==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.
</blockquote>
==Internals==
=== Plug-in Interface ===
The 585 uses [[580-series plug-ins]] which look like [[letter-series and 1-series plug-ins]]
but are electrically different. The main difference is the impedance of the signal that passes
through the interface from the plug-in to the mainframe.
In 530/540/550-series scopes, the plug-in expects the mainframe to be a high impedance load,
driving tube grids in the mainframe.
The [[580 Series plug-in interface]], on the other hand, presents a differential transmission line
input with an impedance of 93 Ω per side, going into the first distributed amplifier stage.  The
other end of this transmission line is returned to the plug-in for termination and biasing.
The [[580 Series plug-in interface|pin-out of the interface connector]] is also different,
the 580-series pin-out being essentially flipped 180° from its 530/540/550 series counterparts
(''Signal Out'' is between pins 14 and 16 as opposed to between pins 1 and 3, etc.)
The [[81|Type 81]] adapter allows the use of letter-series and 1-series plug-ins in a 585.
=== Trigger Circuit ===
The original 585 (up to serial number 1070) has an "A" trigger circuit that has a differential
trigger amplifier made of a pair of [[6EW6]] miniature pentodes, followed by a Schmitt trigger
made of a pair of miniature dual triode tubes. 
Starting at serial number 1071 (and sometimes retrofitted to earlier instruments), the dual-triode
Schmitt trigger circuit was replaced by an [[STD615]] 10 mA [[tunnel diodes|tunnel diode]] AC-coupled to the base-emitter junction of an [[OC171]] germanium PNP transistor as a pulse amplifier. 
The slower "B" timebase uses a Schmitt trigger circuit.
=== Vertical Signal Path ===
Like the [[545]], [[551]], and [[555]], the 585 uses two [[distributed amplifier]]s in the vertical signal path, one with seven differential [[6DJ8]] stages driving a helically-wound, differential [[delay line]], followed by a five-stage differential distributed driver amplifier and a [[7699]] or [[6939]] dual tetrode power stage driving the CRT.
Unlike the other 500-series scopes, the 585 uses a CRT with [[distributed vertical deflection plates]], the [[T581]], enabling it to have both fast rise time and high sensitivity (~5 V/cm vertically), albeit at the cost of limiting vertical deflection to slightly over 4 cm. Total acceleration voltage is 10 kV.
Several improvements were published for the 585 circuitry, including the enhanced trigger circuit.
If all of those changes are applied to a 585, it is essentially a 585A.
After serial number 2585, the back termination of the final distributed amplifier output was made adjustable.
The manual says this (field-installable) modification (040-275) is "required for proper operation of plug-ins with numbers above [[81|Type 81]]". Non-A instruments with this termination have a front panel label reading "standardized vertical".
===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 regulator is used to supply the HV oscillator, a [[6AU5]].
A transistor-based regulator supplies a +12.6 V heater voltage to the plug-in.
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.
The 585 contains a 53°C (128°F) [[thermal cutoff]].
The power transformer, T601, is Tektronix part number [[120-0141-00]].
===Semiconductors===
The 585 uses semiconductor diodes as rectifiers and germanium transistors in the 12.6 V power supply, and except for unmodified instruments before SN 1070, a tunnel diode and another germanium transistor in the time base A trigger circuit.
=== Rackmount Versions ===
Rackmount versions were also made, the RM585 and RM585A.
