This document is a Single Source Justification (Simplified Acquisition) for the Air Force, specifically for acquiring a Keysight CAI Kit 85521A for the PNA (Portable Network Analyzers) at Hill AFB, Utah. The acquisition involves 22 Keysight Technologies 85521A, 4-in-1 OSLT calibration kits for F-22 systems, with each kit to be delivered with the manufacturer's user manual and a 1-year manufacturer's warranty.

The justification for single-source procurement is based on comparative testing, where the Keysight 85521A mechanical calibration kit is the only kit proven to provide necessary accuracy and reliability for FieldFox Network Analyzer calibration in critical aircraft maintenance applications. Technical testing revealed that alternative calibration kits produced consistently inaccurate voltage standing wave ratio (VSWR) readings. The contracting officer has determined that only a single source is reasonably available, with the document dated April 2021 and the determination signed on 18-Aug-2025. The document also indicates the government intends to conduct a market survey to identify potential alternative sources for future acquisitions.
