Here’s The Idea Behind Our ™ Concepts! Subampability Subampability™ (sub-amp-ability). noun: The ability to use an amplifier individually, or : as a building block, upon which power can be added incrementally. Grow as you go. One small step at a time. Building on what’s already there. AR has applied this age-old idea to amplifiers used for EMC testing. When you need a more powerful amplifier, now you can add the power, instead of tossing out the old amp and starting all over again. Add Power To Existing Amps. With test specs constantly changing, it’s an idea whose time has come. Many amplifiers within our “S” and “W” Series are designed so that the power can be expanded with a relatively simple upgrade. Of course, the amplifiers can still be used individually when needed. The latest examples are Models 10S4G11A (10 watts, 4-10.6 GHz) and 15S4G8A (15 watts 4-8 GHz). A fairly simple upgrade performed by AR expands the 10S4G11A to a 20S4G11A (20 watt, 4-10.6 GHz) … and the 15S4G8A to a 35S4G8A (35 watts, 4-8 GHz). Once this initial upgrade is performed, the sky’s the limit. The 20S4G11A and the 35S4G8A are like building blocks that can easily be expanded by adding sub amps and controller/combiner units. At AR, we’re always thinking ahead. And we know you are, too. That’s why you’ll appreciate our Subampability concept … and the fact that all AR products are backed by the strongest, most comprehensive warranty in the industry, and a global support system that's second to none.
