Topside Provided Isolation
The two most common sources of electrical noise (interference) 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.
