Keithley 2611B System SourceMeter®: Precision Integrated Testing Solution

Product Overview
In semiconductor device characterization, nanomaterial research, and high-precision sensor testing, traditional test architectures typically require separate power supplies and measurement instruments, leading to system complexity and unavoidable errors from lead resistance and switching disturbances. The Keithley 2611B System SourceMeter® (now under Keysight Technologies) addresses these challenges with its highly integrated design, combining the functions of a precision power supply, true current source, digital multimeter, pulse generator, and electronic load into a single instrument, providing an exceptional all-in-one solution for scientific research and high-end manufacturing.

To ensure such precision instruments consistently deliver accurate excitation signals and reliable measurement data, professional calibration and maintenance support are crucial. The Shenzhen Bao'an Shajing Fangfengrui Instrument Equipment Business Department offers professional technical support and services for precision measurement equipment, assisting 2611B users in maintaining optimal performance.

2611B: Achieving Higher Accuracy and Efficiency Through Integrated Architecture

The core value of the SourceMeter lies in its synchronous "source and measure" capability, utilizing a 4-wire (Kelvin) connection method to fundamentally eliminate the effects of lead resistance.

Core Performance and Technical Features:

1. Powerful Sourcing and Measurement Capabilities

   • Voltage source: Outputs ±40 V

   • Current source: Outputs ±1 A (up to ±2 A in pulse mode)

   • Digital multimeter: Precise measurement of voltage, current, and resistance, with current measurement resolution as low as 100 aA (attoampere, 10^-16 A)

   • Supports both DC and pulse mode output, with minimum pulse width of 5 μs, meeting the testing needs of devices sensitive to self-heating effects (e.g., power GaN HEMTs, advanced CMOS devices)
