STATEMENT OF WORK

Title: Primary Vibration Calibration System Upgrade

I. BACKGROUND

The Quantum Measurement Division (QMD) at the National Institute of Standards and Technology (NIST) provides the fundamental basis for the measurement of mass, force, and vibration in the United States by maintaining and modernizing primary standards linked to the International System of Units (SI). The Division performs leading-edge research to develop advanced measurement technologies and provides calibration services that support U.S.

industrial productivity and ensure equity in trade.

QMD requires an upgrade to its existing Primary Vibration Calibration System to sustain and enhance these capabilities. This acquisition directly supports the Division’s mission by modernizing the technical infrastructure necessary to deliver high-accuracy vibration calibration services. The upgraded system will enable uniaxial excitation of sensors across an extended frequency range while minimizing measurement uncertainty and cross-axis motion.

Purpose/Objective: The purpose of this requirement is to procure and integrate the electronics, software, laser vibrometer, and high-frequency, high-performance shaker necessary to perform primary vibration calibration.

The upgraded system shall include all hardware and software required to routinely deliver low-uncertainty vibration calibrations. It shall meet or exceed the performance of the current NIST Primary Vibration Calibration System (PVCS) across its full operating range and provide the specific performance enhancements identified in the technical specifications below.

The system shall maintain compatibility with existing electrodynamic shakers and shall be supported, including maintenance and parts availability, for a minimum of ten (10) years.

II. SCOPE

The Contractor shall upgrade the existing Primary Vibration Calibration System, which consists of Spektra CS18 vibration calibration system, Polytec OFV-5000/OFV-534 laser vibrometer, Spektra APS129, APS500, and APS600 shakers (with associated power amplifiers and zero-position controllers), and Spektra FECB electrical calibration unit.
