Oscilloscope

An oscilloscope is an electronic test instrument used to observe, measure, and record electrical signals as they vary over time, widely used in electronic R&D, production testing, maintenance, and scientific research. In foreign trade, oscilloscopes are precision electronic measuring instruments, typically classified under HS code 90302010 (cathode-ray oscilloscopes) or 90302090 (other oscilloscopes). Use cases include export quotations, contract signing, customs declaration and inspection, logistics and transportation, and after-sales service. Precautions: 1. Technical parameters (bandwidth, sampling rate, number of channels, etc.) must be clearly specified to avoid disputes caused by specification mismatches; 2. Some high-bandwidth oscilloscopes may be subject to export controls (such as U.S. EAR regulations), and it is necessary to confirm whether a license application is required; 3. Transportation requires shock and moisture protection, and insurance should be purchased; 4. After-sales service should provide calibration certificates or warranty terms. Difference from other terms: An oscilloscope is different from a multimeter (which only measures basic electrical parameters), a spectrum analyzer (frequency-domain analysis), and a logic analyzer (digital signals); its core function is time-domain waveform display. Foreign trade practitioners should be familiar with product certifications (CE, FCC, RoHS) and target market access requirements.
