Bloggen over Marvin Test Solutions Launches GX3104 PXI SMU for Precision Testing

In modern electronic testing, precise voltage and current control and measurement are critical components of device evaluation. Particularly in semiconductor device development, production, and system-level testing, a high-performance Source Measure Unit (SMU) can significantly enhance testing efficiency and accuracy. The GX3104 quad-channel PXI Source Measure Unit from Marvin Test Solutions represents such a solution, combining high precision, multifunctionality, and the integration advantages of the PXI platform.

The GX3104 is a 3U PXI module that provides four independent SMU channels with common ground capability. Each channel supports four-quadrant operation, delivering ±20V voltage output and ±1A current output (with Channel 1 supporting 1A while Channels 2-4 support 500mA, with a total module output current limit of 1A). This design enables flexible handling of various positive and negative voltage and current injection and measurement requirements.

For precision, the GX3104 incorporates 24-bit analog-to-digital converters (ADCs) and 18-bit digital-to-analog converters (DACs). The 24-bit ADC provides programmable resolution ranging from 18 to 24 bits, ensuring fine capture of measured signals. The 18-bit DAC guarantees output accuracy for voltage and current sources. Additionally, the module offers seven current measurement ranges, covering a broad spectrum from ±2.5 µA to ±1 A, accommodating testing needs from weak signals to higher-power devices.

To achieve higher measurement precision, especially for low-level current measurements, each output channel of the GX3104 includes SMU output connections, Kelvin (four-wire) sensing connections, and driven guard connections. Kelvin connections effectively eliminate measurement errors caused by cable resistance, while guard connections help reduce leakage current, yielding more reliable results for extremely low current measurements.

The GX3104's powerful capabilities are complemented by comprehensive software support. Marvin Test Solutions provides a full-featured API (Application Programming Interface) and user interface (UI) for the module. The GXSMU software library includes virtual instrument panels, allowing users to intuitively control and monitor instrument status through a graphical interface. It also offers Windows 32/64-bit DLL driver libraries with detailed documentation for easy integration into various automated test systems.

To accommodate different development environments, the GX3104 supports multiple mainstream programming tools and languages, including ATEasy®, LabVIEW, LabVIEW/Real-Time, C/C++, Microsoft Visual Basic®, Delphi, and Pascal. Through provided interface files, developers can seamlessly integrate the GX3104 into existing test platforms.

For Linux users, Marvin Test Solutions offers the GtLinux software package, ensuring compatibility across different operating systems. Comprehensive online help files and PDF user guides provide complete guidance from installation to programming.
