The Philips PM5540 was an early electronic video signal generator, which generated a monochrome test card [3] that is considered to be a black-and-white predecessor of the widely used Philips PM5544 and the latter's related family of Philips circle test patterns.
When the circle generator fails, in some cases it can show this exact pattern. Alternatively if it is removed or disconnected from the unit, once again it will output this pattern. I am slightly concerned this page has spread a lot of myth about a non-existent variation which in reality may have been a recording of a 5544/34 which went bad, and ...

Instead, a circle of the same radius needs a different determinant, to allow the curve to come in slightly closer to the center or extend out farther.
