5.1. Multi-Device Connection Example

This diagram illustrates a network setup where multiple Hantek oscilloscopes can be connected to a single computer. The oscilloscopes are connected to a PoE switch, which provides both data and power. The PoE switch then connects to the computer, allowing for centralized control and data acquisition from multiple devices. Fiber-optic communication is also shown as an option for extended distances.

6. Mode d'emploi

Once the software is installed and the device is connected, launch the Hantek application on your computer. The software interface is designed to be similar to a traditional benchtop oscilloscope, providing intuitive control over the device's functions.

6.1. Fonctions de l'oscilloscope

• Sélection des chaînes : Enable or disable the 4 analog channels (CH1-CH4) as needed.
• Commandes verticales : Ajuster le volumetage per division (V/DIV) and coupling (AC/DC/GND) for each channel. The device offers 1mV-10V/DIV sensitivity.
• Commandes horizontales : Adjust time base (s/DIV) to control the sweep speed.
• Déclenchement : Configure trigger source (CH1-CH4, EXT), mode (Edge, Pulse, Video, Slope, Timeout), and level to stabilize waveforms.
