Two images stand out in representing Tektronix and its legacy. One is the "Tek Bug" which first used a round CRT and was later updated to a rectangular CRT as shown on this front panel logo.
The other image is the "Wizard" which was shown on the vertical amplifier schematic in the 454 manual because this fast circuitry was magical.
The Wizard was also listed in the parts list.
The museum assembled and sold out of 300 Demonstration Boards on our eBay store which draws these two patterns on an oscilloscope in XY mode (we no longer sell the assembled Demonstration Board but we do sell a kit of parts). Check our eBay store for details.
This was a small (1.2 x 2.5 inches) circuit board with a processor and R2R D-to-A converters that will generate patterns on an oscilloscope operating in XY mode. The two patterns display alternately for a few seconds each.
In fact, this demonstrator board looks great even on a competitor's scope as shown in this photo sent to the museum by a happy customer.
The board was updated and included the capability of playing Table Tennis!
Here are some enthusiastic kids playing tennis at the museum on a 465 oscilloscope.
Alan Wolke on his w2aew YouTube Channel uses the demonstrator board to compare differences in XY mode on analog and digital oscilloscopes.
We continue to get requests for this Demo Board so we have chosen sell a kit of parts. Construction is not difficult but does require some electronic skills. The kit contains only the programmed microprocessor and the schematic so you have to supply a prototype board, a power supply, and a few components. Check our eBay store for details. We also now have the Gerber files available for download if you want to make your own PCB. Otherwise it is simple to build on a prototype board.
Two customer sent us photos of their boards so you can see the complexity of the build. This one was built on a prototype board.
This one was built on an Arduino UNO board.
