NI Modules expands PXI Platform Capability

National instrument (NI) has expanded the capabilities of its PXI platform for semiconductor characterization and production test with new per-pin parametric measurement unit (PPMU) modules and source measure unit (SMU) modules. The NI PXIe-6556 200 MHz high-speed digital I/O with PPMU, the NI PXIe-4140 and NI PXIe-4141 four-channel SMUs reduce the cost of capital equipment, decrease test times and increase mixed-signal flexibility for a variety of devices under test.

With the NI PXIe-6556 high-speed digital I/O module, engineers can generate and acquire a digital waveform at up to 200 MHz or perform DC parametric measurements with one percent accuracy on the same pin, simplifying cabling, decreasing test times and increasing the density of the tester. In addition, engineers can nearly eliminate timing skew due to different cable and trace lengths to the device under test with the built-in timing calibration feature that automatically adjusts timing for these differences. The NI PXIe-6556 comes with an option to switch in another NI SMU for higher precision, and engineers can trigger parametric measurements based on hardware or software triggers.

The NI PXIe-4140/41 SMU modules provide four SMU channels per PXI Express slot and up to 68 SMU channels per PXI chassis in 4U of rack height to simplify testing of high-pin-count devices. With sampling rates of up to 600,000 samples per second, engineers can drastically reduce measurement times or capture important transient characteristics of the device.
