#Data Translation's ARM-Based Dynamic Signal Analyzer Module for Noise and Vibration Measurement To assist OEM users complete source code is provided that can be modified and used without any restrictions. Further examples show how to develop an embedded application for any specific purpose using various open-source libraries and utilities. Vibration testing has increased dramatically driven by the strong sales of consumer products such as cell phones tablets performance cameras so that every product must undergo strict vibration testing, states Fred Molinari President. With the embedded Beaglebone Black industrialized ARM processor real-time processing and analysis for vibration testing is simplified greatly. The highly accurate front-end design of the DT7837 allows simultaneous measurement of four 24-bit IEPE sensor inputs at a sampling rate of 102.4 ks/s. The module is ideal for precision measurements with microphones accelerometers and other transducers that have a large dynamic range. Common applications include audio acoustic and vibration testing. Additionally the DT7837 is equipped fully to do many vibration tasks by including a 24-bit stimulus output tachometer general-purpose Digital I/O external trigger functions and counter/timers. These functions are supported by a complete set of well-documented APIS that enable development of an embedded application using the AD DA counter timers tachometer and other onboard I/O. The ARM block processor is the TI AM335X ARM Cortex-A8 including BBB functions FPGA memory and support peripherals as well as interfaces for a USB host and client Ethernet power and SD card. The module is ideal running open-source Linux using the TI AM335X SDK Essentials Version 7. 0. The DT7837 runs Linux 3. 12 with customer loadable kernel modules LKM to expose the onboard hardware to Linux user space applications via virtual file interfaces s
