1. Introduction
The FeelTech FY1100 Series is a single-channel DDS (Direct Digital Synthesis) signal generator designed for producing accurate, stable, and low-distortion output signals. It features a user-friendly interface with a 2.4-inch TFT color LCD screen (320x240 pixels) that simultaneously displays output signal parameters and current key functions. This instrument is ideal for various applications requiring precise waveform generation, including electronic circuit testing, education, and research.

- Power On: Press the power button on the front panel to turn on the device. The LCD screen will illuminate.
4. Operation
The FY1100 Series signal generator is designed for intuitive operation. The front panel features a display, function buttons, a rotary encoder, and output connectors.
4.1 Front Panel Controls
- Display Screen: Shows waveform parameters, frequency, amplitude, offset, duty cycle, and current function prompts.
- Function Buttons: Dedicated buttons for SWEEP, BURST, SYSTEM settings, and waveform selection (Sine, Square, Triangle, etc.).
- Rotary Encoder: Used to adjust parameter values. Turn clockwise to increase, counter-clockwise to decrease. Press to confirm selection or enter a menu.
- ON/OFF CH1 Button: Toggles the main channel 1 output.
- TTL Output: Dedicated BNC connector for TTL level output.
- Counter Input: BNC connector for frequency counting functions.
4.2 Generating a Waveform
- Select Waveform: Press the desired waveform button (e.g., Sine, Square) to select the output waveform type.
- Adjust Frequency: Use the rotary encoder to set the desired frequency. The display will show the current frequency.
- Adjust Amplitude: Use the amplitude control (often a dedicated button or menu option accessed via the rotary encoder) to set the peak-to-peak voltage.
- Adjust Offset (DC Bias): If needed, adjust the DC offset using the corresponding control. The range is -7.5V to +7.5V.
- Adjust Duty Cycle: For Square and COMS waves, you can adjust the duty cycle using the dedicated control or menu option.
- Enable Output: Press the ON/OFF CH1 button to enable the signal output on Channel 1.
- Connect to Device: Connect the BNC output of Channel 1 to your testing circuit or oscilloscope.
5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your signal generator.
- Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use abrasive cleaners or solvents.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Ventilation: Ensure the ventilation slots are not obstructed to prevent overheating.
- Power Supply: Always use the original or a compatible 5V DC power adapter.
6. Troubleshooting
If you encounter issues with your signal generator, refer to the following common problems and solutions:
- No Power:
- Check if the power adapter is securely connected to both the device and the power outlet.
- Verify the power outlet is functional.
- Ensure the power button is pressed.
- No Output Signal:
- Confirm that the ON/OFF CH1 button is activated (output enabled).
- Check the connection cable from the signal generator to your testing equipment.
- Verify that the amplitude is set to a non-zero value.
- Ensure the frequency is within the operational range.
- Incorrect Waveform Display:
- Ensure the correct waveform type is selected.
- Check the settings for frequency, amplitude, and offset.
If the problem persists, please contact customer support.
