GSB Data Recorder with Internal Battery
The GSB is a self-contained, autonomous data recorder. A battery, charger, 24-bit digitizer, GPS and GLONASS receiver are enclosed in its sealed case. A built-in test signal generator and up to 32 GB of non-volatile, solid-state data storage allow for quality and reliable data. Although the GSB contains an internal battery for 24 hour a day for 60 days operation, an external battery can be connected to extend operational time.
