1. పరిచయం

The RIGOL DHO802 Digital Oscilloscope is a high-performance instrument designed for precise signal analysis. It features ultra-low background noise for pure signal acquisition and a 12-bit hardware high resolution across all series. With up to 70MHz analog bandwidth and 2 analog channels, it supports real-time sampling rates up to 1.25 GSa/s and a storage depth of up to 25 Mpts. The Ultra Aqua mode provides an impressive 1 million wfms/s waveform capture rate, making it ideal for capturing transient events.

Key features include gray scale digital real-time brightness function, waveform search and navigation, a 7-inch 1024x600 high-definition touch screen, and a new Flex knob for enhanced interactive experience. Connectivity options include USB Device & Host, LAN, and HDMI ports. The compact design ensures convenient maneuverability, and it supports online version upgrades.
