Below are general answers on typical components of a function generator from the list of GAO Tek’s function generator. To facilitate our customers to select our products, we have further classified our function generators by their features:  benchtop, direct digital synthesis (DDS), saved settings, handheld, and rugged.

We have products in stock and can ship overnight to most places in the U.S. and Canada.

Oscillator Circuit:

  • Voltage-Controlled Oscillator (VCO): The heart of GAO’s function generator produces an oscillating voltage signal. The frequency of the signal is adjustable and determines the output waveform.

Waveform Generation Circuitry:

  • Waveform Shaping Circuits: These circuits in our function generators shape the basic oscillating signal into various waveforms such as sine, square, triangle, sawtooth, and pulse. The user can select the desired waveform.

Frequency Control:

  • Frequency Control Knob: Allows users of GAO Tek function generators to manually adjust the frequency of the output waveform.
  • Digital Frequency Control: In modern our function generators, digital controls may be used for precise frequency adjustment.

Amplitude Control:

  • Amplitude Control Knob: Adjusts the amplitude or voltage level of the generated waveform.
  • Digital Amplitude Control: Some GAO’s function generators offer digital controls for precise amplitude adjustments.

Function Selector:

  • Function Selector Switch: Enables users to choose the desired waveform (sine, square, triangle, etc.) from the available options in our function generators.

Display:

  • Frequency Display: Some function generators feature a digital display that shows the current frequency of the output waveform.
  • Amplitude Display: Displays the amplitude of the generated waveform.

Modulation Controls:

  • Modulation Input: Allows external modulation sources to modulate the frequency or amplitude of the generated waveform.
  • Modulation Controls: Knobs or buttons for adjusting modulation parameters like depth and frequency.

Sweep Controls:

  • Sweep Input: Accepts an external signal to control the frequency sweep of the generated waveform.
  • Sweep Controls: Knobs or buttons for adjusting sweep parameters like start and stop frequencies.

Output Section:

  • Output Terminals: Connect to external circuits for signal injection or testing in GAO Tek function generators.
  • Attenuator: Allows for further adjustment of the output amplitude.

Triggering Options:

  • Trigger Input: Accepts an external trigger signal to synchronize the function generator with other instruments.
  • Trigger Output: Provides a trigger signal for synchronizing other instruments with our function generator.

Digital Interface:

  • USB, LAN, GPIB Ports: Allow remote control and data transfer capabilities for integration with computer-based systems in GAO Tek’s function generators.
  • Software Control: Some of our generators can be controlled and programmed using dedicated software.

Power Supply:

  • AC/DC Power Input: Our function generators can be powered by AC mains or DC power sources, depending on the model.

Mechanical Enclosure:

  • Chassis and Housing: Protect the internal components of our function generators and provide a durable and stable physical structure.

Cooling System:

  • Fan: Some function generators may include a cooling fan to dissipate heat generated during operation.

Safety Features:

  • Overload Protection: Protects GAO Tek’s function generator and connected devices from excessive currents or voltages.

Short Circuit Protection: Prevents damage in case of a short circuit.
