NI national instruments recently launched NI PXIe - 4135 power measurement unit (SMU) with 10 fa measurement sensitivity and up to 200 v voltage output.

Through the NI PXI SMU flexible elasticity, high channel number density, excellent test output rate, engineers can use NI PXIe - 4135 SMU measure low current signal, and perform the wafer parameters testing, materials research, low electricity flu a variety of applications such as sensors and the characteristics of IC test.

Engineers can through modularization NI PXI SMU building volume is exquisite, the number of multichannel parallel system, and have as many as 68 SMU channel single PXI chassis, wafer can be executed for hundreds of channel stability testing and parallel testing.

In addition, users can make use of high-speed communications bus, precise hardware series, technology and digital control circuit, thereby improve the test output rate and custom fine-tune any SMU response of the device under test. Users can also use the software control SMU response, not only can shorten the SMU stabilizing the waiting time of operation, can also by elastic reduce overshoot and oscillation of the software, even the same high capacitive load.

NI PXI SMU use interactive software human-machine interface to perform basic measurement and automation applications debugging, its operation easy degree is box type SMU cannot achieve. This driver provides examples of auxiliary files, documents and immediately available programs, in order to assist the development of testing code, it also provides the programming interface, can match. C, Microsoft.net development environment with LabVIEW software system design, etc.

Engineers can also use NI NI PXI SMU collocation TestStand test management software, thereby simplifying test system in the laboratory and the production line build and deployment.
