We use an Elsys TraNET EPC computer for data acquisition and storage. The Elsys TraNET EPC performs the acquisition of raw, unfiltered data from 15 Panametrics p- and s-wave transducers at 0.5-50 MHz, and a 20-channel Acoustic Emission (AE) amplifier filters and boosts small signals from sensors.

A Tabor WW5064 arbitrary waveform generator combined with a 9400 400 Vpp high voltage amplifier is configured to provide input signals for data acquisition in active/controlled source mode.

A National Instruments NI-cDAQ containing 12 channels for strain input and 32 differential or 64 single-ended channels for analog voltage input, connected to the TraNET EPC, is configured to sample, record, and save strain and voltage inputs at 10 kHz.
