3. عملیاتي لارښوونې
The Hantek DSO4084B offers intuitive controls for various measurement tasks.
3.1. Basic Waveform Adjustment
- د حجم تنظیم کولtage: 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.
- اتوماتیک تنظیم کول: فشار ورکړئ آټو 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.
۴.۲. د اندازه کولو دندې
The oscilloscope provides extensive measurement capabilities:
- اتوماتیک اندازه کول: Access over 32 types of automatic measurements by pressing the MEAS button. This displays parameters like Vpp (peak-to-peak voltage), Vmax, Vmin, frequency, period, and more. Pressing MEAS again will hide the measurement results.
- محرک سیسټم: Utilize the advanced digital trigger system with over 14 types of trigger functions (edge, overtime, pulse, pattern, interval, etc.) to capture specific events.
- Serial Bus Decoding: 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.
- د AC جوړه کول: 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.
- د بینډ ویت حد: 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. ساتنه
Proper maintenance ensures the longevity and accuracy of your Hantek DSO4084B oscilloscope:
- پاکول: 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.
- د سکرین ساتنه: Use a soft, lint-free cloth specifically designed for electronics screens to clean the display. Do not press hard or use harsh chemicals.
- وینټیلیشن: ډاډ ترلاسه کړئ چې د هوا د تویېدو د مخنیوي لپاره د هوا د تویېدو دروازې له دوړو او خنډونو څخه پاکې دي.
- ذخیره کول: When not in use, store the oscilloscope in a clean, dry environment away from direct sunlight, extreme temperatures, and excessive humidity.
- د تفتیش پاملرنه: د پروبونو سره په احتیاط سره لاس ورکړئ. د کیبلونو د کږولو یا فشار ورکولو څخه ډډه وکړئ. دوی په سمه توګه ذخیره کړئ ترڅو د څوکو او نښلونکو ته زیان ونه رسیږي.
- اندازه کول: For critical measurements, periodic calibration by a qualified service center is recommended to maintain accuracy.
