Description
The National Institute of Standards and Technology (NIST) intends to negotiate a firm-fixed priced purchase order on a sole source basis with APS Dynamics, Inc. d.b.a. SPEKTRA for an upgrade to the existing Primary Vibration Calibration System. The upgraded system will enable uniaxial excitation of sensors across an extended frequency range while minimizing measurement uncertainty and cross-axis motion. The key components of the system include the Spektra CS18 vibration calibration system, Polytec OFV-5000/OFV-534 laser vibrometer, Spektra APS129, APS500, and APS600 shakers, and Spektra FECB electrical calibration unit. The delivery shall be made within twenty (20) weeks from the effective date of award and shall include a two (2) year warranty.
Some of the key requirements for the upgrade include:
• Full compatibility with the existing PVCS components currently in NIST’s possession
• Demonstrated capability to provide future upgrades using compatible components within the existing system architecture
• Seamless interoperability with existing shakers, control electronics, and calibration infrastructure
• No other vendor can provide an upgrade that maintains compatibility with the installed system without requiring substantial replacement of existing equipment.
