Import Tips

Classify as signal generator only if primary function; avoid 8542 if merely semiconductor devices without generation capability

Provide datasheet showing waveform generation specs to distinguish from simple oscillators (HTS 8548)

For modules, declare intended end-use as test equipment to prevent reclassification as ADP parts
