Abstract :
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.<>
