Shear-wave vibrator Easy handling also in rough terrain.
Wheelbarrow technique Very easy access of vibrator points using a wheelbarrow. The box obove the source contains the 12 V or 24 V DC power supply. The control system is attached to the source.
Signal generator Programmable signal generator with high-quality 16 Bit AD converter in order to generate the analog sweep signal as well as the trigger signal for the recording unit. A +/- switch allows to invert the sweep direction with respect to wave-field separation. Sweep duration and frequency range are variabel and can be individually set by means of an E-prom.
Vibration attenuation Shoc adsorbers attenuate the vibrations between source and wheelbarrow with power supply unit. The shoc adsorbers are controlled by a pressure gauge and can be individually inflated by an air pump.
Signal controle Trigger signal output voltage: 0.1 Vpp Sweep signal output voltage: 20 Vp
Power Supply Vibrator: lead-acid battery, 2x 12 V/ 90 Ah Control unit, source ventilation: 12 V/ 17 Ah
