5.1 Повезивање напајања
Connect the provided USB cable to the DC 5V input port on the side of the function generator and to a suitable USB power source (e.g., a computer USB port, a USB wall adapter).
Figure 1: ASHATA FG-100 DDS Function Generator connected via USB cable.
5.2 Почетно укључивање
Once power is connected, the device will automatically power on, and the LCD display will illuminate, showing the current waveform function and frequency.
6. Упутство за употребу
6.1 Интерфаце Оверview
The front panel of the FG-100 features an LCD display, several buttons for control, and an amplitude adjustment knob. The output is provided via a BNC connector.
Figure 2: Front panel controls and display of the FG-100.
6.2 Selecting Waveforms
Притисните тастер МОДЕ button to cycle through the available waveform types: Sine, Square, Triangle, Forward Sawtooth, Reverse Sawtooth, Pulse, and ECG. The selected waveform will be displayed on the LCD.
6.3 Adjusting Frequency
Користите ЦУРСОР button to select the digit you wish to adjust. Then, use the + и - buttons to increase or decrease the frequency value. The frequency range for sine waves is 1Hz to 500kHz (amplitude flat up to 200kHz), and for other waveforms, it is 1Hz to 20kHz for optimal phase noise and distortion.
6.4 Подешавање Amplitude and DC Offset
- Ampсветлост (AMP): Ротирајте AMP knob on the right side of the device to adjust the output waveform amplitude. The maximum output amplitude is ±10V (peak-to-peak).
- ДЦ Оффсет: Користите DC OFFSET switch (ON/OFF) and the associated knob to apply or adjust a DC bias to the waveform. The maximum DC offset is ±10V.
6.5 Using the Filter
Притисните тастер ФИЛТЕР button to toggle the internal filter on or off. This filter is designed for sine and pulse waveforms.
6.6 Outputting Waveforms
Притисните тастер РУН / СТОП button to start or stop the waveform output. When running, the waveform will be generated at the ОУТ БНЦ конектор.
