Topside Provided Isolation
The two most common sources of noise are power supplies and poor grounding on survey
vessels. Edgetech’s proprietary signal conditioning and isolation board is shipped with every topside to
protect against the noise fluctuations on the ground line of the subsea electronics. This board isolates the
sensitive subsea electronics from potentially noisy grounds provided by the trigger and serial port inputs.
Noise can often be identified as repeating patterns at the edge of the usable range of data within
Discover’s waterfall display.
