National Instruments 788511-01 Sound and Vibration Module
The National Instruments 788511-01 is a Sound and Vibration Module. It is also known as the PXIe-4468 unit and is designed for precision measurements in sound and vibration applications. The module features 2 x simultaneously sampled input channels that supports differential or pseudodifferential configurations along with software-selectable AC/DC coupling. This NI 788511-01 unit utilizes a 24-bit delta-sigma ADC with a sampling rate range from 100 S/s to 250 kS/s. The module is equipped with 6 x gain settings that allow users to configure input ranges to suit specific measurement needs along with a maximum overvoltage protection of ±42.4 V peak.
The output characteristics of the 788511-01 include 2 x analog output channels that are also simultaneously sampled. These channels can be configured as differential or pseudodifferential along with a DC coupling and 24-bit delta-sigma DACs. The output channels support sample rates from 100 S/s to 200 kS/s and offer software-selectable attenuation. The 788511-01 module also supports a FIFO buffer size of 1,023 samples for both input and output channels that facilitate efficient data transfer through direct memory access (DMA) or programmed I/O.
The NI 788511-01 offers various input amplifier characteristics, such as high input impedance and common-mode rejection ratio (CMRR) that ensure reliable signal integrity. The alias-free bandwidth extends to 101.536 kHz along with an alias rejection of 105 dBc. The module also supports Transducer Electronic Data Sheet (TEDS) according to the IEEE 1451 Standard along with maximum load capacitance of 10,000 pF. The 788511-01 includes both analog and digital triggering capabilities that allows for precise event detection and synchronization across multiple channels. The module is compatible with various PXI Express and hybrid slots while featuring a compact 3U form factor.
The dimensions of the module are 16 cm x 10 cm (6.3 in. x 3.9 in.), not including the dimensions of connectors. The overall weight of the module is 360 g (12.7 oz.). The unit is designed to operate under the temperature range of 0 °C to 55 °C. The maximum allowable installation altitude for this module is 2000 meters above sea level. The NI 788511-01 unit is ideal for applications such as audio testing, automotive noise and vibration analysis, and machine condition monitoring.
