oscilloscopes for both manual and automated measurements.
