The '''Tektronix 3S76''' is a dual-trace [[sampling oscilloscope|sampling]] plug-in for [[560-series scopes]].  
The inputs have 50 Ω impedance and use [[GR-874 connector]]s. Rise time is rated at less than 0.4 ns.

The initial design work on the 3S76 was done by [[Cliff Moulton]].
It was called the Type 76, later renamed 3S76 before going into production.
A decision was made to demonstrate the 76/3S76 at the 1961 IRE show.
This created a panic because the plug-in was not complete.
The 76 project landed in the TV group.
[[Ron Olson]] and [[Charlie Rhodes]] were designing it and [[Walt Lowy]] was a technician.
[[Phil Crosby]] worked in it for a week during spring break from Portland State (college then, not university). Phil Crosby designed the channel switching circuitry.
