Welcome To Seismic Source Company

Seismic Source Company is a manufacturer of seismic instruments and data acquisition systems. Its products are used in a broad range of applications: Seismology, Structural Monitoring, Seismic Site Evaluation, Civil Engineering, Gas and Oil Exploration, Industrial Vibration Monitoring.


DAQ Link II System
For use with any seismic recorder

VSSS is used with Vibrator Control Electronics (VCE) for vibrator quality control. VSSS transforms VCE Reference Signal, output signals of accelerometers, calculated Ground Force signal into low-level differential signals suitable for a seismic data acquisition system.

  • Allows Wireline Similarity for any Vibrator Electronics.
  • Wireline Similarities use True Reference (Pilot) signal for Analysis. Prevents confusion of switching Seismic Recorder to “Wireline Reference”.
  • VSR - Vibrator Signature Recording - Allows Seismic Recorders to Record Vibrator Signature.

Three main channels: True Reference, Reaction Mass Sim Accelerometer, and Baseplate Sim Accelerometer

Two additional channels: external Reaction Mass Sim Accelerometer and external Baseplate Sim Accelerometer
