This is a Determination & Findings document for a single-source federal contract award by the Air Force Technical Applications Center (AFTC/PZZF).

The procurement is for the Quasonix QSight™ L/S/C-Band Boresight System (Model QSX-QSGT-060-CA-PO, Quantity 1), a multi-band, high-powered Radio Frequency test source with integrated L/S/C-band transmitter and antenna. The system features remotely programmable modulation, data rates (24 kbps to 46 Mbps), and antenna polarization (LHCP, RHCP, and linear at any angle). Operating frequencies span 1435.5–1534.5 MHz, 1755.5–1849.5 MHz, 2200.5–2394.5 MHz, 4400.5–4939.5 MHz, and 5091.5–5149.5 MHz, with radiated EIRP levels of -40 to +40 dBm. The antenna features electronic amplitude and phase control with a 13.25-inch array diameter and 40° beamwidth. Required components include 60 feet of unified cable for power and data transmission, an Ethernet-based camera, and an MPT-50 positioner. The system must integrate with the agency-owned Quasonix Receiver Analyzer and be capable of operating in temperatures from -30°C to +55°C at up to 100% relative humidity with IP67 and NEMA-4X weather sealing. The product must be manufactured in the United States and be TAA-compliant.

The determination justifies single-source procurement under RFO 11.204(a)(2)(ii) (Brand Name authority), concluding that Quasonix is the only source reasonably capable of providing the required integrated L/S/C-band system with the exact form, fit, and function compatible with existing agency-owned test equipment and proprietary software handshakes. Previous purchases occurred under contracts FA930224P0048 and FA930223P0094 (both Commercial FFP, Brand Name set-asides, Cage Code 3CAJ9). The determination was signed by Contracting Officer Susana Dryer on 8 August 2026.
