Morphology
The meaning is directly and predictably built from 'sampling' (periodic measurement) and 'frequency' (rate over time): together they denote the rate at which samples are taken. This noun–noun composition follows a common, cross-linguistic pattern so a B1 learner who knows both constituents can reasonably infer the MWE's meaning even if the unit (Hz) is technical.
Etymology
Sampling frequency is like taking many quick photos of a moving scene. sampling means taking small pieces of a sound or signal and frequency means how often you take them, usually 'times per second'. So, the more often you sample, the more the digital signal matches the original.
