SIGLENT Technologies releases SMM3000X Series Source/Measure Unit (SMU). SMM3000X features 6½-digit resolution, output capability of up to ±210 V DC voltage, ±3.03 A DC current, and ±10.5 A pulsed current, with programming and measurement resolution down to 10 fA / 100 nV, and a maximum acquisition rate of 100,000 points/s.
The SMM3000X supports four-quadrant operation, enabling simultaneous sourcing and measurement for closed-loop operations on devices under test (DUTs). It functions as a voltage source, current source, voltmeter, ammeter, and ohmmeter, while also supporting pulse generation and arbitrary waveform output. This makes it an ideal platform for characterising semiconductors and other non-linear devices and materials.

High-Accuracy Pulse Simulation
In pulse mode, the SMM3000X series supports pulsed current output up to $\pm10.5\text{ A}$, with a minimum pulse width of $50\text{ \mu s}$. This allows for the precise emulation of transient operating conditions in power devices—such as switching loss testing for GaN and SiC devices—providing robust support for the R&D and validation of wide-bandgap power semiconductors.
Linear and Log Sweep Functions
The SMM3000X supports linear, log, and pulsed sweep modes. Users can define start and stop values with fixed step sizes to source voltage or current point-by-point, whilst automatically measuring and logging each data point. This enables the rapid characterisation of components such as diodes and transistors, allowing engineers to extract I-V curves and analyse conduction behaviour under various operating conditions.
Flexible User-Defined Sequences
List mode allows users to define custom output sequences with a minimum timing resolution of 10\mus. Parameter changes can be linear, non-linear, arbitrary, or user-ordered. The SMM3000X outputs voltage or current according to the defined list while synchronously measuring and recording data—ideal for non-uniform sweeps, multi-segment tests, and complex stimulus profiles.
Data Visualisation and Analysis
The SMM3000X series provides several display modes, including Graph, Roll, and Measure views:
- Graph View: Enables real-time plotting of mathematical results.
- Roll View: Displays time-domain waveforms of acquired data.
- Measure View: Provides statistical analysis of traces.
These views offer multi-dimensional insight into test results, making data interpretation and debugging more intuitive.
Efficient Remote Programming and Control
Built on an advanced SCPI command set, the SMM3000X includes USB and LAN interfaces for seamless PC connectivity and automation. Users can operate the instrument via a built-in web interface or implement bespoke control using SCPI scripting. Additionally, TCP/IP Socket communication is supported for flexible network-based test control and integration into automated test systems.
The SMM3000X series is designed to meet the precision testing requirements of third-generation semiconductors, advanced optoelectronic devices, and emerging materials. It also significantly accelerates development cycles for new-energy batteries and high-density integrated circuits. By improving both test efficiency and measurement accuracy, it provides a powerful foundation for product development and innovation.
