The '''Tektronix 11000 Series plug-in interface''' is mechanically almost identical to the 7000 Series plug-in interface. | ==Interface Properties== | ||
The only mechanical difference is | ===Mechanical=== | ||
The 11000 Series has | The '''Tektronix 11000 Series plug-in interface''' is mechanically almost identical to the [[7000 Series plug-in interface]]. | ||
The only mechanical difference is at the top of the connector. | |||
The 11000 Series has a protruding narrow horn where | |||
the 7000 Series plug-ins have a wider horn at the top of the connector | |||
with four holes for extra electrical contacts (only known use is the [[7A21N|7A21N direct deflection plate access plug-in]]). | |||
The Tektronix 11000 Series plug-in interface is electrically partially the same as the 7000 Series interface. | ===Electrical Similarity to 7000-Series Plug-in Interface=== | ||
The power pins are the same, and the signal out pins are the same | The Tektronix 11000 Series plug-in interface is [[Similarity of 11000-series interface and 7000-series interface | electrically partially the same as the 7000 Series interface]]. | ||
7000-series plug-ins provide a single trigger feed to the mainframe on pins A13/B13 (differential). | The display and trigger signals have and impedance of 50 Ω. | ||
11000-series plug-ins | The power pins are the same, and the signal out pins are the same. | ||
and | 7000-series vertical plug-ins provide a single trigger feed to the mainframe on pins A13/B13 (differential). | ||
11000-series vertical plug-ins provide a trigger feed on pins A13/B13, | |||
and additionally provide trigger signals on B37/B38 and B35/B36. | |||
Note that despite this similarity, there are plenty of other issues − [[John Addis]] warns that converting 7k plug-ins to work in the 11k series or vice versa ''[[Similarity of 11000-series interface and 7000-series interface | "is not even close to being worth the effort"]]. | |||
===The RIGHT Slot on 11300 Scopes=== | |||
In the 11300, the right plug-in slot is special. It is, in some sense, a horizontal plug-in slot. | |||
A small caveat regarding 11300 nomenclature: | |||
In most places, the slots are referred to as "LEFT", "CENTER", and "RIGHT". | |||
However, in some internal documents, the slots are referred to as "LEFT", "RIGHT", and "AUX". | |||
One example of this potential confusion can be seen in the | |||
[[Media:Tek 11301 SDI signal wiring.png|11301 SDI signal wiring schematic]], | |||
where names of the wires on the left side of the schematic | |||
(i.e., pin names on the SDI chip) don't agree with the names of the wires | |||
on the right side of the schematic (i.e., the interface board pin names). | |||
This could cause confusion since "RIGHT" sometimes refers to the middle slot and sometimes | |||
refers to the rightmost slot. But the public documentation (and user interface) are consistent: | |||
the slots are called "LEFT", "CENTER", and "RIGHT". | |||
The RIGHT plug-in slot in 11300 scopes is funtionally a horizontal slot in the following ways: | |||
* The main signal output (pins 11A/11B) from the plug-in in the right plug-in slot cannot be routed to the vertical deflection plates of the CRT. | |||
* The main signal output (pins 11A/11B) from the plug-in in the right plug-in slot can be routed to the horizontal deflection plates. | |||
* The trigger output signals from the LEFT and CENTER plug-ins are routed to the RIGHT plug-in. This can be seen in the 11301 Interface Board schematic, an excerpt of which is here: [[Media:11301 right slot trigger inputs.png|Trigger signal feeds from LEFT and CENTER 11301 plug-ins to RIGHT plug-in]]. | |||
So in some sense, the right plug-in slot of 11300 mainframes is a horizontal slot. | |||
But Tektronix did not sell any general-purpose timebase plug-ins for the 11000 Series, | |||
so the only known application for this slot is the [[11T5H]] video trigger. | |||
As a matter of trivia, if one were to call the 11300's RIGHT slot a "horizontal" slot, | |||
then the 11300-series scopes might be the only Tek scopes that offer a timebase | |||
as a built-in part of the mainframe and also an easily swappable module (i.e., a plug-in). | |||
===The RIGHT Slot on 11400 and DSA600 Scopes=== | |||
In 11400 and DSA600 scopes, the trigger output from the LEFT and CENTER plug-ins | |||
are routed to the RIGHT plug-in's auxiliary trigger inputs. | |||
They are the same as the 11300 scopes in this regard. | |||
However, 11400 and DSA600 scopes have a three-input channel switch, in contrast to the 11300's two-input channel switch. | |||
Therefore, 11400 and DSA600 scopes can use the signal output from any of the three plug-in compartments | |||
as input to the digitizer, and as the vertical signal. | |||
===Digital Communication Between the 11000-Series Plug-in and the 11000-Series Mainframe=== | |||

11000-series | ===Calibration Voltage=== | ||
11000-series scopes introduced a much more extensive self-checking and self-calibration than the 7000 Series. | |||
Part of the self-calibration routine involves the | |||
11000-series mainframe sending a calibration voltage to plug-in via pins B35/B36. | |||
Those pins were not used in the 7000-series interface. | |||
===11k Detector=== | |||
The 11000-series interface uses pin B20 as an "11k Detector". | The 11000-series interface uses pin B20 as an "11k Detector". | ||
