It is helpful to know the terminology describing the key features of the Spectrum Window, and the basics are displayed in Figure 3.13, “Key features of the Spectrum Window”. From the top down, you'll find the window's title, a row of buttons that perform certain actions (Section 2)H, below), a row of little displays showing information about cursor positions and separation (Section 2)G, below), then the spectrum itself, with axes displayed. In the following sections, we'll go over the salient details of each feature. This won't be an exhaustive treatment, but should just give you enough familiarity to save yourself some time and keep you from flailing about.
