Recording Truck
The mobile control room of the seismic crew, where the signals from the receivers are recorded.
What it does
The recording system amplifies, filters and digitizes the signals. In telemetry systems, station boxes near the receivers do this and send the data by wire, optical fiber or radio, avoiding signal loss and noise on long cables.
Basics
| Does | Amplify, filter, digitize, record |
| Set by crew | Sample rate, record length, filters |
| Telemetry | Wire, optical fiber or radio |
Common failures
- Noise picked up on long analog cables
Troubleshooting
- Symptom
- Noisy traces, for example 60 Hz power line noise
- Likely cause
- Long hard wired cables
- What to check
- Digitize near the receivers with a telemetry system
