5. Guia de configuració
5.1 Connexió de potència
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 Encès inicial
Once power is connected, the device will automatically power on, and the LCD display will illuminate, showing the current waveform function and frequency.
6. Instruccions de funcionament
6.1 S'ha acabat la interfícieview
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
Premeu el botó MODE 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
Utilitza el CURSOR button to select the digit you wish to adjust. Then, use the + i - 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 Ajust Amplitude and DC Offset
- Amplitud (AMP): Gira el AMP knob on the right side of the device to adjust the output waveform amplitude. The maximum output amplitude is ±10V (peak-to-peak).
- Offset DC: Utilitza el DESPLAÇAMENT DE CC 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
Premeu el botó FILTRE button to toggle the internal filter on or off. This filter is designed for sine and pulse waveforms.
6.6 Outputting Waveforms
Premeu el botó CARRER/PARAR button to start or stop the waveform output. When running, the waveform will be generated at the FORA Connector BNC.
