PXIE-6556 数字波形仪

PXIE-6556是一款由美国国家仪器（National Instruments，简称NI）制造的200 MHz高速数字I/O模块，具有四象限单位引脚参数测量单元（PPMU）功能。这款设备专为验证或生产测试而设计，是一款最全面、最灵活的NI高速数字I/O模块。

PXIE-6556模块具有24路高速动态数据通道和4路控制通道，每路通道都具有PPMU功能。这意味着每个通道都可以独立进行电压等级、定时偏移和参数测量调整，从而提供精确和灵活的测试能力。此外，每个引脚的可编程电压电平范围在-2.0到7.0 V之间，包括VOH、VOL、VTT、VIH和VIL等，使得模块能够适应多种测试需求。

在性能上，PXIE-6556的每通道可高达32 mA的独立源极或漏极电流，为测试提供了强大的电流支持。其精密的定时引擎具有亚赫兹频率和每个引脚30 ps的定时分辨率，为测试提供了高精度的定时能力。同时，其高级ATE功能包括有源负载、较小的通道间延迟和外部SMU集成，进一步提升了测试的效率和准确性。

PXIE-6556的应用场景非常广泛。工程师们可以利用其高达200 MHz的采样率，产生和获取数字波形，或在同一针脚上以1%的误差率执行DC参数测量，从而简化布线，减少测试时间，并提高直流参数测试仪的测量密度。此外，其内置的时序校准功能可以自动调整时序，消除不同连线与线路长度所造成的时序偏移，提高测试的准确性和稳定性。

总的来说，PXIE-6556是一款功能强大、性能卓越的200 MHz高速数字I/O模块，具有PPMU功能，能够满足各种复杂的测试需求。无论是验证、生产测试，还是其他需要精确数字I/O和参数测量的应用，PXIE-6556都能提供出色的解决方案。

The PXIE-6556 is a 200 MHz high-speed digital I/O module manufactured by National Instruments (NI) with a four-quadrant unit Pin Parameter Measurement Unit (PPMU) function. Designed for validation or production testing, this device is the most comprehensive and flexible NI high-speed digital I/O module available.

The PXIE-6556 module has 24 high-speed dynamic data channels and 4 control channels, each of which has PPMU function. This means that each channel can be independently adjusted for voltage levels, timing offsets and parameter measurements, providing accurate and flexible testing capabilities. In addition, the programmable voltage levels of each pin range from -2.0 to 7.0V, including VOH, VOL, VTT, VIH, and VIL, making the module adaptable to a variety of test requirements.

In terms of performance, the PXIE-6556’s independent source or drain current of up to 32 mA per channel provides strong current support for testing. Its sophisticated timing engine has a subhertz frequency and a timing resolution of 30 ps per pin, providing high-precision timing capabilities for testing. At the same time, its advanced ATE features include active loads, small inter-channel latency, and external SMU integration, further improving the efficiency and accuracy of testing.

The PXIE-6556 is used in a wide range of applications. Engineers can take advantage of its sampling rate of up to 200 MHz, generate and acquire digital waveshapes, or perform DC parameter measurements with a 1% error rate on the same pin, simplifying wiring, reducing test time, and increasing the measurement density of DC parameter testers. In addition, its built-in timing calibration function can automatically adjust the timing, eliminate the timing offset caused by different wire and line length, improve the accuracy and stability of the test.

Overall, the PXIE-6556 is a powerful, high-performance 200 MHz high-speed digital I/O module with PPMU capabilities to meet a variety of complex test needs. Whether it’s verification, production testing, or other applications that require accurate digital I/O and parameter measurement, the PXY-6556 provides the perfect solution.
