Description: This is a Request for Information (RFI) only. This is not a Request for Proposal, a Request for Quotation, and Invitation for Bids of an indication that NAWCAD LKE will contract for the items contained in the RFI. There is currently no solicitation package available. NAWCAD LKE is requesting information with regard to a commercial or modified commercial digital oscilloscope solution that is capable of calibrating various test instruments such as signal generators and test sets. The digital oscilloscope would be used on shipboard and at shore-based facilities and must conform to CLASS 4 requirements as listed in MIL-PRF-28800. The digital oscilloscope would also be subjected to operational conditions aboard both military and commercial land, sea, and air vehicles during periods of operation, transportation, and storage. The Navy will require the ability to perform any applicable firmware updates (that may become available from the vendor). A government approved technical manual that incorporates illustrated drawings and assembly diagrams, recommended parts replacement, maintenance and appropriate safety warnings will be required. Manufacturer test requirements will be invoked for any proposed modified commercial instrument to ensure all government specifications are met. The government's specific interests are as follows: - Interested companies who may have a single solution (do-all) box commercially available. - Interested companies who have an existing single box capable of being modified to meet the (do-all) general purpose specification as listed below. If responding to this configuration, please provide general product information on what the baseline model would be. NOTE: The government is not interested in a full developmental solution at this time. All corporate and proprietary information should be so marked and will be fully protected to the extent allowed. This RFI is for planning purposes only and shall not be construed as a request for proposal or as an obligation on the part of the Government to acquire any follow-on acquisitions. White papers should be submitted within 30 days of the publication date of this RFI. The Government does not intend to award a contract on the basis of this RFI or otherwise pay for the information solicited. No entitlement to payment of direct or indirect costs or charges by the Government will arise as a result of submission of responses to this RFI and Government use of such information. This RFI does not constitute the solicitation of proposals. Responders to this RFI may be requested to provide additional details/information based on their initial submittals. Questions and submissions may be submitted by email to Michael.t.miller7@navy.mil. The preferred candidate will be a single box, general purpose solution with specific performance requirements listed in paragraph 3.11 below. This general purpose solution incorporates the Navy requirements for both aircraft and shipboard applications. Additional requirements listed in paragraphs 1.0 - 3.10 and 3.12 - 3.16 also apply. The anticipated system will be a single box solution which will be used on the bench top (50 lbs. maximum) with maximum dimensions of 20" wide x 12" high x 10"deep. Power shall be 120Vrms @ a maximum of 500 watts. Comments regarding a single box solution (commercial or modified commercial) that may deviate slightly from the weight and size requirement should be included. Details of existing products that may be able to be modified to meet the specification should be provided. 1.0 SCOPE 1.1 General.
