1.0 BACKGROUND

This Statement of Work (SOW) is for the purchase of a Radio Frequency (RF) Power Calibrator for use in the Terminal Doppler Weather Radar (TDWR) Transmitter Microwave Assembly. It functions as a sensor to measure average RF power required for Nominal operation. This purchase is to replace the existing RF Power Calibrators and boost rotable stock which are obsolete and no longer available. The TDWR provides real-time weather product information and is a safety and efficiency related operational part of the National Airspace System (NAS).

This SOW describes acquisition services for the following:

RF Power Calibrator (Raytheon drawing G432183-1, Narda Part Number 70031)

All components, equipment, and spares with a consignee other than FAALC shall be marked in accordance with the marking requirements of ASTM-D-3951. In addition, each unit, intermediate, and exterior shipping container shall be marked with the following information:

National Stock Number Serial Number Part Number

Items received noncompliant with preservation and packaging (especially ESD items) are subject to be returned at no cost to the Government. In the event of an urgent need, the FAA may exercise the following action: The noncompliant packaged items will be retained and repackaged to specification at the FAA location. The FAA shall deduct packaging charges from the Delivery Order (DO).

Noncompliant ESD packages WILL be returned.

The FAA will endeavor to ship all items in reusable containers. All items shall be returned to the FAA in the same or equal containers (see a. above). In those instances where material is shipped in specialized containers (e.g., plastic, fiberglass shipping cases, metal crates, etc.) that material will be returned in the original container.
