National Instruments 778994-01

The National Instruments part number 778994-01 refers to the PXI-6562 PXI Digital Waveform Instrument, designed for high-performance testing and measurement applications. This module features 16 data channels and achieves a maximum sampling rate of 200 MHz, delivering exceptional precision and flexibility. It offers three onboard memory configurations per channel—2 Mbit, 16 Mbit, and 128 Mbit—allowing for substantial waveform storage capacity. The device supports both waveform acquisition and generation, operating in Single Data Rate (SDR) and Double Data Rate (DDR) modes, which is essential for high-speed data transfer and accurate timing synchronization.

The PXI-6562 operates with a minimum power requirement of 1.8 A at +3.3 VDC, 1.0 A at +5 VDC, 0.4 A at +12 VDC, and 0.05 A at -12 VDC, with a maximum total power consumption of 16.4 W. It is designed within compact dimensions of 21.6 cm x 2.0 cm x 13.0 cm and weighs 340 g (12.0 oz). For connectivity, the module is equipped with an SMB jack I/O connector to facilitate external sample clocks and triggering.

Operating temperature ranges from 0 °C to 55 °C with a relative humidity of 10% to 90% (non-condensing), while it can withstand storage temperatures between -20 °C to 70 °C and a relative humidity of 5% to 95% (non-condensing). The module meets rigorous standards for operational shock (30 g, half-sine, 11 ms pulse) and vibration (5 Hz to 500 Hz, 0.31 grms), ensuring reliability in demanding environments. Additional features include compliance with safety and electromagnetic standards, making it suited for measurement, control, and laboratory applications while minimizing electrical interference. The PXI-6562 is compatible with various software platforms, including LabVIEW, LabWindows™/CVI™, Measurement Studio, Microsoft Visual C/C++, and .NET (C# and VB.NET).
