The '''Tektronix 7M11''' is a plug-in which contains two independent 50 Ω, 75 ns analog delay lines with [[GR-874 connector]]s. Rise time is specified as 175 ps maximum, and attenuation is fixed at 2:1.

The '''Tektronix 7M11''' is a plug-in which contains two independent 50 Ω, 75 ns analog delay lines. Rise time is specified as 175 ps maximum, and attenuation is fixed at 2:1.

~~Delay line connections are 50 Ω [[GR-874]]~~.

To eliminate an external power splitter, a separate trigger output is available through a [[BNC connector]] at 5:1 attenuation (line 1 or 2 switch selectable).

~~The maximum signal allowed is ±5 V.~~

The mass of the 7M11 is about 2.5 kg (5.5 lb), so one must be careful when sliding it into the slot. (Generally, Tektronix specifies not to ship mainframes with inserted plug-ins, to protect the bus connectors!)

Tek originally made a carrying enclosure (437-0106-00) to hold a 7M11 for desk use.

The interface between the GR-874 input connector and the trigger pickoff board is described in [~~https://www.google.com/patents/US3426311~~ US Patent 3,426,311], and is similar to the ones in the [[S-1]] and [[S-2]] samplers.

The [[035-5031-00]] TM500 plug-in is roughly equivalent to one half of a 7M11.
