Specific features

• Synchronous multichannel (up to 3) recording for any low voltage signal.
• Recording parameters are set up using push buttons. No need to connect to an external computer.
• Independent & portable device with a powerful internal battery & a removal SD Card for efficient data storage.
• Accuracy high quality system for ambient vibration recordings, to synchronously record one sensor, 3 channels.
• May be used with passive or active sensors. Active sensors are powered by MiniShark through the same cable used for recording the signal.
• Very low internal noise allowing the use of a 4.5Hz sensor to study frequencies down to 0.2 Hz.
• The internal GPS, a high quality clock and continuous recording allow MiniShark to be used for earthquake recording.
• Continuous recording.
• Possible external power (through a battery or the charger) for long-term experiments.
• Statistical tests, used to evaluate gain variations, offsets, absence of missing code, internal noise level, remote triggering and synchronism between channels proved MiniShark to be a very reliable data acquisition system.
• The data software package: Geopsy open source software, and available at geopsy.org for free, makes it possible to format the flash card and retrieve data in ASCII spreadsheet-ready format, in an easy and time-effective way producing very easy to handle data files, or directly in SAC format.
• The software runs under the most common systems (MS-Windows, Linux, Mac OSX).
• Finally, while mostly used in the framework of ambient vibration studies, MiniShark can handle any kind of low voltage signal.
