2. Водич за поставување
Follow these steps to set up your Hantek DSO4084B oscilloscope:
- Отпакување: Carefully remove the oscilloscope and all accessories from the packaging. Verify all components are present against the packing list.
- Поврзување за напојување: Connect the power adapter to the oscilloscope's power input and then to a suitable power outlet.
- Поврзување со сонда: Connect the oscilloscope probes to the BNC input channels (CH1, CH2, CH3, CH4) as needed for your measurements. Ensure a secure connection.
- Вклучување: Press the power button located on the front panel to turn on the oscilloscope. The device will perform a self-test and display the Hantek logo.
- Првичен приказ: Upon startup, Channel 1 (CH1) will typically be active, displaying a horizontal line.

3. Упатства за работа
The Hantek DSO4084B offers intuitive controls for various measurement tasks.
3.1. Basic Waveform Adjustment
- Прилагодување Voltage: Use the vertical scale knobs (labeled "Vertical") for each channel to adjust the voltage per division (V/div). The button next to the knob allows for fine-tuning the voltage.
- Adjusting Waveform Position: Use the position knobs for each channel to move the waveform vertically on the screen.
- Enabling Multiple Channels: All four channels can be activated simultaneously. Use the dedicated buttons for each channel (CH1, CH2, CH3, CH4) to toggle them on or off. Adjust voltage and position for each active channel independently.
- Автоматско поставување: Притиснете го АВТОМАТСКИ button to automatically adjust the oscilloscope settings for a stable waveform display. For example, when measuring a DC 5V signal, the auto function might set the display to 2V per division.
3.2. Мерни функции
The oscilloscope provides extensive measurement capabilities:
- Автоматски мерења: Access over 32 types of automatic measurements by pressing the МЕАС button. This displays parameters like Vpp (peak-to-peak voltage), Vmax, Vmin, frequency, period, and more. Pressing МЕАС again will hide the measurement results.
- Систем за активирање: Utilize the advanced digital trigger system with over 14 types of trigger functions (edge, overtime, pulse, pattern, interval, etc.) to capture specific events.
- Декодирање на сериска магистрала: For serial bus protocols, the device can quickly and intuitively display bus protocol information in table form.
3.3. Coupling Settings (DC/AC)
To accurately measure different signal types, adjust the coupling setting:
- DC Coupling: Select DC coupling (usually via a menu accessed by a function button like F1) to measure both AC and DC components of a signal.
- AC спојка: Select AC coupling to block the DC component and only display the AC component of a signal. This is useful for observing small AC signals superimposed on a large DC offset.
- Ограничување на пропусниот опсег: The oscilloscope features a 20MHz bandwidth limit option (e.g., BW 20M). Activating this can help remove high-frequency noise or unwanted signals above 20MHz, providing a cleaner waveform for analysis.
- Adjusting Time Base: Use the horizontal scale knob (labeled "Horizontal") to adjust the time per division (s/div) to view more or less of the waveform horizontally.

4. Одржување
Proper maintenance ensures the longevity and accuracy of your Hantek DSO4084B oscilloscope:
- Чистење: Regularly clean the exterior of the oscilloscope with a soft, dry cloth. For stubborn dirt, use a slightly damp cloth with mild detergent. Avoid abrasive cleaners or solvents.
- Нега на екранот: Use a soft, lint-free cloth specifically designed for electronics screens to clean the display. Do not press hard or use harsh chemicals.
- Вентилација: Осигурајте се дека отворите за вентилација се чисти од прашина и пречки за да спречите прегревање.
- Складирање: When not in use, store the oscilloscope in a clean, dry environment away from direct sunlight, extreme temperatures, and excessive humidity.
- Грижа за сонда: Handle probes carefully. Avoid bending or stressing the cables. Store them properly to prevent damage to the tips and connectors.
- Калибрација: For critical measurements, periodic calibration by a qualified service center is recommended to maintain accuracy.
