| Abstract: |
The US Army Primary Standards Laboratory (APSL) is committed to providing services to its customers which are accurate, traceable to the National Institute of Standards and Technology (NIST), delivered on-time, and continuously improving. Since 2000, the APSL has been accredited in most of the major measurement parameters to the ISO/IEC 17025 quality standard by the American Accreditation of Laboratory Association. The quality management system of the APSL is also registered by NSF-ISR to ANSI/ISO/ASQ Q9001:2000. This paper will report on an interlaboratory comparison (ILC) of measurements performed on Vector Network Analyzers (VNAs). The ILC was conducted with the three primary standards laboratories of the US Department of Defense (US Air Force Primary Standards Laboratory, US Navy Primary Standards Laboratory, and APSL), NIST, and two industry laboratories (Agilent Technologies Santa Rosa Metrology Services and Anritsu Company Standards Laboratory). This will provide an appraisal of the capabilities and degree of equivalence of the participant laboratories by measuring a set of 3.5 mm 2-port devices, at the following 27 frequencies: 1.0 to 26 GHz in 1 GHz increments and 26.5 GHz. The devices consist of a set of 4 Hewlett Packard 8493C attenuators with attenuations of 6, 10, 20 and 40 dB. This report will provide the results of the ILC which demonstrated proficiency of VNA operators in the context that they can produce measurement results consistent with other comparable laboratories. REMARK: The report of these ILC results requires a courtesy concurrence of all participants. |
