5. මෙහෙයුම් උපදෙස්

This section outlines the basic steps for operating your VOLTCRAFT DSO-2020 USB oscilloscope.

5.1 Launching the Software

After successful installation and connection, launch the VOLTCRAFT oscilloscope application from your computer's desktop or start menu. The software interface will display a virtual oscilloscope screen, similar to a traditional benchtop unit.

5.2 Basic Signal Acquisition

1. Connect Signal: Attach the probe to the circuit point you wish to measure.
2. නාලිකා තේරීම: In the software, enable the desired channel (CH1 or CH2).
3. Vertical Scale (Volts/Div): Adjust the vertical scale to fit the signal amplitude on the screen.
4. Horizontal Scale (Time/Div): Adjust the horizontal scale to view the signal's period or frequency.
5. ප්‍රේරක සැකසුම්: Configure the trigger source, type (edge, pulse), and level to stabilize the waveform. The software provides controls similar to a physical oscilloscope.
6. ස්වයංක්‍රීය සැකසුම: Utilize the automatic setup function within the software. This feature automatically adjusts the vertical and horizontal settings to display the input signal optimally.

5.3 Data Processing and Export
