2611B KEITHLEY Digital Source Meter

2611B Keithley Digital SourceMeter® Detailed Introduction

The **2611B Keithley Digital SourceMeter®** is a high-performance, precision Source Measure Unit (SMU) developed by Tektronix under the Keithley brand. It is widely used in semiconductor testing, materials research, and component characterization. Combining the functions of a precision power supply, current source, digital multimeter, pulse generator, and electronic load, it provides highly accurate voltage/current sourcing and measurement capabilities.

Key Features

1. High-Precision Sourcing & Measurement

• Voltage sourcing range: ±40V, with 1μV resolution

• Current sourcing range: ±10A (pulsed), with 10pA resolution

2. Four-Quadrant Operation

• Capable of both sourcing and sinking power (source and sink modes).

3. High-Speed Pulsing

• Supports pulse widths as short as 50μs, ideal for dynamic device testing.

4. Low-Noise Design

• Optimized for low-current (nA/pA) and high-impedance device measurements.

5. Integrated Functionality

• Programmable via LabVIEW, Python, and TSP (Test Script Processor) scripts.

Typical Applications

• Semiconductor device IV/CV testing (diodes, transistors, MOSFETs, etc.)

• Nanomaterial/thin-film resistance measurements

• Solar cell and LED optoelectronic characterization

• Precision power management IC validation
