  Precise spectroscopy of oscillating fields plays significant roles in many
fields. Here, we propose an experimentally feasible scheme to measure the
frequency of a fast-oscillating field using a single-qubit sensor. By invoking
a stable classical clock, the signal phase correlations between successive
measurements enable us to extract the target frequency with extremely high
precision. In addition, we integrate dynamical decoupling technique into the
framework to suppress the influence of slow environmental noise. Our framework
is feasible with a variety of atomic and single solid-state-spin systems within
the state-of-the-art experimental capabilities as a versatile tool for quantum
spectroscopy.
