NOTICE OF INTENT TO SOLE SOURCE REQUIREMENT DESCRIPTION: The Naval Air Warfare Center Weapons Division (NAWCWD) intends to procure a commercial Radio Frequency (RF) record and playback solution. The acquisition consists of: One (1) Rohde & Schwarz (R&S) IQW Wideband I/Q Recorder One (1) R&S SMW200A Vector Signal Generator Associated software, licenses (including the FSW-B517 digital streaming interface upgrade), cables, and support. The required solution must be capable of playing back previously recorded RF signals from a Government-owned library stored in a proprietary R&S In-phase Quadrature (I/Q) format. The system must stream the high-speed I/Q data and convert it back to the analog RF data needed to stimulate the EA-18G aircraft's electronic warfare systems in a laboratory test environment. SOLE-SOURCE RATIONALE: The Government has determined that Rohde & Schwarz is the only source capable of satisfying this requirement. This determination is based on the following: 1. Proprietary Data Compatibility: The EA-18G program's critical test data library, which consists of terabytes of classified threat recordings, exists exclusively in a proprietary Rohde & Schwarz I/Q data format. The Government’s existing I/Q data library is maintained in proprietary R&S format. The required solution must use those files natively or otherwise demonstrate preservation of data integrity, metadata, timing, sample rate, bandwidth, phase coherence, and signal fidelity without introducing unacceptable schedule risk. Market research did not identify an available non-R&S solution that met those conditions. 2. Unacceptable Schedule Risk and Cost: As determined by market research (Sources Sought N6893627Q5001), The alternate OEM solutions evaluated by the technical activity relied on file translation, conversion, or non-native interface approaches that would require validation of converted I/Q data and present unacceptable data-fidelity and schedule risk.
