[https://vintagetek.org/my-early-tektronix-days-by-john-kobbe-2/ John Kobbe says]: | |||
<blockquote> | |||
Later on there was another special CRT designed with [[distributed deflection plates|distributed vertical deflection]] for the 100 Megahertz 580 (well almost 100 MHz). The 580 was the first to, at least at Tek, to use a cross wound continuous signal [[[delay line]]. The 580 used a similar horizontal system lifted from the 530’s which was too slow and insufficient writing rate. The [[P80|active probe]] and [[580 Series plug-in interface|plug in system]] left a lot to be desired. I wasn’t very proud of the 580 design as it was too compromised. | |||
