The Keysight B1505AP is a modular power device analyzer and curve tracer engineered for high-power semiconductor device characterization. It delivers measurements from sub-picoamp levels to 1500 A across voltage ranges up to 10 kV, with minimum resolution of 10 fA / 0.5 µV and micronohm-level on-resistance capability. The instrument ships in eight pre-configured packages addressing specific voltage, current, and capacitance requirements, with a 10-slot mainframe supporting plug-in module expansion.
