National Instruments 778999-01 PXI Analog Output Module .
The part number 778999-01 from National Instruments is the identifying part number for the PXI-6722 PXI Analog Output Module. This module features 8 voltage output channels, which allows it to be used for multiple operations making it ideal for use in signal generation, control systems and automated testing. This 778999-01 module has double-buffered digital-to-analog converter (DAC) meant to provide smooth and continuous output. It is possible to update up to 476 kS/s with a local FIFO and up to 182 kS/s using host PC memory. This ensures high-speed data transfer when working with dynamic applications. The 2047 sample FIFO buffer available in this module improves its ability to handle large datasets without losing any information.
This module consist of 3 DMA channels and variety data transfer methods such as DMA, interrupts, and programmed I/O that are aimed at enhancing smooth handling of data. Additionally, the scatter-gather DMA mode optimizes the process of transferring data further. To achieve accurate and consistent voltage delivery, +10 V voltage output range combined with DC output coupling and low output impedance of 0.1 Ω is used. For example, the 778999-01 can drive a maximum current of +5 mA while still maintaining its output stability even on any passive load. Some protective features such as short-circuit to ground have been incorporated to prevent possible harm.
This PXI module supports digital trigger from PXI trigger lines <0..5> with a 10 ns minimum pulse width that is compatible with 5 V TTL. This module has a power consumption of +3.3 VDC at 300 mA while +5 VDC at .1.5 A typical, 3 A maximum. It has a physical dimensions of 16 cm × 10 cm (6.3 in. × 3.9 in.) with an I/O connector of 1 68-pin VHDCI.
The is designed to operate at an ambient temperature of 0 degrees Celsius to 55 degrees Celsius and storage temperature of -20 degrees Celsius to 70 degrees Celsius with humidity level ranging from 5% to 90% RH, noncondensing. It is designed to be mounted at an maximum altitude of 2000 meters with a pollution degree of 2.
