E-MAIL: Artistine R. Lethcoe-Reid, A.LETHCOE-REID@larc.nasa.gov. THIS NOTICE CONSTITUTES AMENDMENT NO. One (1) TO THE COMBINED SYNOPSIS/RFQ FOR Flat Panel Display. Companies shall acknowledge all amendment(s) in their quote. This notice serves as the official amendment to subject synopsis/RFQ and a written amendment will not be issued. The purpose of this amendment is to provide answers to the following questions: Question 1 -- As there are many uncertainties as to the meaning of "ruggedized", what is the usage of the monitors. Answer -- The definition of "ruggedized" is as follows: Meets requirements of MIL-STD 461E (Electronic Emissions and Susceptibility Requirements for the control of Electromagnetic Interfaces). Vibration (+/- 2G random); Shock (20 G non-operating, Crash safety impact of 40 G). The flat panel will be used onboard a B-757 Aircraft as a part of the research video system. Question 2 -- Your description mentions a "ruggedized" flat panel display. This term is widely open to interpretation. Do you have a set of environmental specifications to which the display must have been tested or designed. By this I mean shock, vibration, temperature, EMI/RFI, etc. These specifications may be defined by a standard industrial or military classification. Could you please provide me with more details and this will significantly affect the price of the units? Answer -- Meets requirements of MIL-STD 461E which is answered in question # 1. Question 3 -- Is there a certain brand you prefer or is the display being modified by vendor by fitting a rack to it and if, the display is a modified display panel, such as a Viewsonic or Compaq brand, are there any schematics available? Answer -- There are several sources for ruggedized, 19" rack mountable displays on the market. There are no schematics available. The definition of "ruggedized" is answered in question #1. Question 4 -- The solicitation requires three (3) each "ruggedized flat panel displays". However, no environmental requirements are listed. Can you please provide me with the requirements that categorizes this item as Ruggedized? Answer -- See question #1. Question 5 -- Is there already a qualified source? Answer -- No Question 6 -- Can you tell me what workstation and video card will be used to drive the display. Is the workstation also a rugged unit? Will full motion video be run on the display? Answer -- These units will be used onboard a B-757 aircraft as part of a research video system. The driver for the units will be a PESA routing switch system, controlled by a rugged laptop personal computer (Fieldworks). Question 7 -- Are there any rugged environmental specifications (shock, vibration, temperature, etc.) for this procurement? Are there any additional anticipated awards for this product? Answer -- See answer to question 1. These units will be used onboard a B-757 aircraft as a part of the research video system. We have no idea about future requirements for this product. Question 8 -- "The horizontal frequency range for the monitor is listed as 24-80 kHz; however, both S-video and NTSC inputs are mentioned which typically have a 15.75 kHz horizontal frequency. Are the S-video and NTSC inputs really required? Answer -- Yes, the S-Video and NTSC inputs are required for usage in the onboard research Video System, even with the lower frequency range. We do not need a strictly RGB (w/sync on Green) rugged flat panel since the majority of our video signals are S-Video. Additional specifications are as follows: (1) EMI/EMC requirements -- All applicable EMC requirements for Airborne Naval Equipment as specified in MIL-STD-461E (Electronic Emissions and Susceptibility Requirements for the Control of Electromagnetic Interfaces). (2) Shock & Vibration Requirements -- All applicable Shock & Vibration requirements for the EP-3E Aircraft profile which includes Operational Shock, Non-Operational Shock, Random Vibration, and Crash Safety as detailed below: Operational Shock: Equipment shall not suffer damage or fail to provide the performance specified when subjected to 18 impact shocks of 10g's, consisting of 3 shocks in opposite directions along each of three mutually perpendicular axes, each shock pulse having a time duration of 11 msec. Non-operational Shock: With excursion stops or bumpers in place and with maximum rated load applied in a normal manner, the chassis and any attaching devices shall withstand at least 12 impact shocks of 40g's, consisting of 2 shocks in opposite directions along each of three mutually perpendicular axes. Each shock impulse shall have a time duration of 11 msec. Bending and distortion shall be permitted, however, there shall be no failure to the attaching joints, and the equipment or dummy load shall remain in place. Random Vibration: When normally mounted, the equipment shall not suffer damage or fail to meet specified performance when subjected to a vibration qualification spectrum ranging from a Frequency of 10 Hz @ Acceleration Spectral Density of .005 g2/Hz through a Frequency of 2000 Hz @ Acceleration Spectral Densitsy of .0004 g2/Hz. The vibration shall be applied for two (2) hours in each of three perpendicular axes. Crash Safety: Withstands Crash Safety impact of 40 G. The due date for receipt of offers is not extended. Companies shall provide the information stated in the synopsis/RFQ posted on the NASA Acquisition Internet Service (NAIS) on 03/30/00. Documents related to this procurement are available over the Internet and are in Microsoft Office Suite (Word 6.0, Excel 5.0, or PowerPoint 4.0) format and reside on the World Wide Web (WWW) server which may be accessed using a WWW browser application.
