E-MAIL: Chanthy Iek, chanthy.iek.grc.nasa.gov. The Government intends to acquire a commercial item using FAR Part 12 and the Simplified Acquisition Procedures set forth in FAR Part 13. This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation, which is issued as a Request for Quotation (RFQ); quotes are being requested and a written solicitation will not be issued. The information required by FAR Subpart 12.6 is included in the on-line RFQ linked above or it may be accessed at http://procurement.nasa.gov/cgi-bin/EPS/bizops.cgi?gr=C&pin=. NASA/Glenn Research Center (GRC) plans to acquire a laser scan Vibrometer System for an experimental test that is being setup for the study of liquid fluid surface waves in a container with an emphasis on wave turbulence and ripple effect near the wall boundary. This test is for ground-based support of a space experimentalproject entitled "Ripple Turbulence". It has been determined that a laser vibrometer system shall be used for measuring the dynamics of liquid surface ripple waves at both single point and multiple scan points over a specified area of interest ranging from a few millimeter-squares to a few centimeter-squares in size. The ripple wave motion is expected to have a frequency variation from 25 Hz to 2 kHz with wave velocity of up to +/- 8 m/s. The featured capabilities of the laser scan vibrometer should include the following: 1. Rapid scanning rate. 2. Fully integrated signal processing and video imaging with live display during both test setup and test run to be sure the scanned data will be taken over the area of interest and information is conveyed in real time for an observation of dynamic motion. 3. System calibration. Data validation against any entrained noise signals to assure the data obtained is free from any unwanted vibrating elements associated with the system structure dynamics and source of power supply. 4. Data reduction and processing with standard FFT mode function to perform full integration of acquired dynamic raw data, and plot results in selected domain of frequencies in terms of acceleration, velocity, displacement, and power spectrum in appropriate form of coordinate system. 5. System-support software for control, acquiring data, processing, and display needs. The system manufacturer needs to provide full support of all aspects of the software, including test validation and documentation of all conceivable features. 6. Backup support of the system for both hardware and software, including remote consultation (question and answer). If necessary dispatch of personnel to the work site where equipment is being utilized. Questions regarding this acquisition must be submitted in writing (e-mail is acceptable), no later than June 9, 2000. It is the quoter's responsibility to monitor this site for the release of amendments (if any). Potential quoters will be responsible for downloading their own copyof this notice, the on-line RFQ and amendments (if any). Posted 05/30/00 (D-SN459618). (0151)
