The Philips PM5540 is a test pattern generator that could be considered a black & white predecessor of the widely used Philips PM5544 test pattern. It has been used in Australia, Abu Dhabi, Denmark, Israel, Qatar and the Netherlands. A heavily modified version of the PM5540 test card was used by Sjónvarpið of Iceland from 1966 until 1982.
