5. Podešavanje
To set up your FG-300 Signal Generator, follow these simple steps:
- Raspakirajte: Pažljivo izvadite sve komponente iz pakovanja.
- Priključite napajanje: Connect the provided USB data cable to the USB port on the FG-300 device. Plug the other end of the USB cable into a compatible 5V USB power source (e.g., a computer USB port, a USB wall adapter, or a power bank).
- Uključeno: The device should power on automatically or can be activated by pressing the power button. Refer to the 'Operating Instructions' section for details on screen activation.
6. Uputstvo za upotrebu
This section details how to operate your FG-300 Signal Generator, including power management, frequency adjustment, and waveform selection.
6.1. Power Management and Screen Control

slika: An important notice outlining the device's screen-off modes, manual activation, and how to distinguish between auto-screen-off and full shutdown.
- Auto-Screen-Off Mode (Power-Saving): The device's system will automatically enter screen auto-off mode after 2 minutes of inactivity. The device continues to operate normally in the background.
- Screen-On Mode (Manual Activation): Press the power button once to wake up and light up the screen. Pressing it again will turn off the screen, but the device remains operational.
- Distinguishing Auto-Screen-Off vs. Shutdown:
- Press the power button once. If the screen lights up, the device was in auto-screen-off mode.
- If the screen remains dark, the device has powered off.
- Flashing signal lights on both sides of the device indicate it is still operating (if the flashing signal light has been set to turn on, F02-F09).
- Isključivanje: In powered-on mode, hold the power button for 3 seconds to shut down the device.
6.2. Podešavanje frekvencije
The FG-300 allows for precise frequency adjustment across a broad range.
- Frekvencijski raspon: The adjustable frequency range is 0.01 Hz to 200,000 Hz.
- Zadana frekvencija: The default Schumann resonance frequency is 7.83 Hz.
- Unapred podešene frekvencije: The device can also be adjusted to specific higher frequencies such as 174 Hz, 285 Hz, 396 Hz, 417 Hz, 528 Hz, 639 Hz, 741 Hz, 852 Hz, and 963 Hz.
- Podešavanje: Use the keypad and display interface to input and set the desired frequency. Refer to the on-screen prompts for navigation.
6.3. Odabir talasnog oblika
The FG-300 supports multiple waveform outputs to suit various applications.

slika: A visual representation of the multiple waveform outputs available from the device, including sine, square, triangle, forward sawtooth, reverse sawtooth, ECG, half wave, Lorentz, Gauss, Singer, exponential rise, exponential fall, and 7.83Hz for Schumann wave.
- Dostupni talasni oblici: Sine wave, square wave, and chamfered square wave.
- Izbor: Use the device's interface to select the desired waveform. The display will show the currently active waveform.
- Izlaz Amplitudes: Sine wave signal voltage amplitude is approximately 3 V. Square wave signal voltage amplitude is approximately 5 V.
7. Održavanje
Proper maintenance ensures the longevity and optimal performance of your FG-300 Signal Generator.
- čišćenje: Use a soft, dry cloth to clean the device's exterior. Do not use liquid cleaners or solvents, as they may damage the acrylic case or internal components.
- Skladištenje: Kada se ne koristi, uređaj čuvajte na hladnom i suhom mjestu, dalje od direktne sunčeve svjetlosti i ekstremnih temperatura.
