The National Instruments part number 778953-01 corresponds to the PXI-6542 PXI Digital Waveform Instrument, a high-performance module designed for the PXI Express (PXIe) platform. This instrument is engineered for applications that demand high bandwidth and low latency, making it ideal for precise timing and synchronization tasks. The PXI-6542 features 32 data channels that facilitate efficient data acquisition, thus reducing the need for multiple devices in data processing workflows. It can operate in either double data rate (DDR) mode, allowing data transfer on both the rising and falling edges of the clock signal, or in single data rate (SDR) mode, which transfers data solely on the rising edge.

This instrument supports a variety of triggering and event capabilities, providing precise control over test execution with configurable triggers for start, pause, and script events, as well as external device routing. Additionally, it includes four programmable function interface (PFI) channels, ensuring enhanced flexibility in signal routing and control. The PXI-6542 is compatible with NI-HSDIO driver software and is best utilized with various programming environments, including LabVIEW, LabWindows/CVI, and .NET.

With a typical power consumption of 15 W and a maximum consumption of 20.5 W, the module operates effectively within an ambient temperature range of 0 to 55 degrees Celsius. It is also designed to endure storage temperatures from -20 to 70 degrees Celsius, with a relative humidity tolerance of 10% to 90% non-condensing in operation and 5% to 95% non-condensing during storage. The PXI-6542 complies with IEC 61010-1, EN 61010-1, UL 3111-1, and UL 61010B-1 standards, ensuring its suitability for electrical measurement, control, and laboratory applications. Note that this model does not have an ingress protection rating and should not be used in environments where dust and moisture may be present.
