Morphology
The meaning of 'electronic scanner' is directly and compositionally derived from 'electronic' (relating to electronic technology) + 'scanner' (a device that detects or digitizes information). This noun–noun compound follows a common, cross-linguistic compounding pattern and would be readily understood by a B1 learner who knows both constituent words.
Etymology
Electronic scanner comes from the idea of 'to scan' — a quick sweep like an eye or a torch moving across a scene, and the tool that does this is a scanner. Early radio machines 'scanned' many frequencies in the same way, so an electronic scanner is a device that looks across radio channels to find signals.
