- Аннотация: The MSR-AE-21 high-speed multichannel system for recording AE signals was developed, basedon modern E20-10 four-channel 14-bit ADCs, produced by the Russian company LCard. The system isdesigned for continuous and synchronous recording of the acoustic emission (AE) stream from 21 piezoelectricsensors and is used as part of a laboratory hardware–software system for testing rocks under uniaxial andtriaxial strain conditions. A digitization frequency of up to 7.5 MHz per channel makes it possible to analyzein detail AE signals with a frequency of up to 750 kHz. The 40 dB preamplifier block has a bandwidth from1.5 to 750 kHz. Continuous recording over all channels during the entire test time makes it possible at the endof recording to search for and identify acoustic events in a wide dynamic range of amplitudes and energieswith minimal loss/omission of individual AE events. The use of fast information processing algorithms makesit possible to recognize events in real time, detecting and discarding intervals with no signals and therebyreducing the total amount of information recorded in the database.
