Next Generation Qualification: Quanterra Q330HR Digitizer Evaluation
Sandia National Laboratories has tested and evaluated a new digitizer, the Q330HR , manufactured by Quanterra . These digitizers are used to record sensor output for seismic and infrasound monitoring applications. The purpose of the digitizer evaluation wa s to measure the performance characteristics in such areas as power consumption, input impedance, sensitivity, full scale, self - noise, dynamic range, system noise, r esponse, passband, and timing. The Q330HR is Quanterra ' s improved Q330 datalogger with a 2 6 bit s of resolution on channels 1 - 3 and a 24 bits of resolution on channels 4 - 6 (26 bit is optional ). The Quanterra Q330HR is being evaluated for potential use U.S. Air Force seismic monitoring systems as part of their Next Generation Qualification effort .
