Like all Series 2400 SourceMeter models, the Model 2401 provides precision voltage and current sourcing and measurement capabilities (1μV–20V and 10pA–1A). It is both a highly stable DC power source and a true instrument-grade 5½-digit multimeter. The power source characteristics include low noise, precision, and readback. The multimeter capabilities include high repeatability and low noise. The result is a compact, single-channel, DC parametric tester. In operation, it can act as a voltage source, a current source, a voltage meter, a current meter, and an ohmmeter. The Lowest Cost Precision SMU (source measurement unit) on the Market The Model 2401 is the lowest cost precision SMU instrument on the market, offering an economical 20W I-V source/measure alternative to configuring systems and test benches with separate programmable power supplies and digital multimeters. The Model 2401 also offers an economical alternative for applications for which precision programmable power supplies cannot deliver sufficient accuracy, signal range, source setting, or readback resolution. The Model 2401 offers users all the same accuracy, speed, and measurement functions as the rest of the instruments in the Series 2400 family. It shares a common operating code base with the rest of the family, so it can be operated and programmed within its range boundaries just like any other Series 2400 instrument. The only functional differences between the Model 2401 and the Model 2400 are that the Model 2401 does not include 200V source and measure ranges or back panel Digital I/O port capabilities. (However, the DB-9 connector is still provided to provide test fixture interlock signals.) Model 2401 Applications Manufacturers of components and modules for the communications, semiconductor, computer, automotive, and medical industries will find the Model 2401 invaluable for a wide range of characterization and production test applications. The Model 2401 is well suited for use as a gate bias in applications involving devices with three or more terminals such as HBLEDs and photovoltaic cells, reducing total system hardware costs. It also provides sufficient range for characterizing low voltage materials and devices (including graphene and other nano- and MEMs-type structures), which are inherently low voltage oriented.
