    Current Profiler. This Operation Manual is intended to help HASCP users to get familiar with their system. This manual is specific for using the HASCP. The manual does not discuss all the technical issues of the HASCP. All documentation is being provided to you on USB storage device in a fully searchable, printable, electronic format.

  • Page 5: System Overview

    RTI is pleased to introduce the HASCP – Horizontal Acoustic Sediment and Current Profiler. The HASCP operates at a 3 different frequency configuration (600 kHz, 1200 kHz and 2.4 MHz) for sediment and velocity profiling using Narrow band and Broad band operation developed for the needs of scientists and engineers.

    5 Preparing for a Deployment RTI recommends the following checklist that may help the user towards a successful deployment. Structural Integrity – The structural integrity of cables and connectors are also important, be sure to there are no cuts or cracks in the cable or connectors. It is important to make sure that when reassembling the system that the nuts and bolts are tightened sufficiently.

    Figure 21. Plot of the horizontal profile showing the amplitude measurements by the various beams plotted across the range in m. This data was measured by the HASCP at the lake. The left hand axis is the velocity range (-5 to + 5 m/s) and the right hand axis represents the RSSI measured by the ADCP from 0 to 100 dB.
