Abstract

NIST provides an on-site calibration service of the accuracy of phase modulation (PM) noise, amplitude modulation (AM) noise and noise floor of the measurement systems at a customer's site using one or more portable PM/AM secondary noise standards. In this document, we describe the calibration procedure for an additive type of noise standard and derive the total (or combined) uncertainty associated with its PM and AM reference noise levels.
