2430 KEITHLEY Digital Source Meter

Overview

Product Overview

The Keithley 2430 SourceMeter® is a multi-function instrument combining precision power supply, current source, voltage source, electronic load, and measurement capabilities. Designed for semiconductor device testing, material characterization, and sensor calibration, its key features include:

Four-quadrant operation: Capable of both sourcing and sinking current to simulate real-world load conditions
High-precision measurement: Voltage resolution down to 1μV, current resolution to 10pA
Pulse mode: Supports pulse widths as short as 50μs for transient power device testing

Core Features

Integrated Source and Measurement

Simultaneously outputs current/voltage while measuring device parameters (V, I, R)
Auto-ranging eliminates manual range switching errors

Four-Quadrant Operation

Source mode (output positive/negative voltage or current)
Sink mode (absorbs current to emulate electronic loads)

High Accuracy and Low Noise

Voltage accuracy: ±0.05% of setting + 200μV
Current accuracy: ±0.05% of setting + 100nA
Low-noise design: <5μV RMS (1Hz-100kHz bandwidth)

Pulse and Sweep Capabilities

Programmable pulses: 50μs-10s width with adjustable duty cycle
Linear/logarithmic sweeps for automated V/I/R scanning

Automation Control

SCPI command support compatible with LabVIEW/Python
Hardware trigger I/O for multi-device cascaded testing
