The Tektronix 7M11 is a plug-in which contains two independent 50 Ohm analog delay lines with 75 ns each. Risetime is specified as 175 ps maximum, and attenuation is fixed at two.
A separate trigger output is available to eliminate an external power splitter. Signal through the trigger pick-off output is attenuated by a factor of five. Delay line connections are 50-ohm GR-874, trigger pickoff is through a BNC connector.
The maximum signal allowed is +/- 5V. The mass of the 7M11 about 2.5 kg, so be careful when sliding it into the slot. (Generally, Tektronix specifies not to ship mainframes with inserted plug-ins, to protect the bus connectors!)
Because it is completely passive and has no bus contacts, the 7M11 can be operated outside of the mainframe on the desk, freeing a slot for another plug-in.
