|
|
- System design allows for fast and accurate field measurements
|
|
|
|
|
|
- System includes a 12-channel geophone (4.5 Hz) string with ~ 10 ft (~ 3 m) spacings and a 100 ft (~ 30 m) extension cable for flexible testing setups
|
|
|
|
|
|
- The National Instruments 16 bit A/D data acquisition card with a maximum sampling rate of 64,000 samples/second for 13 channels allows for user programmable gain from x1 to x10,000 on the channels which makes the sensitivity equivalent to a 24 bit seismic system
|
|
|
|
|
|
- Data is acquired by triggering off of a single 4.5 Hz trigger geophone spiked in the ground by the impact point to record the source impact (sledgehammer, shotgun or other impact source not included)
|
|
|
|
|
|
- Real-time waveform display while testing
|
|
|
|
|
|
- Data is exported in SEG2 format which allows for analysis with both IXRefrax® and Reflexw® optional software packages, as well 3rd party seismic data analysis programs
|
|
|
|
|
|
- System is compact, durable, and easily transported, allowing for multiple
tests per day
|
|
|
|
|
|
- Available as an add-on to the Freedom Data PC platform (required,
sold separately).
