11000 Series plug-in interface

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 had a protruding narrow horn where the 7000 Series plug-ins have a wider horn at the top of the connector with electrical connections in some cases, e.g., in the 7A21.

The Tektronix 11000 Series plug-in interface is electrically partially the same as the 7000 Series interface. The power pins are the same, and the signal out pins are the same. There are no horizontal plug-in slots (timebase is internal to the instrument). 7000-series plug-ins provide a single trigger feed to the mainframe on pins A13/B13 (differential). 11000-series plug-ins also provide a trigger feed on pins A13/B13, and also provide trigger signals on B37/B38 and B35/B36.

11000-series plug-ins do not implement the 7000-series readout interface. The pins that are used for readout in the 7000-series are not used in the 11000 Series.

In the 11000 Series architecture, the mainframe communicates with the plug-in over a serial digital link called SDI. SDI uses pins A20, A21, and B21 on the plug-in connector. Those pins were not used on vertical plugins in the 7000-series interface (and the 11000-series does not support horizontal plugins).

11000-series mainframes send a calibration voltage to plug-in via pins B35/B36. Those pins were not used in the 7000-series interface.

The 11000-series interface uses pin B20 as an "11k Detector". 11000-series plug-ins have a pull-up resistor on pin B20. 7000-series (vertical) plug-ins left pin B20 unconnected.

Notes

[note 1] 7000 mainframes provide ±50 V supplies on A19/B19, 11000 series does not (plugins requiring 50 V don't work)
