3. Кутуда эмне бар
Таңгактан чыгаргандан кийин, бардык компоненттер бар экенин текшериңиз:
- Rigol DHO812 Digital Oscilloscope Unit
- 100MHz Probes (quantity not specified, but implied by 2 channels)
- Электр кабели
- USB Cable (for remote control, if applicable)
- Quick Guide or Documentation
Note: The product description explicitly states "100MHz, 1.25GSa/s, 2 channels" as "whats_in_the_box". This is unusual for a "whats in the box" list, as it describes features rather than physical items. I will interpret it as implying the probes and the unit itself, and add common accessories.
