Abstract : A 24' X 50' general purpose research platform has been located at San Vicente Lake. The facility is moored in 100 ft-minimum depth of water with approximately 4500 ft of unobstructed range. The barge is supplied with 440-3 phase ac power as well as 110-220 unregulated and 110 regulated 1 phase ac power. Boat and loading facilities are available. Equipment handling gear and tool set are included on the barge. Test capabilities at the facility include: source and receiver response, directivity pattern plots, null-balance measurements, Z and theta measurements. A set of calibrated PZT4 cylindrical crystals are available to accomplish the above tests. System frequency response is from 1kHz to 100 kHz. A set of checkout procedures and rules governing facility use are included in this report. A complete facility electronic equipment description and a set of suggested operational test procedures are also included. (Author)
