RIGOL DHO802 דיגיטאַל אָסצילאָסקאָפּ באַניצער מאַנואַל

1. הקדמה

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.

3.3 זאָנד קאַנעקשאַן

The DHO802 comes with two passive probes. To connect a probe:

1. Align the BNC connector of the probe with one of the input channels (CH1 or CH2) on the front panel.
2. Push the connector in and twist clockwise until it locks into place.
3. Attach the probe's ground clip to a common ground point in your circuit.
4. For accurate measurements, ensure the probe compensation is correctly adjusted. Refer to the "Probe Compensation" section in the full manual for detailed instructions.
