Power Device Analyzer & Curve Tracer
Power device testing faces major challenges, including the need for wide measurement ranges (from pA to kA and uV to kV), fast pulsed measurements to avoid self-heating, and accurate characterization of parameters such as gate charge, junction capacitance, and switching speed at high voltages. Traditional tools like curve tracers lack the required accuracy, speed, and features, while reliability and temperature testing remain complex and inefficient. The Keysight B1505A Power Device Analyzer addresses these issues as a single-box solution, covering up to 1500 A and 10 kV with precise measurements down to the sub-picoamp range. It supports packaged device testing, automated capacitance and gate charge analysis, pulsed measurements, and safe temperature-dependent evaluation from –50 °C to +250 °C. With standardized test fixtures, scalable hardware, and software for streamlined data analysis and reporting, the B1505A greatly improves efficiency, accuracy, and safety in modern power device characterization.
Impedance Analyzer
The Keysight E4990A Impedance Analyzer delivers high-precision impedance measurements from 20 Hz up to 120 MHz, making it a versatile and required solution for the development and extraction of power device characteristics. With its wide selectable operation frequency, this impedance analyzer can also be a valuable tool when designing converters whose stray inductance and parasitic capacitance vastly affect performance, such as resonant DC/DC power supplies. Its advanced measurement capabilities also make it indispensable for evaluating passive components, including capacitors, hand-wound inductors, and transformers, all of which are essential tools in the arsenal of a power electronics engineer. Beyond individual components, the E4990A supports material evaluation and dielectric property testing, which can be critical for advanced insulation and substrate development. With its intuitive user interface, large display, and LAN/USB/GPIB connectivity, it supports remote activity, automated sequences, and custom test procedures, making it a complete and flexible solution for impedance measurements in both research laboratories and industrial environments.
