Extender boards are electronic circuit boards used to bring a circuit card out of an enclosure or card cage so it can be tested or debugged.
How do extender boards work?
Extender boards work by extending signals from the motherboard for testing or debugging purposes. Most of them offer access to the bus signals (bundles of wire held together) through marked probe points, while some utilise multi-layer technology to control cross talk (unwanted transfer of signals between communication channels) and signal distortions.
Extender boards and their relevant adapters come in a wide array of options that support different form factor variations, ranging from Eurocards to Accelerated Graphic Ports (AGPs).
What are
extender
boards used for?
Extender boards are commonly used in highly integrated applications, such as:
Medical equipment, night-vision systems and industrial monitoring requiring enhanced graphics capabilities
Shipboard systems for high definition displays and target tracking
Mission management, integrated display processing and navigational control of avionics systems
Applications requiring a mix of enhanced graphics, I/O (Input/Output) options and high compute density.
