This Active Extender board allows HOT SWAPPING or LIVE INSERTION of the Unit-Under-Test into the AGP bus.
The “HOT SWAPPING” feature of this extender eliminates the need for turning the PC Off and On and repeated
rebooting. This feature speeds up rework, characterization and test of Unit-Under-Test in the development phase as
well as production test. The elimination of the repeated power cycling also helps prolong the system life and the hard
disc operation. This Active Extender uses a new CMOS technology for switching the signals On and Off (known as
“Quick Switch”). These switches have a very fast propagation delay, typically about 250 picoseconds, resulting in no
timing degradation between the bus and the Unit-Under-Test. The switches are also bi-directional allowing the entire
address range to be supported for both target and master type operation. Active Extender
