<p>A system for testing seismic signal recording equipment wherein a test signal is generated which simulates the output of at least one seismic sensing device, and, thereafter, the test signal is applied to the seismic signal recording equipment. The test signal is recorded by the seismic signal recording equipment and the recorded signal is compared with the generated test signal to evaluate the performance characteristics of the seismic signal recording equipment. The system can include circuitry to vary component elements of the test signal to test different performance characteristics of the seismic signal recording equipment, as well as ability to generate a random noise signal for addition to the test signal.</p> |
