who we are and what we do at xsubc electronics, llc ("xsubc"), we feel that despite over a century of continuous evolution and development, there are still significant deficiencies in affordable communications equipment and test instruments. the gap between the high cost and limited features in some equipment has lead us to coin the phrase 'the price - performance divide', and the deficiencies that we see don't just revolve around how much performance you get for the price you pay, but also the limitations of the equipment itself. with that in mind, xsubc attempts to fill those voids left behind by others. xsubc (pronounced "eks-sub-see", the mathematical expression of an 'x' followed by a subscript letter 'c'), based in new jersey, usa, was founded by an entrepreneurially spirited team in 2006 as an rf and dsp consulting, design, and manufacturing company. our mission is to design and manufacture a variety of innovative products, and as such become a significant force in the industry, differentiating us from our competition through price, performance, and quality. all of our products are designed and assembled in the usa.
