The PXIE-6556 is a 200 MHz digital waveform generator/analyzer with PPMU (Four-quadrant Unit Pin Parameter Measurement Unit) function. Used primarily for validation or production testing, it is the most comprehensive and flexible of NI (National Instruments) high-speed digital I/O modules.
The device features 24 high-speed dynamic data channels, each equipped with PPMU capabilities to generate or capture digital data, as well as dynamic DC parameter measurements. Each channel has a programmable voltage level range of -2.0 to 7.0 V, including VOH, VOL, VTT, VIH, and VIL, and can output up to 32 mA of independent source or drain current.
The PXIE-6556 is also equipped with a precision timing engine with a subhertz frequency and a timing resolution of 30 ps per pin, providing a high degree of measurement and control accuracy. In addition, it has advanced ATE (Automatic test equipment) capabilities, including active loads, small inter-channel latency, and external SMU (source measurement unit) integration, making it excellent in a variety of test applications.
The main application scenarios of this device include but are not limited to industrial automation, test and measurement, and scientific research experiments. For example, engineers can use the PXIE-6556 to generate digital waveshapes up to 200 MHz or perform DC parameter measurements on the same pin, simplifying wiring, reducing test time, and increasing the measurement density of DC parameter testers. At the same time, its high precision and high-speed sampling rate also enable it to capture important transient characteristics of equipment, providing strong support for scientific research and test work.
Overall, the PXIE-6556 is a powerful, high-performance digital waveform generator/analyzer for a wide range of applications requiring high precision measurement and control.
