	Test card - Wikipedia, the free encyclopedia
		A test card, also known as a test pattern in North America, is a television test signal, typically broadcast at times when the transmitter is active, but no program is being broadcast (often at startup and closedown).
		The most famous British test card is Test Card F which incorporates a colour photograph of Carole Hersee (daughter of BBC engineer George Hersee) playing noughts and crosses with a doll, used on the BBC and ITV from the beginning of colour broadcasts in the late 1960s.
		Test card music became popular in its own right when a group of enthusiasts discovered one another and realised they were not alone in enjoying the music played during the day in the 1950s, 60s and 70s while the test card was broadcast on BBC.

	Test Card J - Wikipedia, the free encyclopedia
		Test Card J is a test card, an image used to determine the quality of a broadcast television picture.
		The centre picture was also re-aligned within Test Card J to put the cross on the noughts and crosses board at the exact centre of the screen.
		A green square at the top of the screen, which does not appear in Test Card F, is used within Test Card J to facilitate an easier observation of chrominance to luminance delay.

	Punch card - Encyclopedia.WorldSearch (Site not responding. Last check: 2007-10-20)
		Such cards were also used as an input method for the primitive calculating machines of the late 19th century.
		In that year, punched cards were made a standard size, exactly 7-3/8 inch by 3-1/4 inch (187.325 by 82.55 mm), reportedly corresponding to the US currency of the day, though some sources characterise this assertion as urban legend.
		In this binary mode, cards could be made in which every possible punch position had a hole: these were called "lace cards." For example, the IBM 700/7000 series scientific computers treated every row as two 36-bit words, in columns 1-72, ignoring the last 8 columns.

	Test Card W - Wikipedia, the free encyclopedia
		Test Card W is a test card, an image used to determine the quality of a broadcast television picture.
		It is an updated widescreen version of Test Card F (which was created by BBC engineer George Hersee), although it's based on the newer Test Card J.
		The last known occasion that this card was broadcast on British screens was Friday, 9 January 2004, when early morning tests were carried out on BBC One and BBC Two.

		Test Card F has castellations with arrows to enable the dealer to adjust the scan amplitudes and thus ensure that the picture just fills the screen whilst circles remain the correct shape.
		Test Cards D and E are an exception to this, having sinusoidal frequency gratings printed onto the slide.
		Test Card E had a further innovation - instead of a peak white border around the gratings it had one the same brightness as the peak of the sine waves, and each row of gratings started and ended at this brightness level.

	Television Test Cards, Tuning Signals, Clocks and Idents
		Of course special test generators were available that could be used to make accurate measurements of the performance of every aspect of the studio and distribution equipment, but again, how useful it would be to have a pattern that could give a rough indication of performance (or lack of it) from camera to screen.
		Test Card W (16:9) that included almost all the features of Test Card F, had the central colour picture digitally remastered from the original colour reversal transparency, and had additional tests required for digital operations.
		The intention was to use Test Card D on 405-lines and Test Card E on 625-lines, but BBC engineers were unhappy with the appearance of the TCE frequency gratings and so this card, which never sported an identification letter, was retained until the start of the colour service in July 1967.

		The replacement for test card E was this, a modified version of Test Card C. It was used on BBC 2 from its birth in 1964 until colour was introduced in 1967 and Test Card F took over.
		This early widescreen Test Card was broadcast by the BBC as part of digital tests on Astra 1D in mid March 1998.
		Test Card J has been broadcast on BBC2, Test Card W was shown on "Have I Got News For You" and on News 24 during the BBC Power Failure on 20th June 2000.

		Test Card F Fact: The green colour of the doll was artificially enhanced to help it test chrominance response (via the yellow buttons).
		The test card was shown for a few hours before the evening progmmes - mostly F, but various regions 'opted out' and showed G for a while, usually with different music.
		Test transmissions from Winter Hill, NW England, began in the winter of 1981-82, and on S4C from Moel-y-Parc, N Wales, in May 1982.

		Having obtained permission from BREMA, with whom we hold the joint copyright on the Test Card, Richard Russell at Kingswood has now re-created the 4x3 Test Card with the same re-scanned centre picture as was used in the widescreen Test Card W last year.
		This Test Card also has the full range greyscale with pairs of flashing dots as used in Test Card W, and the green chrom/lum delay square in the top streak-box.
		The Test Card fills the full width of the digital active line, and is thus 18 pixels (about 2.5%) wider than the traditional analogue active line.

	Device-under-test card for a burn-in board - Patent 5726482
		The device-under-test card also includes a discrete resistor or alternatively a resistor ladder that permits a terminal of a device-under-test to be coupled to a power or ground terminal or to any combination of resistances including a short, in addition or as an alternative to any one of various signal drivers and/or receivers.
		Traces in the DUT card also allow any terminal of a device-under-test to be connected to power and ground, and to drivers and/or receivers of signals, such as a predetermined test signal, or another signal, such as a clock signal, by appropriate programming of the matrix of fuses and/or antifuses.
		Any number of DUT cards, such as one, two, three or four or more, as appropriate, can be provided in a burn-in board depending on for example the number of terminals of a device-under-test.

	Not In Production: What's in a test card?
		Most of them are "Hey, here are some pictures of testcards!"-type places with very little technical information on how they work and what makes a good test card.
		While some people have long thought that George Hersee's classic Test Card F was about as perfect a test signal as it was possible to produce using a bunch of lines, some colours and a girl playing noughts and crosses, the digital revolution has changed this.
		The author worked with the BBC R&D department to update F for the digital age, and his detailed account of the pitfalls and problems encountered in creating both a standard 4:3 version (Test Card J) and, more complicatedly, a widescreen version (Test Card W) makes very interesting reading.

	The Test Card Gallery
		Used from the beginning of the BBC until the early seventies, the tuning signal was primarily for viewers to warm up their television sets and adjust the numerous controls until they could see an acceptable picture.
		The Test Cards were for testing of equipment throughout the full chain of transmission.
		From 1955 the ITA, and its successor the IBA used numerous test cards and tuning signals, some were variants of those used by the BBC, others like the classic "Picasso" tuning signal were entirely original.This section shows a selection of them.

		Here, a computer controlled axial fan is positioned at the outlet in order to draw air through the chamber, whilst a ventilation rate sensor measures the associated air velocity.
		Although initially constructed as a small scale representation of an agricultural building, the modelling and control problems that can be investigated using the environmental test chamber, apply across a wide range of scientific and engineering disciplines.
		To measure the airflow rate away from the outlet a second air velocity transducer is positioned inside the 3D-airspace.

	Sound Card Performance Test Techtalk THD
		THD typically requires measuring harmonics that are at higher frequencies than the test signal.
		If the test signal is at a high frequency, then many harmonics may be filtered out, later on in the process of handling the signal.
		One disadvantage of IM is that it is harder to determine whether the errors it portrays are symmetrical or not.
