Signal Generation Circuitry: GAO’s signal generation circuitry is the core component responsible for generating the electrical signals. It typically consists of operational amplifiers, digital-to-analog converters (DACs), oscillators, and waveform shaping circuits. Our circuitry is designed to produce precise waveforms with adjustable frequency, amplitude, and phase. 

Microcontroller or Microprocessor: GAO’s modern function generators often incorporate microcontrollers or microprocessors for signal processing, user interface control, and waveform manipulation. Our processors handle tasks such as frequency tuning, waveform selection, modulation, and interfacing with external devices. 

User Interface: Our function generators feature a user interface for controlling various parameters such as frequency, amplitude, waveform type, and modulation settings. Our interface may include a keypad, knobs, buttons, switches, and a graphical display (LCD or LED) for user interaction and feedback. 

Digital Signal Processing (DSP) Unit: Some of our advanced function generators employ DSP units for signal processing tasks like waveform synthesis, modulation, filtering, and distortion correction. Our DSP units enhance the versatility and accuracy of generated waveforms. 

Memory: GAO Tek function generators often include memory modules to store user-defined waveforms, modulation patterns, and instrument settings. This allows users to recall and reuse specific configurations without manual adjustment. 

Clock Generator: Our precise clock generator is essential for generating stable and accurate waveforms. It provides the reference frequency for the oscillator circuits, ensuring consistent waveform generation across different frequencies and time intervals. 

Output Amplifiers: Our amplifiers boost the signal generated by the signal generation circuitry to the desired amplitude level. Output amplifiers may include voltage amplifiers, current amplifiers, and impedance matching circuits to drive external loads efficiently. 

Power Supply Unit: GAO Tek function generators require a stable and clean power supply to operate reliably. Our power supply unit supplies regulated DC voltages to various components within the device, ensuring consistent performance and signal integrity. 

Connectors and Interfaces: Our function generators feature various input and output connectors for interfacing with external devices and test setups. Our common connectors include BNC connectors for signal output, trigger input, modulation input, and external frequency reference input. 

Mechanical Enclosure: Our enclosure houses all the electronic components and provides physical protection to the internal circuitry. It may also incorporate cooling mechanisms such as fans or heat sinks to dissipate heat generated during operation.Â
