National Instruments 778279-03 PXI Sound and Vibration Module
The 778279-03 is a crucial component of the PXI-4472B model, designed and manufactured by National Instruments. This advanced module is tailored for sound and vibration measurements, featuring eight analog input channels with 24-bit resolution and AC/DC coupling. It offers a maximum sampling rate of 102.4 kS/s and a 0.5 Hz cutoff frequency, utilizing delta-sigma modulation for an extensive dynamic range.
Because of its analog trigger circuitry, the 778279-03 can precisely track individual input channels and provides multiple trigger options, such as window, analog edge, and analog edge with hysteresis. For full DMA bus-master data transmission rates of 20 to 30 MB/s, it uses PCI mini-MITE, which guarantees effective data handling. Furthermore, data loss during extended DMA or interrupt service latency is avoided using a 1,024-sample analog input FIFO.
The module offers a smooth hardware and operating system interface through its interaction with NI-DAQmx. This makes it easier to integrate the 778279-03 with other pieces of gear and software, including multifunction DAQ products, in order to create automated testing systems or carry out intricate measurements.
The 778279-03 finds use in a variety of sectors with applications in vibration analysis and audio. It works especially well for applications like order spectra, order maps, order extraction, sound level measurements, frequency response analysis, fractional octave analysis, and power spectra production.
Multiple 778279-03 modules can be synchronized using the PXI star trigger bus for scenarios that demand high channel counts. As a result, devices in the same chassis can synchronize within 1 ns due to precise timing signals across modules that have little skew.
The 778279-03 module's key features include inbuilt antialiasing filters that automatically adjust to the sample rate and integrated electronic piezoelectric (IEPE) signal conditioning for accelerometers and microphones. The trigger modes supported by the module include posttrigger mode, which digitizes signals after a trigger condition occurs, and pretrigger mode, which digitizes signals both before and after a trigger condition.
