Analysis sector was among one of the departmental subdivisions utilized aboard Federation starships during the mid-23rd century.

When the USS Enterprise received a seemingly gibberish communication in 2267 from a source later determined to be Nomad, Lieutenant Uhura informed Captain Kirk that it was "impossible to get any clearer" from her station, Kirk had Uhura send the message to the analysis sector to have them study and decode it. In relaying her message, Uhura stated, "Analysis sector, channel 1, main computer, decode." (TOS: "The Changeling")
