  • Input Stage:
    • Input Connector: The oscilloscope typically has one or more input channels, each equipped with a BNC (Bayonet Neill-Concelman) or other connectors for attaching probe leads.
    • Attenuators: These are used to adjust the voltage level of the incoming signal to prevent damage to the oscilloscope.
  • Analog-to-Digital Converter (ADC):
    • The analogy signal from the input stage is converted into a digital signal using an ADC. The ADC samples the input waveform at regular intervals and quantizes the voltage levels.
  • Memory:
    • GAO Tek’s Digital oscilloscopes have internal memory to store the digitized waveform data. The size of the memory determines the duration of the waveform that can be captured and displayed.
  • Processor:
    • A powerful processor is used to perform various calculations and manipulations on the digitized waveform data. This includes tasks such as signal processing, triggering, and display rendering.
  • Display:
    • GAO’s digital oscilloscope display is a crucial component, usually an LCD or LED screen. It visualizes the waveform data and provides user interfaces for control and measurement.
  • User Interface:
    • Our digital Oscilloscopes have knobs, buttons, and a touchscreen interface for user control. These interfaces allow users to adjust settings such as time base, voltage scale, triggering, and more.
  • Triggering System:
    • The triggering system is responsible for initiating the capture of waveforms at specific points in time. It helps stabilize and synchronize the displayed waveform.
  • Signal Conditioning:
    • Some oscilloscopes may have additional signal conditioning components like amplifiers and filters to enhance the quality of the captured signals.
  • Power Supply:
    • GAO Tek’s digital ooscilloscopes require a power supply to operate. This can be an internal power supply or an external power source, depending on the model and design.
  • Communication Ports:
    • USB, ethernet, and other communication ports are often included to facilitate data transfer between the oscilloscope and external devices, such as computers or printers.
  • Calibration Components:
    • GAO’s digital ooscilloscopes have built-in calibration components to ensure accurate measurements. This may include reference voltage sources and calibration routines.
  • Cooling System:
    • In some cases, especially for high-performance oscilloscopes, a cooling system may be employed to dissipate heat generated during operation.
