Reprinted from an ItWorks press release:

ItWorks recently released the CALIBUG–a pocket USB tool that can generate as many as 100 video test patterns. The CALIBUG also turns any PC or laptop equipped with Composite/YC video outputs into an NTSC video test signal generator: rivaling those that cost thousands of dollars.

Designed with input from a team of video professionals (including a former TV station Chief Engineer and a Multimedia Producer), the CALIBUG is a complete set of video reference tools, measurement aids, video and audio tests, and multimedia content designed to help you tune your NTSC composite video system to its full potential. All this, plus the convenience of having a device that clips onto your belt or slides into your pocket to take anywhere!
