The vibrator source ElViS VII is used to generate P- or S-wave sweep signals. The source consists of a moving mass driven by a cascaded linear motor. The source is fully cased. An adjustable pneumatic suspension ensures a maximum release of seismic energy under different surface conditions. The source is most suitable for refection seismic surveys on paved roads and for urban areas. A wheelbarrow allows the movement of the source along the seismic line.
