5. Nastavitev

1. Napajalni priključek: Connect the provided USB charger and cable to the device's power input port. Plug the charger into a suitable power outlet.
2. Vklop: Press the 'POWER' button located on the front panel to turn on the device.
3. Povezava sonde: For oscilloscope measurements, connect the 100MHz probes to the CH1 and CH2 BNC input connectors. Ensure the probes are securely twisted into place.
4. Kompenzacija sonde: Before taking measurements, it is recommended to compensate the probes. Connect the probe tip to the probe compensation output (usually a square wave signal on the device) and adjust the probe's compensation trimmer until a flat-top square wave is displayed on the screen.

6. Osnovno delovanje

6.1 Način osciloskopa

The FNIRSI-1014D operates primarily as a dual-channel digital oscilloscope. The main display shows the waveforms, measurement parameters, and control settings.

• Vertikalni nadzor: Use the CH1/CH2 buttons and associated rotary encoders to adjust vertical position and voltage scale (Volts/Div) for each channel.
• Horizontalne kontrole: Use the TIME/DIV rotary encoder to adjust the horizontal time base.
• Nastavitve sprožilca: The 'EDGE' button allows selection of rising or falling edge trigger. 'MODE' button selects trigger mode (Auto, Normal, Single).
• Gumb AUTO: Pressing the 'AUTO' button automatically adjusts the vertical and horizontal settings to display a stable waveform.
• Merilne funkcije: The device supports various automatic measurements. Refer to the on-screen menu for available parameters.

6.2 Signal Generator Mode

The FNIRSI-1014D includes a built-in 10MHz DDS signal generator capable of producing 14 types of waveforms.

• Activating Generator: Press the 'GEN' button to access the signal generator functions.
• Izbira valovne oblike: Use the navigation buttons to select the desired waveform type (e.g., Sine, Square, Triangle).
• Frekvenca/AmpPrilagoditev višine: Use the rotary encoders to set the frequency and amplitude of the generated signal.
• Izhodna povezava: Connect the signal generator output (typically a dedicated BNC port or shared with CH2 in generator mode) to the circuit or device under test.

7. Vzdrževanje

• Čiščenje: Za čiščenje zunanjosti naprave uporabite mehko, suho krpo. Za trdovratno umazanijo rahlo obrišiteamp Uporabite lahko krpo z blagim detergentom, pri čemer pazite, da v napravo ne pride tekočina.
• Shranjevanje: Napravo shranjujte na hladnem in suhem mestu, stran od neposredne sončne svetlobe in ekstremnih temperatur, ko je ne uporabljate.
• Skrb za sondo: Handle probes carefully. Avoid bending or stressing the cables. Keep probe tips clean.
• Baterija (če je primerno): If the device has an internal rechargeable battery, follow manufacturer guidelines for charging and storage to prolong battery life.

8. Odpravljanje težav

• Brez napajanja:
  • Ensure the power adapter is correctly connected and the power outlet is functional.
  • Check the power button for proper engagement.
• Brez prikaza valovne oblike:
  • Verify probes are correctly connected to the input channels and the signal source.
  • Adjust the vertical (Volts/Div) and horizontal (Time/Div) scales.
  • Check trigger settings (Mode, Level, Edge). Try pressing the 'AUTO' button.
  • Ensure the input coupling (AC/DC) is appropriate for the signal.
• Popačena valovna oblika:
  • Izvedite kompenzacijo sonde.
  • Check for proper grounding of the device and the circuit under test.
  • Ensure the signal amplitude does not exceed the input range of the oscilloscope.
