Progress Towards an Accuracy Evaluation of NIST-F4 Cesium Fountain Clock

This work presents preliminary results towards the evaluation of the NIST-F4 cesium primary frequency standard. We present measurements of NIST-F4 frequency instability and evaluation of some of its systematic frequency shifts and shift uncertainties.
