5. عملیاتي لارښوونې

5.1. Basic Oscilloscope Operation

• Vertical Controls: Use the vertical knobs for each channel (1-4) to adjust the voltage scale (V/div) and vertical position of the waveform.
• Horizontal Controls: Use the horizontal knobs to adjust the time base (s/div) and horizontal position of the waveform.
• محرک سیسټم: The trigger system allows for stable waveform display. Access trigger settings via the 'Trigger' menu. You can select trigger type (Edge, Pulse, Video, etc.), source channel, slope, and level. The advanced trigger functions include options for UART, CAN, SPI, and I2C buses.
• Auto Scale: Press the 'Auto Scale' button for automatic adjustment of vertical and horizontal settings to display a stable waveform.

5.2. Mathematics Functions

The oscilloscope supports various mathematical operations on waveforms. Access the 'Math' menu to select operators (e.g., +, -, *, /) and source channels. This allows for complex signal analysis, such as adding or subtracting signals from different channels.

۴.۲. د اندازه کولو دندې

• اتوماتیک اندازه کول: The device offers over 32 types of automatic measurements. Access the 'Measure' menu to select parameters like frequency, period, amplitude, Vmax, Vmin, Vpp, etc.
• د کرسر اندازه کول: Use the 'Cursor' function to manually measure voltage and time differences on the waveform.

۸.۴. د څپو شکل جنراتور

The integrated waveform generator can produce various signal types:

• سینه څپې
• مربع څپې
• Ramp (Triangular/Trapezoidal)
• نبض
• شور
• DC
• Arbitrary waveforms (Arb1, Arb2, Arb3, Arb4)

Access the 'Wave Gen' menu to select the waveform type, frequency (up to 25MHz), amplitude (up to 1.5V), and offset. You can also load custom arbitrary waveforms from a USB flash drive.

5.5. Saving and Updating

• د USB ذخیره کول: The oscilloscope supports U-stick storage for saving waveforms, settings, and screenshots. Insert a USB flash drive into the front panel USB host port.
• د سیسټم تازه کول: Firmware updates can be performed via the USB device port. Refer to the official Hantek webد وروستي فرم ویئر او لارښوونو لپاره سایټ.
