National Instruments 778989-01 Digital Waveform Device.

The part number 778989-01 from National Instruments is the identifying part number for the PCI-6542 Digital Waveform Device. This PCI device features 32 data channels supporting both the acquisition and generation of waveforms, with 4 Programmable Function Interface (PFI) channels. This flexibility is critical for applications that demand high-speed data transfers and accurate timing synchronization. For data acquisition channels, it features single-ended data channels with a programmable function interface (PFI), specifically PFI <0..3>. Its output impedance is 50 Ω with an output protection range of 0 V to 5 V. For the generation channels, it offers DDC CLK OUT and PFI channels for precise timing control and flexible signal management, crucial for complex data acquisition and generation tasks. Its input impedance is 50 kΩ and has a voltage input protection rating of -1 V to 6 V.
 
The 778989-01 Digital Waveform Device is designed to operate at a typical of 1.6 A at +3.3 VDC, 1.2 A at +5 VDC, 0.25 A at +12 VDC, and 0.06 A at -12 VDC, with a maximum total power requirement of 20.5 W. Its physical dimensions are 12.6 cm × 35.5 cm, and it weighs 410 g (14.5 oz). It is also equipped with an SMB jack I/O connector for an external sample clock, triggers, an exported sample clock, and a 68-pin VHDCI connector for digital data channels, exported Sample clock. 

It is designed to operate at an ambient temperature of 0 degrees Celsius to 45 degrees Celsius with a relative operating humidity of 10% to 90%, noncondensing, that meets the IEC 60068-2-56 standard, and a suitable storage temperature of -20 degrees Celsius to 70 degrees Celsius that meets the IEC 60068-2-2 standard with a relative storage humidity of 5% to 95%, noncondensing. It can be mounted at an altitude of 2000 meters above sea level, at a maximum temperature of 25 degrees Celsius, and has a pollution degree of 2

The 778989-01is fully compliant with many safety and electromagnetic standards, thus making it useful for measurement, control, and laboratory use, as well as limiting electrical interference and thus maintaining the efficiency of the module. It supports application software such as LabVIEW, Lab Windows™/CVI™, Measurement Studio, Microsoft Visual C/C++, and NET (C# and VB.NET).
