## Description

Compact DDS generator for fast testing and troubleshooting in electronics, with LCD1602 display and dedicated controls for easy setup. Offers 1Hz-500kHz frequency with fine resolution, multiple waveforms including sine, square, triangle, saw and noise, plus DC offset and FILTER function for cleaner signal. 50 Ohm output, 4-10V power supply, memorable settings.
DDS signal generator module, FG-100, with housing, assembled, designed for testing, measuring and quick troubleshooting in electronics.
The plastic housing and small dimensions make it easy to transport, and operation is simple thanks to the LCD1602 display and dedicated buttons for waveform selection, frequency adjustment and on/off.
It generates several useful waveforms in the lab, including sine, square, triangle, forward and reverse sawtooth, plus special signals such as ECG and noise, making it suitable for checking impulse response, characterizing audio amplifiers, and adjusting oscilloscopes.
Due to its good frequency stability and fine resolution, it can also be used to calibrate the oscilloscope time base, and the ability to memorize settings helps to quickly repeat tests. Includes 50 Ohm impedance output, DC offset support and flexible power supply from adapter or Li-ion battery.
Includes DC offset function to shift the signal up or down from 0 V when you need input bias, as well as FILTER function that cleans the waveform by reducing harmonics and noise, especially useful for sine signals for more accurate measurements.
Requires BNC cable (available separately) to connect output. This is NOT INCLUDED!

Use:
Power the device via the USB cable to a 5VDC phone charger and press POWER to turn it on.
Connect the BNC Cable to the output (OUT). This is not included and must be purchased separately.
Press MODE to select the desired waveform.
Use the CURSOR to choose the digit that changes to the frequency, then adjust with the plus and minus buttons.
Press RUN STOP to start or stop the signal output.
For DC offset, activate the function in the dedicated area and adjust the level on the potentiometer within the allowed limits, then check the signal on the oscilloscope before connecting to the circuit.
For stable measurements, use short cables, firm connections, and avoid connecting to inappropriate loads if you want maximum amplitude without load.
Control Interface:
Button or control | Function | Observations
POWER | Starts or stops the generator | At startup, the current settings appear on the screen
modeller | Change the waveform | Switch between sine, square, triangle, sawtooth and other available shapes
CURSOR | Move the cursor to the parameter or digit that is being changed. | When the cursor is blinking you can change the value with + and -
+ | Increases the selected value | Increases the frequency or value of the selected digit
- | Decreases the selected value | Decreases the frequency or value of the selected digit
RUN STOP | Turns the signal output on or off. | When the output is off, there is no signal at OUT.
DC OFFSET ON OFF | Enables or disables the DC voltage component. | When ON, the signal is shifted from 0 V.
DC OFFSET adjustment, rotary knob | Adjust the offset level | Moves the signal up or down within the limits of the device
FILTER | Enables or disables signal filtering. | Helps with a cleaner sine, can slightly reduce amplitude at some frequencies
AMP | Toggle amplitude adjustment | allows adjustment of the output amplitude level
OUT, output connector | Output of the generated signal | Connect the BNC cable here
