Apollo Spacecraft S Band Communication System, Part 12

The Apollo radio uplink signal was an intricate composite of Doppler carrier, voice, data, and ranging information, encoded in a variety of modulations, sometimes stacked upon one another. Modern test equipment makes what was on the very edge of the possible in the 1960s remarkably easy to reproduce today, if you can find where in the maze of nested menus lurk the commands you need to do the job.
