4. Podešavanje

1. Priključak za napajanje: Connect the provided 110-230V wide voltage-power line to the oscilloscope's power input and a suitable power outlet.

2. Povezivanje sonde: Connect the oscilloscope probes to the desired input channels (1, 2, 3, or 4) on the front panel. Ensure a secure connection.

3. Signal Generator Connection (Optional): If using the integrated signal generator, connect the signal output line (BNC to BNC) from the 'Gen Out' port to the device under test or an oscilloscope input channel for monitoring.

4. USB priključak (opciono): For PC communication or system updates, connect the USB communication line from the oscilloscope's USB port to your computer.

5. Uključeno: Press the recessed power button located on the front panel. You may need to use a fingernail to fully engage the button.

6. Kalibracija sonde: Before taking measurements, it is recommended to calibrate all four probes. Connect a probe to the calibrator output (1kHz, 1V) on the front panel and adjust the probe compensation for a flat-top square wave display.

5. Uputstvo za upotrebu

5.1. Basic Oscilloscope Operation

• Vertikalne kontrole: Use the vertical knobs for each channel (1-4) to adjust the voltage scale (V/div) and vertical position of the waveform.
• Horizontalne kontrole: Use the horizontal knobs to adjust the time base (s/div) and horizontal position of the waveform.
• Sistem okidanja: 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.
• Automatsko skaliranje: 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.

5.3. Funkcije mjerenja

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

5.4. Waveform Generator

The integrated waveform generator can produce various signal types:

• Sinusni talas
• Kvadratni talas
• Ramp (Triangular/Trapezoidal)
• Puls
• Buka
• 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

• USB pohrana: The oscilloscope supports U-stick storage for saving waveforms, settings, and screenshots. Insert a USB flash drive into the front panel USB host port.
• Ažuriranje sistema: Firmware updates can be performed via the USB device port. Refer to the official Hantek webstranica za najnoviji firmver i upute.

6. Održavanje

• čišćenje: Use a soft, dry cloth to clean the exterior of the oscilloscope. Do not use abrasive cleaners or solvents.
• Skladištenje: Store the oscilloscope in a dry, dust-free environment when not in use.
• Ažuriranja softvera: Redovno provjeravajte proizvođačeve webstranica za ažuriranja firmvera kako bi se osigurale optimalne performanse i pristup novim funkcijama.

7. Otkrivanje problema

• Nema napajanja: Ensure the power cable is securely connected to both the oscilloscope and a working power outlet. Check the power button is fully pressed.
• Nema prikaza talasnog oblika: Verify probes are correctly connected to the input channels and the device under test. Check the vertical and horizontal scale settings, and ensure the trigger is properly configured or use the 'Auto Scale' function.
• Problemi sa softverom: If experiencing issues with PC communication or custom waveform generation software, ensure all required drivers and libraries are installed. Compatibility issues with older operating systems (e.g., Windows 7) may occur.
• Netačna mjerenja: Perform probe calibration as described in the Setup section.
