Test Card G
Test Card G was a television test card broadcast occasionally by the BBC. It was the first electronically generated test card to be broadcast, and was a variant of the Philips PM5544 test pattern.
Another Test Card G, unrelated, was developed by Pye as a variant on Test Card C. It was used in other countries that use 625-line PAL, but probably not in Britain.
