The GEOthree series high resolution 3+1 analog seismic channels telemetry digitizer / recorder.
The size of the instrument is only 168 X 106 X 68mm. The power consumption is only 0.9W for 3 channels.
Available sampling rate is 100 to 1000sps and optional lower sampling rates are supported. Built in GPS receiver combined with ultra accurate DPLL unit providing time drift 10e-9 sec ensures timing stability even in the absence of GPS signal. NTP timing is also available. The unit is very flexible and accepts several types of analog front end units so any type of seismic sensor can be connected. Additionally it provides eight extra low resolution and rate analog inputs for seismometer mass position monitoring, or any other environmental parameter monitoring.
Eight TTL command outputs are supported for seismometer control or for any other external device control. Typically the digitizer supports differential variable gain preamplifier. Our force-balance sensor front end is also supported, providing a wide-band response (10sec – 98Hz) and high sensitivity 1500V/m/s by connecting a C100 sensor. Acquisition parameters and operation modes can be set from the user – friendly web interface.
