==History== | |||
[https://vintagetek.org/my-early-tektronix-days-by-john-kobbe-2/ John Kobbe said]: | |||
<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, at least at Tek, to use a cross wound continuous signal [[delay line]]. | |||
The 580 used a similar horizontal system lifted from the 530s which was too slow and [had] 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. | |||

After serial number 2585, the back termination of the final distributed amplifier output was made adjustable. | |||

===Power Supply=== | ===Power Supply=== | ||
The 585 power supply is similar to other Tek scopes of the era such as the [[549]]. A linear regulator with a [[5651]] reference tube, a [[12AX7]]/[[6AU6]] error amplifier and three parallel [[12B4]] series pass tubes produces −150 V. This is the only adjustable rail, all other regulated voltages are referenced to it. The +100 V and +350 V regulators use half a [[6080]] each as the pass element, the +225 V two. In the +500 V path, a [[12B4]] performs this function. The unregulated +325 V input to the 225 V | The 585 power supply is similar to other Tek scopes of the era such as the [[549]].

The +100 V and +350 V regulators use half a [[6080]] each as the pass element, the +225 V two. | |||
In the +500 V path, a [[12B4]] performs this function. | |||
The unregulated +325 V input to the 225 V regulator is used to supply the HV oscillator, a [[6AU5]]. | |||

A [[delay relay| | A [[delay relay|6NO45 delay relay]] controls a multi-contact relay to switch supply voltages on only after the tubes are warmed up. | ||
When the main relay engages, the delay relay is cut out so it will be ready to delay again even after a quick interrupt in power input. | |||
The 12.6 V power supply is referenced to the +100 V regulated output. Since +100 V is not available during the warm-up period, an unregulated +100 V (~+180 V) is fed as the reference to the 12.6 V power supply during the warm-up period, then cut out by the multi-contact relay post warmup. | |||
