National Instruments 778994-01 PXI Digital Waveform Instrument

The part number 778994-01 from National Instruments is the identifying part number for the PXI-6562 PXI Digital Waveform Instrument. This module features 16 data channels having a maximum sampling rate of 200 MHz providing high precision and flexibility in various testing and measurement applications. This digital waveform instrument offers three onboard memory sizes that are 2 Mbit. 16 Mbit and 128 Mbit per channel providing enough space for waveform storage. This module supports both the acquisition and generation of waveforms, with channels supporting Single Data Rate (SDR) and Double Data Rate (DDR) modes. This flexibility is critical for applications that demand high-speed data transfer and accurate timing synchronization. 

The 778994-01 PXI Digital Waveform Instrument is designed to consume the power of a minimum 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 total power requirement of 16.4 W, maximum. Its dimensions are 21.6 cm × 2.0 cm × 13.0 cm and weighs 340 g (12.0 oz). It is equipped with an SMB jack I/O connector for the external sample clock, triggers, and exported sample clock.

This module is designed to operate at an ambient temperature of 0 degrees Celsius to 55 degrees Celsius with an operating relative humidity of 10% to 90%, noncondensing and storage temperature of -20 degrees Celsius to 70 degrees Celsius with a relative humidity of 5% to 95%, noncondensing. Its operating shock is 30 g, half-sine, 11 ms pulse (meets IEC 60068-2-27) standard and its operating vibrations are 5 Hz to 500 Hz, 0.31 grms (meets IEC 60068-2-64) standard with its storage shocks of 50 g, half-sine, 11 ms pulse (meets IEC 60068-2-27) and storage vibrations of 5 Hz to 500 Hz, 2.46 grms (meets IEC 60068-2-64). 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 is fully compliant with many safety and electromagnetic standards thus making it useful for measurement, control, and laboratory use as well as limiting electrical interference thus maintaining the efficiency of the module. It supports software such as LabVIEW, LabWindows™/CVI™, Measurement Studio, Microsoft Visual C/C++, and NET (C# and VB.NET).
