7M11 is a plugin which contain two independent 50 Ohms analog delay lines with 75nS each. Risetime is specified as max. 175pS and attenuation is fixed at two. A separate trigger output is available to eliminate an external power splitter and it is attenuated by a factor of five. Unfortunately there are four GR-874 50-ohm connector and adapters are hard to find in the mean time.
Max. signal allowed is +-5V.
Because its completey passive and has no bus connector, it can be operated outside of the mainframe on the desk, giving free an additional slot for another plugin.
