NetDAS/Ubuntu Linux – 24-bit TCP/IP Data Acquisition Recorder

NetDAS Ubuntu Linux 24-bit Data Recorder
24-bit NetDAS Ubuntu Linux Data Acquisition
DAQ Systems’ 24-bit data acquisition systems support seismic earthquake recording and sensor digitization logging under Ubuntu Linux. Data is GPS time-stamped in six formats and presented graphically in real-time and available with client/server Internet connectivity. The 24-bit USB analog-digital converter runs standalone with a Java data acquisition app. The client/server suite includes 24-bit data server, event triggering and recording, format conversion, real-time display, data stream concentration via a software hub and a state-of-the art GPS data time stamp. NetDAS Ubuntu Linux supports 4 to 16 channels at 24-bit resolution.
