The Tektronix Type S-311 Programmable Dual-Trace Sampling Plug-In Unit is a 560-series plug-in designed for use with the Tektronix S2000 and S3000­ Series Systems. In contrast to the 3S6 which uses external sampling heads, the S-311 contains two samplers internally, like the 3S76 or 3S1. However, unlike the 3S76 and 3S1, the S-311 gets its signal inputs via BNC connectors on the rear panel. The input impedance of each input is 50 ohms. The the S-311 is inserted into the mainframe, the BNC input connectors of the S-311 must be manually connected. The input connectors are not designed to pair with a corresponding connector in the plug-in bay bulkhead. The 567 mainframe has holes in the plug-in bay bulkhead at the location of the signal input connectors and programming connector of the S-311.

The S-311 can be though of as an 3S76 with remote programmability, connectors on the rear, no delay, and no trigger pickoff. The S-311 and 3S76 both have 0.4 nanosecond risetimes.

The S-311 does not contain a signal delay. The BNC signal input connectors on the rear panel of the S-311 are connected by short coaxial cables to the sampling bridge.
