Description
Overview
The Keysight B1511B is a medium power Source/Measure Unit (SMU) designed for accurate DC current-voltage characterization of semiconductor devices and components. It integrates high-precision voltage and current sourcing with measurement capabilities, achieving down to femtoampere and microvolt resolution.
Key Features
- 4-quadrant source and measurement capabilities spanning 0.1 fA to 1 A and 0.5 µV to 200 V
- Femtoampere-level current measurement resolution with optional Atto sense switch unit (ASU) for sub-fA performance
- Multiple measurement modes: spot, sweep, pulse, and sampling with 100 µs minimum sampling interval and 500 µs minimum pulse width
- Quasi-Static Capacitance-Voltage (QS-CV) measurement with leak current compensation
Applications
- Semiconductor device parameter characterization and testing
- Active and passive component evaluation
- Carbon nanotube (CNT) and nanowire characterization
- Material and surface state analysis
