Morphology
The meaning is directly derivable from combining 'spectrum' (a band of wavelengths or colors) with 'analysis' (systematic examination): it simply denotes the examination of a spectrum. This is a standard compositional noun-noun technical compound found cross-linguistically, so a B1 learner who knows both constituents can reasonably infer the MWE's meaning.
Etymology
Spectrum analysis comes from the idea of a spectrum, a band of colours like a rainbow, and analysis, which means careful study. Scientists split light and read the pattern of colours to learn 'what a substance is made of', so spectrum analysis means studying those colour patterns to find out what a sample contains.
