Bus Extender Aids AGP Card Designers

The AGPEX4 accelerated graphics port (AGP) bus extender features pluggable fuses, power-indicating LEDs, header pins for logic analyzer hook-up and an optional right-angle AGP connector on the component side. By changing the position of the pluggable fuses, an AGP board on top of the AGPEX4 extender can be powered from the motherboard or from an external source by means of terminal blocks. As a result, voltage margin measurements can be performed through an external power source and current measurement can be performed by removing the fuse and bridging the fuseholder with an ammeter. AGPEX4-S is for standard AGP form factors that fit into PC-AT chassis, and AGPEX4-N is for NLX form factors. There also are right-angle versions.
