Super fast testing with the WireScope Pro LAN Cabling Tester Agilent’s WireScope Pro tester sweeps a full 1GHz in a few seconds, boosting your test speed to new industry leading Cat 6A and Cat 7 autotest times of 9 seconds. It also accelerates your copper and fiber testing with dual- wavelength fiber probes, the elimination of field calibration, and a new auto-increment capability. The WireScope Pro tester is the only handheld to provide Alien Crosstalk (AXT) measurements simultaneously on multiple ‘exciter’ cables, as well as produce final results on the spot, so you can quickly handle any future AXT field testing requirements. Alternative approaches could take hours to complete and require PC post processing to see the results. With simple software upgrades and a robust hardware platform operating at 1 GHz frequency, you’ll save on the cost of test because you’ll stay state-of-the-art for many years, eliminating the need to buy new testers every year or two. u.s. 1-800-829-4444, ext. 5465 Experience the speed of the WireScope Pro tester now at canada 1-877-894-4414, ext. 5465 www.agilent.com/find/wirescope or by talking to one of our ______________________ www.agilent.com/find/wirescope __________________________ engineers by calling our 800 #s. © Agilent Technologies, Inc. 2006 C Previous Page A Installation 7Maintenance Contents Zoom In Zoom Out Front Cover Search Issue B Next Page EMaGS F
