5. Nastavení

Follow these steps to set up your FG-100 Function Generator:

  1. Připojení napájení: Connect the provided USB power cable to the 'DC 5V' input port on the side of the FG-100. Plug the other end of the USB cable into a 5V USB power adapter (not included) or a compatible USB port.
  2. Výstupní připojení: Connect a BNC cable (not included) to the 'OUT' BNC connector on the side of the FG-100. Connect the other end of the BNC cable to your oscilloscope, frequency counter, or other test equipment.
  3. Zapnutí: Press the 'POWER' button on the front panel. The LCD display should illuminate and show the default waveform and frequency.

6. Návod k obsluze

6.1 Výběr průběhu

Press the 'MODE' button to cycle through the available waveform types: Sine, Square, Triangle, and Sawtooth. The currently selected waveform will be displayed on the LCD.

6.2 Nastavení frekvence

To adjust the output frequency:

  1. The frequency value is displayed on the LCD.
  2. Press the 'CURSOR' button to move the blinking cursor to the digit you wish to change.
  3. Use the '+' and '-' buttons to increase or decrease the value of the selected digit.
  4. Repeat steps 2 and 3 until the desired frequency is set.

6.3 DC Offset Control

The 'DC OFFSET' switch allows you to add or remove a DC component to the output signal. Flip the switch to 'ON' to enable DC offset or 'OFF' to disable it.

6.4 Filter Function

Press the 'FILTER' button to toggle the output filter. This filter can be used to smooth the output of sine and pulse waves, which may be beneficial for certain applications.

6.5 Amplitude Adjustment

Rotate the 'AMP' knob on the side of the device to adjust the amplitude (peak-to-peak voltage) of the output signal. Turn clockwise to increase amplitude, counter-clockwise to decrease.

6.6 Run/Stop Output

Press the 'RUN/STOP' button to pause or resume the waveform output. When paused, the output signal will cease, and the display may indicate a stopped state.

7. Údržba

Proper maintenance ensures the longevity and reliable operation of your FG-100.

  • Čištění: Regularly wipe the device with a soft, dry, lint-free cloth. Do not use abrasive cleaners, solvents, or chemical agents.
  • Skladování: Pokud zařízení nepoužíváte, skladujte jej na chladném a suchém místě, mimo dosah přímého slunečního záření a nadměrného prachu.
  • Inspekce: Periodically inspect the power cable and connectors for any signs of damage. If damage is found, discontinue use and contact support.

8. Řešení problémů

If you encounter issues with your FG-100, refer to the following common problems and solutions:

ProblémMožná příčinaŘešení
Device does not power on / LCD is blank.No power, faulty cable, or power adapter issue.Ensure the USB power cable is securely connected. Try a different USB power adapter or USB port. Verify the 'POWER' button is pressed.
