- Summary:
- A calibration service currently being offered by NBS for attenuation and phase shift at 30 MHz is described. The service offers measurements on coaxial attenuators that are either fixed (standard attenuation) or variable for incremental (step) attenuation. Waveguide-below-cutoff variable attenuators with coaxial connectors are also calibrated for incremental attenuation. Ranges of capabilities and estimated limits of systematic and random uncertainty are presented. Calibration of phase shifters which provide fixed (insertion) phase shift and those with variable phase shift (phase shift difference) is described. Definitions, capabilities of the system and techniques of calibration are given. The standards, measurement uncertainties, results from intercomparisons quality assurance and statistical control of the system are discussed and analyzed. Representative reports of calibration are also included.
