The uniquely designed Bus Isolation Extenders are innovative tools for developing and testing of PC add-on boards. They allow the board under test to be added and removed from the system bus, without having to power down the entire system. They offer tremendous time and labor savings during product development and production testing. In addition, we offer wearout extenders, to help protect the connector on the Bus Isolation Extender from being worn out during repeated testing. Our extender connectors are made of heavy duty material for more insertion cycles. In today's fast moving computer market, products are utilized with shorter life cycles than ever before. It would not be cost effective to develop special functional test systems for each application. Therefore, the bus isolation extender is the wisest alternative for functional testing, without having to use expensive setups.
