About this file
This is a Purchase Description for a hardware technology refresh of accessory components for Keysight N5242A Vector Network Analyzers. The document specifies requirements for the Air Force Metrology & Calibration Program (AFMETCAL) to procure replacement accessories for sixteen Precision Measurement Equipment Laboratories (PMELs). The contractor shall deliver six items totaling eight units: two Keysight N4696D 7mm E-Cal Kits, one Keysight N4691D 3.5mm E-Cal Kit, one Keysight 85053B 3.5mm Ver Kit, two Maury 2633C1 NMD 3.5mm(f) to 7mm adapters, one Maury 8022S1 3.5mm(f) to 7mm adapter, and one Maury 8022T1 3.5mm(m) to 7mm adapter. The procurement addresses the replacement of legacy accessory suites that have exceeded their economic service life and are demonstrating degraded reliability and reduced supportability.
The contractor must provide the commercially available operator's manual and default warranty and technical support offered by the vendor with each unit. Testing and inspection will occur at a destination specified elsewhere in the contract using test equipment with first echelon certification traceable to the National Institute of Standards and Technology (NIST) or other AFMETCAL approved sources. The contractor remains responsible for all inspections and quality control checks at the point of fabrication to ensure performance meets or exceeds all requirements specified in the Purchase Description. The document references an attachment for Data Requirements but does not specify response dates, award dates, or pricing terms.

PURCHASE DESCRIPTION
FOR
Accessories for Keysight N5242A
1.0 SCOPE: This Purchase Description (PD) defines the requirements for a hardware technology refresh of accessory components for the Keysight N5242A Vector Network Analyzer (VNA).
The contractor shall deliver replacement components and accessories to support operations across sixteen (16) designated Air Force Metrology & Calibration Program (AFMETCAL) Precision Measurement Equipment Laboratories (PMELs).
1.1. Background: AFMETCAL sustains critical physical and electrical measurement standards for the United States Air Force. The legacy accessory suites currently integrated with the Keysight N5242A VNAs at various PMEL locations have surpassed their economic service life and are demonstrating degraded reliability and supportability. Replacement of these aging components is required to restore full calibration capability and prevent mission downtime.
1.2. Objective: The primary objective of this effort is to procure and deliver modernized, fully compatible VNA accessory components. The technology refresh will eliminate equipment reliability bottlenecks, ensure operational continuity at numerous PMEL sites, and maintain the precise calibration baselines mandated by AFMETCAL
