National Instruments 779068-01 Multifunction I/O Device 

National Instruments part number 779068-01 is an identifying part number for the PCI-6229, a Multifunction I/O Device. The NI 779068-01 is a 32 Analog Input (16-bit, 250 kS/s), 4 Analog Output, 48 Digital Input/Outputs PCI Device. It provides analog I/O, correlated digital I/O, two 32-bit counters/timers, and digital triggering. 

This device offers low-cost, reliable data acquisition for various applications, including laboratory automation, research, design verification/testing, and manufacturing testing. Signal conditioning modules such as SCC or SCXI can be used to enhance sensor and high-voltage measurement capabilities. The 779068-01 comes with versatile analog input capabilities with 16 channels in differential mode or 32 channels in single-ended mode, adaptive for various measurement setups. With a 16-bit ADC resolution, it ensures accurate data acquisition. 

The maximum sampling rate for multichannel operation, when aggregating data, reaches 250 kS/s, enabling efficient data collection. This DAQ device is recognized for its efficient channel setup, featuring four analog output channels. It achieves a maximum update rate of 833 kS/s with one channel operational. When using two, three, and four channels simultaneously, users can achieve update rates of 740 kS/s, 666 kS/s, and 625 kS/s per channel respectively. The analog outputs of the 779068-01provide a ±10 V output range, precise 50 ns timing resolution, low 0.2 Ω output impedance, and support DC output coupling.

Data transfers are facilitated through DMA (scatter-gather), interrupts, and programmed I/O for PCI connectivity, while USB connectivity utilizes USB Signal Stream and programmed I/O methods to ensure efficient data communication for different system configurations.
