Product Overview

The SMM3000X series is a precise Source/Measure Unit (SMU) instrument that can simultaneously output and measure voltage and current. It integrates the functions of a current source, voltage source, voltmeter, and ammeter within the instrument, allowing for easy switching between these functions.

The graphical user interface (GUI) it employs, along with advanced capacitive touchscreen technology, allows for intuitive operation.

The SMM3000X is the SMU for everyone: a versatile instrument, particularly well-suited for characterizing modern scaled semiconductors, nano-scale devices and materials, organic semiconductors, printed electronics, and other small-geometry and low-power devices.

It is widely used in fields such as research and educational applications, industrial development, testing, and manufacturing.

High-Accuracy Pulse Simulation

In pulse mode, the SMM3000X series supports pulsed current output up to ±10.5 A, with a minimum pulse width of 50 μs. This allows precise emulation of transient operating conditions of power devices, such as switching loss testing for GaN and SiC devices, providing strong support for R&D and validation of wide- bandgap power

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, while automatically measuring and logging each data point. This enables fast characterization of devices such as diodes and transistors, allowing engineers to extract I-V curves and analyze conduction behavior under diﬀerent operating conditions.

Flexible User-Deﬁned Sequences

List mode allows users to deﬁne custom output sequences with minimum timing resolution down to 10 μs. 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 Visualization and Analysis

The SMM3000X series provides multiple 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

Based on an advanced SCPI command set, the SMM3000X supports USB and LAN interfaces for seamless PC connectivity and automation. Users can operate the instrument via a built-in web interface or implement deep custom control using SCPI scripting. In addition, TCP/IP Socket communication is supported for ﬂexible network-based test control and integration into automated test systems.
