SIGLENT SMM3000X: Precision Source Measure UniT (SMU)
The SIGLENT SMM3000X series redefines measuring instrument standards by combining current source, voltage source, voltmeter, and ammeter functions into a single unit. This Source Measure Unit (SMU) allows you to supply and measure voltage and current simultaneously, offering a fast and seamless transition between different test modes.
Equipped with an intuitive Graphical User Interface (GUI) on a high-resolution 5-inch capacitive touch screen display, SMM3000X is the ideal tool for characterizing modern semiconductors, nanoscale devices, organic materials, printed electronics, and low-power components. it is widely used in research, education, and industrial development.

In-depth: STC6P Series Adapters
For critical applications requiring maximum noise shielding, SIGLENT has developed the STC6P adapter series. Designed natively to interface with the SMM3000X series, these connectors transform standard banana inputs into professional triaxial connections.
The STC6P adapters are essential for low-current measurements (below 1 nA), eliminating leakage currents thanks to the use of the "Guard" terminal. They are perfect for easily connecting the SMU to triaxial test fixtures or wafer inspection stations.
- STC6P4W: Banana to Triaxial Adapter, for 4-wire (Kelvin) connections.
- STC6P2W: Banana to Triaxial Adapter, for 2-wire connections.
- STC6P2W-B: Compact 2-wire Banana to Triaxial adapter.
