Spirent GSS7725

Generate, Understand, and Protect Against RF Interference

Whether you’re designing a global navigation satellite system (GNSS) chipset, or integrating a receiver into a device, RF interference can undermine positioning performance and compromise user experience.The Spirent GSS7725 is designed to let you quickly playback RF interference signals, under fully repeatable, lab conditions. Combined with a GNSS simulator, it will help you:

• Understand exactly how your product will respond to RF interference

• Test RF interference’s impact on product performance

• Prepare for a positive user experience and product success

RF Interference—a Growing Threat

RF interference—whether naturally occurring in the atmosphere, man-made but accidental, or created deliberately with low-cost RF jamming devices—is a serious and mounting threat to GNSS performance.And as more products and industries grow to depend on accurate, robust GNSS positioning and timing, its potential to cause damage grows: from driving dissatisfied users

to return their mobile devices, to compromising critical infrastructure, and risking network failures.

Introducing GSS7725

The Spirent GSS7725 is a dedicated RF interference generator that turns I/Q files into interference signals.Combined with a GNSS simulator, the GSS7725 lets you test your chipset or device in a variety of different interference environments, under controlled, repeatable conditions.

Unlike other standalone interference generators, the GSS7725 seamlessly integrates with Spirent GNSS simulators, test packs and automation tool. And with a competitive price point, it’s ideal for commercial enterprises looking for a simpler way to test for GNSS interference—without going over budget
