The SMU4000 Series from Aim-TTi provides quality performance at an affordable price point for a four quadrant SMU.

Integrating a fast and agile, high power four quadrant Voltage/ Current source and precise Voltage/ Current meters in a compact half rack 2U casing, it is capable of precisely supplying positive and negative voltages, sourcing or sinking power, while simultaneously measuring both current and voltage for I-V characterising. 

The Aim-TTi PowerFlex autoranging system provides a semi constant power characteristic so that the current capability rises as the voltage falls. The SMU4000 achieves full instrument output power across the majority of the voltage range, unlike conventional SMUs where the maximum power can only be achieved at the top of each voltage range.

With high current and power combined with fast measurements and low glitch auto ranging speed, it is ideal for industrial development as well as educational environments, identifying the SMU as the all-in-one solution for simplifying test applications such as I-V characterising, semiconductor testing, battery charging/discharging, and much more.

Two models offering max 21V 3A and 210V 3A with the added benefit of the Aim-TTi PowerFlex technology makes the SMU4000 flexible for a wide range of High and Low Voltage requirements.

SMU LINK can be used to connect two SMUs together to perform simultaneously via a handshake triggering system, effectively creating a fully functioning 2 channel SMU, useful for testing three leaded components such as small signal BJT’s, FET’s and others.

Eight EasySet pre-sets are included to allow instant use of the SMU in the simplest form, including: Power Supply, Current Source, Load, Voltmeter, Ammeter, Ohmmeter, Insulation resistance meter and Leakage current meter. These setups form a convenient base, from which settings can be edited using the manual setup mode configuration.

As well as a high precision DC and pulsed source and measure capabilities, the SMU4000 Series has a built-in sweep setting that supports standard sweep parameters, such as: Constant and pulsed sweep operation, double sweep functions and linear & logarithmic modes that are fully functional from the front panel with a simple setup process involving only a few steps, providing full graphical results on screen.

Arbitrary list sweeps of up to 100K points can be directly uploaded to the instrument via the flash drive or Test Bridge SMU software application.

Test Bridge SMU provides full instrument control of multiple SMU's alongside additional enhanced features. The graphical interface allows advanced setups, lists and sequences to be created and directly applied to the SMU. Efficient data download means results can be saved and exported for further analysis as a .CSV file then further viewed in a tabular or graphical format from within the Test Bridge SMU software.
