The measurement of stellar radial velocities (RVs) requires spectrographs that break the light into its component wavelengths and detectors to record the resulting spectrum. In this chapter, we give a brief overview of the essential equipment needed for stellar RV measurements, namely spectrographs and detectors. Entire books are required to do the subject justice, and an excellent source is the text Spectroscopic Instrumentation: Fundamentals and Guidelines for Astronomers by Eversberg & Vollman (2015). Rather, in this chapter, we will cover just the basics principles of instrumentation needed for RV measurements.
