Briefs: Anritsu enhances test device

Anritsu will unveil during this week's International Wireless Communications Expo an upgraded version of its LMR Master S412E system analyzer that supports Project 25 Phase 2, as well as positive train control.

"This is the only piece of test equipment in the world that supports positive train control," said David Witkowski, a senior product manager for Anritsu (booth 813).

Positive train control, or PTC, was mandated by the Rail Safety and Improvement Act of 2008. The technology monitors the location of freight and commuter trains in order to keep them from colliding. Congress set a deadline of Dec. 31, 2015, for its implementation.

According Witkowski, PTC is a real challenge for railways. First, PTC radios are relatively new and are still in the process of being field-proven, he said. Second, PTC sensors will need to be installed along roughly 65,000 miles of track, many of which are in desolate, rugged or hostile areas. Third, the clock is ticking.

That's why Anritsu decided to add PTC support to the S412E, according to Witkowski.

"Until now, there wasn't even bench-top equipment available to do this type of testing," he said. "But with the amount of running around they're going to have to do, they're going to need a portable tester."
