Aeroflex has enhanced its model 3550 digital radio test system with the addition of enhanced VSWR and distance to fault functionality to the tracking generator. By utilizing the sweep of the tracking generator, the 3550 can measure and display the VSWR of an antenna or find the location of one or more faults in a cable. This enhanced capability, combined with all of the other, expansive radio test capabilities of the 3550, make it the ideal choice for testing radio systems, whether on the bench, in a vehicle or at a site. www.aeroflex.com
