The National Instruments 778993-01 is a PXI-6561 PXI Digital Waveform Instrument designed for high-performance digital signal testing and data acquisition. As part of the PXI Express (PXIe) platform, this module delivers exceptional bandwidth and low latency, making it ideal for applications that require precise timing and synchronization. With 16 data channels, the 778993-01 enhances data acquisition efficiency, reducing the need for multiple devices in data processing workflows. It operates in both double data rate (DDR) mode, which allows data transfer on both the rising and falling edges of the clock signal, and single data rate (SDR) mode, transferring data solely on the rising edge. This versatility makes the instrument suitable for a variety of applications, including semiconductor device testing.

The module offers extensive triggering and event capabilities, enabling precise test execution control. Users can configure triggers for start, pause, script execution, and other events, allowing for flexible routing to different channels or external devices. Additionally, programmable function interface (PFI) channels enhance the module's signal routing and control flexibility.

The PXI-6561 operates with a maximum power consumption of 16.4 W and is designed for an ambient temperature range of 0 to 55 degrees Celsius. Its storage temperature range is -20 to 70 degrees Celsius, with a relative humidity tolerance of 10% to 90% (non-condensing) during operation and 5% to 95% (non-condensing) during storage. The instrument complies with IEC 61010-1, EN 61010-1, UL 3111-1, and UL 61010B-1 standards, ensuring safety for use in measurement, control, and laboratory environments. However, it does not have an ingress protection rating, so it should be kept away from dust and moisture.

For software integration, the 778993-01 is compatible with NI-HSDIO driver software, providing a comprehensive API for module configuration and control. It supports various software environments including NI LabVIEW, Lab Windows/CVI, and .NET, facilitating easy incorporation into automated testing systems.
