5. Kurulum

5.1 Güç Bağlantısı

  1. Connect the supplied power lead to the power input on the rear panel of the oscilloscope.
  2. Plug the other end of the power lead into a grounded AC power outlet.
  3. Osiloskopu açmak için ön paneldeki güç düğmesine basın.

5.2 Prob Bağlantısı

  1. Connect the BNC connector of the passive probe to either Channel 1 (CH1) or Channel 2 (CH2) input on the front panel.
  2. Attach the ground clip of the probe to the circuit's ground point.
  3. Connect the probe tip to the test point in your circuit.
  4. Ensure the probe's attenuation setting (e.g., 1X or 10X) matches the setting on the oscilloscope for accurate readings.

6. Kullanım Talimatları

6.1 Temel İşlemler

  • Auto Scale: Press the 'AUTO SET' button to automatically adjust vertical, horizontal, and trigger settings for a stable waveform display. This function detects sine and square waves automatically.
  • Vertical Controls (VOLTS/DIV, POSITION): Use the VOLTS/DIV knobs to adjust the vertical scale (voltage per division) for each channel. The POSITION knobs shift the waveform vertically.
  • Horizontal Controls (SEC/DIV, POSITION): Use the SEC/DIV knob to adjust the horizontal scale (time per division). The horizontal POSITION knob shifts the waveform horizontally.
  • Tetikleme Seviyesi: Adjust the 'TRIGGER LEVEL' knob to set the voltage level at which the oscilloscope captures a waveform.

6.2 Gelişmiş İşlev

  • Dalga Formu Üreteci: Access the waveform generator menu to select and configure output waveforms such as Sine, Square, Ramp, Exponential, Noise, and DC. Connect the 'WAVE GEN' output to your circuit.
  • Tetikleme Modları: Utilize the 14 available trigger modes (Edge, Pulse, Video, Slope, Overtime, Window, Pattern, Interval, Under Amp, UART, LIN, CAN, SPI, IIC) to capture specific events. Select modes via the 'TRIGGER' menu.
  • Seri Protokol Kod Çözme: The oscilloscope supports decoding for RS232/UART, I2C, SPI, CAN, and LIN protocols. Configure these settings in the 'DECODE' menu to view decoded data.
  • Ölçümler: The device offers 32 types of automatic measurements with real-time statistics (maximum, minimum, standard deviation, etc.). Access these via the 'MEASURE' menu.
  • USB Bağlantısı: Connect a USB thumb drive to the USB Host port to save oscilloscope setups, waveforms, reference waveforms, CSV files, and images. The USB Device port allows for remote control from a computer using SCPI commands.
