5. Configuració
5.1 Engegar el dispositiu
- Connect the USB Type-C power adapter to the oscilloscope's power input port.
- Connecteu l'adaptador d'alimentació a una presa de corrent adequada.
- Press the power button located on the front panel to turn on the oscilloscope. The display will illuminate.
5.2 Connexió i compensació de la sonda
- Connect a test probe to one of the BNC input channels (CH1-CH4) on the front panel.
- Attach the probe tip to the probe compensation output (usually a square wave signal output on the front or side).
- Adjust the probe compensation screw (located on the probe body) until the square wave displayed on the screen has flat tops and bottoms, without overshoot or undershoot.
- Repeat this process for all probes you intend to use.
6. Instruccions de funcionament
6.1 Basic Waveform Display
- Selecció de canals: Press the CH1, CH2, CH3, or CH4 buttons to enable or disable a channel.
- Vertical Scale: Utilitza el Escala Vertical knob to adjust the volts per division (V/div) for the selected channel.
- Posició vertical: Utilitza el Posició vertical knob to move the waveform up or down on the screen.
- Horizontal Scale: Utilitza el Escala horitzontal knob to adjust the time per division (s/div).
- Posició horitzontal: Utilitza el Posició horitzontal knob to shift the waveform left or right.
6.2 Trigger Functions
The oscilloscope offers various trigger types to stabilize and capture specific parts of a waveform.
- Premeu el botó Disparador button to access trigger settings.
- Select the desired trigger type (e.g., Edge, Pulse, Video) from the menu.
- Adjust the trigger level using the dedicated Nivell de disparador knob or via the touchscreen.
- Choose the trigger source (CH1-CH4) as needed.
6.3 Touchscreen and Gesture Control
The 7-inch touchscreen allows for intuitive control.
- Toca: Select menu items, buttons, or adjust settings.
