5. ປະຕິບັດການ Oscilloscope

The Rigol DHO1074 offers a user-friendly interface for capturing and analyzing waveforms. Key features include 4 analog channels, 70 MHz bandwidth, and a 12-bit vertical resolution for enhanced signal fidelity.

5.1 Basic Waveform Acquisition

1. ເປີດ: Ensure the oscilloscope is powered on as described in Section 4.3.
2. Connect Signal: Connect your signal source to an input channel using a compensated probe.
3. ຕັ້ງຄ່າອັດຕະໂນມັດ: ກົດ ອັດຕະໂນມັດ button on the front panel. The oscilloscope will automatically adjust vertical, horizontal, and trigger settings to display a stable waveform.
4. ການປັບດ້ວຍມື:
   • ໃຊ້ ສັດຕະວະແພດ knobs (VOLTS/DIV) to adjust the vertical scale (voltage per division) for each channel.
   • ໃຊ້ ລວງນອນ knob (SEC/DIV) to adjust the horizontal scale (time per division).
   • ໃຊ້ TRIGGER controls to set the trigger level and mode for stable waveform capture.

5.2 ຄຸນສົມບັດຂັ້ນສູງ

• ຄວາມລະອຽດສູງ: Benefit from the 12-bit vertical resolution, providing 16 times more quantization levels than standard 8-bit oscilloscopes, which improves measurement accuracy and reduces quantization noise.
• Deep Memory: The DHO1074 features a 50 Mpts maximum memory depth (expandable to 100 Mpts with option DHO1000-RLU-01), allowing for longer waveform captures at high sampອັດຕາດອກເບ້ຍ.
• Serial Decoding: Standard serial decoding capabilities include SPI, I2C, RS232/UART, CAN, and LIN, simplifying the analysis of common serial bus communications.
• ຟັງຊັນການວັດແທກ: Access various automatic measurement functions (e.g., Vpp, Vrms, Frequency, Period) via the ມາດຕະການ ເມນູ.
• ຟັງຊັນຄະນິດສາດ: Utilize built-in math functions (e.g., Add, Subtract, Multiply, Divide, FFT) to perform waveform analysis.
