Hello.
Does anyone know if RT Russell can supply the test card generator any more, mine seems to have bit the dust, I have come across another type but I like RT Russells one.
Cheers
Trevor

They're not very complex - just a large memory, an interface to program the memory and a counter to read out the contents. Then a DAC and output buffer. Not sure whether it's all in programmable logic. May well be fixable, espeically if somebody else has one to make comparisons.

Hi,
I wished to purchase a RT Russell test card generator about 12-18 months ago and RT Russell directed me to the above site. I did not receive any replies to my email requests to them so I hope you have better luck than I had. Please let us know how you go on.

Best Regards

Fred ( G0BYU )
