Introduction

The Keysight Technologies, Inc. B1505A Power Device Analyzer/Curve Tracer is a powerful tool for

measuring and characterizing devices such as insulation gate bipolar transistors (IGBTs). The B1505A’s

power device measurement solution.

The B1505A supports several new external modules that greatly improve its measurement range.

These include: an ultra high current unit (UHCU) with a maximum output of 1500 A, a high voltage

medium current unit (HVMCU) with a maximum output range of 2.5 A/2200 V and an ultra high

voltage unit (UHVU) with a maximum output of 10 kV. These capabilities provide state of the art

precise measurements by eliminating device self heating effects.

The B1505A can also perform accurate capacitance versus voltage (CV) measurement at up to 3 kV of

DC bias. The B1505A makes it easy to directly measure an IGBT’s capacitance parameters.
