We present a measurement of the absolute frequency of the 5s\(^2\) \(^1\)S\(_0\) to 5s5p \(^3\)P\(_0\) transition in \(^{87}\)Sr, which is a secondary representation of the SI second. We describe the optical lattice clock apparatus used for the measurement, and we focus in detail on how its systemat...
