3D LAND GEOPHONE WITH USB INTERFACE MOD. GEMINI-2 & GEMINI-4 Gemini-2 & Gemini-4 represent PASI answer to the increasing request for HVSR acquisition: a single waterproof case with integrated a low frequency, high performing 3D-geophone assembly (two versions available, with real 2Hz or 4.5 Hz sensors properly coupled) and a powerful true 24 bit data acquisition board. Through Gemini USB interface and the related data acquisition software your PC will be transformed in a perfect, very high performing instrument for both data recording and post-processing analysis. Data acquisition board speifications Power supply: through USB port Sampling rate: from 20Hz to 8000 Hz A/D Sigma-Delta converter resolution: 24 real Bit Record time: up to 120min (std.ver.) Acquisition channels: No. 3 S/N ratio at fs=1KHz: 117 dB S/N ratio at fs=8KHz: 109 dB Passband at fs=1KHz: 110 Hz, proportional to sampling rate Nat.
