1 Introduction

1.1 Scope

This drawing describes the characteristics of the microwave waveguide switch SP3T used in the Weather Systems Processor (WSP) system for the collection and prediction of weather phenomena.

Section 2 provides the characteristics for the vendor supplied equipment and the correlation between Procuring Activity Control numbers and vendor part numbers. Table 2-1 summarizes the part numbers identified by this drawing, the approved vendors, and corresponding vendor part numbers. Table 2-2 summarizes the vendors’ cage codes and addresses. This CID may describe items produced by multiple vendors. Shipping requirements are provided in Section 3. Quality requirements are provided in section 4.

1.2 Purpose

This drawing provides the data required to fulfill the requirements for Commercial Item Description (CLIN 008, Data Item B09) and Commercial Off the Shelf (COTS) Hardware Description Document (CLIN 008, Data Item F22) deliverables. It further provides the correlation between the WSP unique drawing numbers and vendor part numbers.

1.3 Reference Documents

Instructions for installing adapter cards, loading software, setting switches and jumpers, and applying labels are included in the Next Higher Assembly (NHA) drawings where the commercial items are incorporated in the WSP system.

The following Data Item Descriptions have been used as a reference/guide in the preparation of this document:

DI-SDMP-81261 Commercial Item Description (CID) RCR-015 Commercial Off the Shelf (COTS) Hardware Description Document.

1.4 Alternate Parts and Consistency

Alternate parts for a particular Procuring Activity Control Number shall provide form, fit, and function compatibility for the WSP. Capabilities beyond those requirements specified in section 2 are acceptable as long as WSP performance is not impacted. Vendor part numbers marked “Superceded” are acceptable, but are not the preferred choice.
