4. Поставување

Follow these steps to set up your DSO-2104 oscilloscope for initial use:

1. Отпакување: Carefully remove the oscilloscope and all accessories from the packaging. Verify that all components are present and undamaged.
2. Поврзување за напојување: Connect the provided power cable to the power input on the rear panel of the oscilloscope and then to a suitable AC power outlet (100-240V, 50/60Hz). Ensure the power outlet is properly grounded.
3. Поврзување со сонда: Connect the oscilloscope probes to the desired BNC input channels (CH1, CH2, CH3, CH4) on the front panel. Ensure a secure connection.
4. Компензација на сондата: Before taking measurements, it is recommended to compensate your probes. Connect the probe to the probe compensation output (usually a square wave signal) and adjust the probe's compensation trimmer until a flat-top square wave is displayed on the screen.
5. Вклучување: Press the power button, typically located on the front panel, to turn on the oscilloscope. The display will illuminate, and the system will boot up.

5. Упатства за работа

The DSO-2104 offers a range of functions for waveform analysis. Here are basic operating guidelines:

5.1 Основни мерења

• Пропусен опсег: The device operates at a 100 MHz bandwidth across 4 channels.
• Sampling Оценка: Максималната сampling rate is 1 GSa/s, allowing for detailed capture of fast signals.
• Вертикална резолуција: With an 8-bit vertical resolution, the oscilloscope provides good precision for voltagмерења.
• Прикажи: Waveforms are displayed on the 7-inch (17.78 cm) LCD screen (800 x 480 pixels).

5.2 Adjusting Waveforms

• Вертикална скала (волти/дивидуал): Use the vertical control knobs for each channel (CH1-CH4) to adjust the voltage scale, changing the vertical amplitude of the displayed waveform.
• Вертикална положба: Use the position knobs to move the waveform vertically on the screen.
• Хоризонтална скала (Време/Дел): Use the horizontal control knob to adjust the time base, changing the horizontal compression or expansion of the waveform.
• Хоризонтална положба: Use the horizontal position knob to shift the waveform left or right.

5.3 Активирање

Активирањето ги стабилизира повторувачките бранови форми и ги доловува настаните од еден кадар.

• Ниво на активирање: Прилагодете го копчето за ниво на активирање за да ја поставите јачината на звукотtage point at which the oscilloscope will trigger.
• Режим на активирање: Select different trigger modes (e.g., Edge, Pulse, Video) using the dedicated trigger buttons or menu.
• Frequency Counting: The oscilloscope includes a frequency counting function for precise frequency measurements.

5.4 Складирање и повикување на податоци

• USB интерфејс: The integrated USB port allows for convenient data storage. You can save waveform data, screenshots, and settings to a USB flash drive.

7 Смена на проблеми

This section addresses common issues you might encounter with your DSO-2104 oscilloscope. If the problem persists, contact customer support.

7.1 Нема струја

• Проверете го кабелот за напојување: Осигурајте се дека кабелот за напојување е безбедно поврзан и со осцилоскопот и со штекерот.
• Проверете го штекерот: Проверете дали штекерот е функционален со вклучување на друг уред.
• Проверете го осигурувачот: If applicable, check the power fuse (refer to the device label for fuse specifications and replacement instructions, if user-replaceable).

7.2 No Waveform Displayed

• Проверете ја врската со сондата: Ensure probes are correctly connected to the input channels and the circuit under test.
• Check Channel Enable: Verify that the desired input channel is enabled on the oscilloscope.
• Adjust Vertical Scale: The waveform might be off-screen. Adjust the Volts/Div knob to a suitable range.
• Adjust Horizontal Scale: The waveform might be too compressed or expanded. Adjust the Time/Div knob.
• Check Trigger Settings: Incorrect trigger settings can prevent a stable waveform display. Try "Auto" trigger mode or adjust the trigger level.
• Копче за стартување/стоп: Ensure the oscilloscope is in "Run" mode (not paused).

7.3 Unstable Waveform

• Adjust Trigger Level: Fine-tune the trigger level to a stable point on the waveform.
• Select Correct Trigger Type: Choose the appropriate trigger type (e.g., Edge, Pulse) for your signal.
• Check Probe Compensation: Improperly compensated probes can lead to distorted waveforms. Perform probe compensation if necessary.
