5. Persediaan
5.1 Menghidupkan Peranti
- Connect the USB Type-C power adapter to the oscilloscope's power input port.
- Palamkan penyesuai kuasa ke salur keluar elektrik yang sesuai.
- Tekan butang kuasa yang terletak pada panel hadapan untuk menghidupkan osiloskop. Paparan akan menyala.
5.2 Sambungan dan Pampasan Probe
- 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. Arahan Operasi
6.1 Paparan Bentuk Gelombang Asas
- Pemilihan Saluran: Press the CH1, CH2, CH3, or CH4 buttons to enable or disable a channel.
- Skala Menegak: Gunakan Skala Menegak knob to adjust the volts per division (V/div) for the selected channel.
- Kedudukan Menegak: Gunakan Kedudukan menegak knob to move the waveform up or down on the screen.
- Skala Mendatar: Gunakan Skala Mendatar knob to adjust the time per division (s/div).
- Kedudukan Mendatar: Gunakan Kedudukan Mendatar 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.
- Tekan ke Pencetus butang untuk mengakses tetapan pencetus.
- Select the desired trigger type (e.g., Edge, Pulse, Video) from the menu.
- Adjust the trigger level using the dedicated Tahap Pencetus 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.
- Ketik: Select menu items, buttons, or adjust settings.
- Cubit-untuk-Zum: Use two fingers to zoom in or out on waveforms (horizontal and vertical scaling).
- Seret: Move waveforms or menu elements across the screen.
6.4 Penyimpanan dan Ketersambungan Data
