Systematic errors in NIST-7

Systematic errors in NIST-7

We describe a continuing, in-depth evaluation of NIST's new optically pumped frequency standard, in which all known sources of systematic error are investigated; most by two or more independent techniques. Additionally, we have used both analog (fast sine-wave modulation) and digital (slow, squ...

Description
Summary:We describe a continuing, in-depth evaluation of NIST's new optically pumped frequency standard, in which all known sources of systematic error are investigated; most by two or more independent techniques. Additionally, we have used both analog (fast sine-wave modulation) and digital (slow, square-wave modulation) servo systems during the evaluation.< >
