5S14N
The Tektronix 5S14N is a 1 GHz dual-trace delayed sweep sampler plug-in. It is almost identical to the 7S14 plugin (from the 7000 series) except for the omission of read-out circuits.
It is a complete sampling system unlike, for example, the 7S11, which requires a separate sampling timebase plug-in to provide triggering and sampling pulse generation.

Internals
The 5S14N contains two samplers, trigger and sweep circuitry, and circuitry to interface it with the 5000-series mainframe in which it operates. The mainframe provides the 5S14N with power. As a combined horizontal/vertical plug-in the 5S14N sends the mainframe both horizontal and vertical signals.
There are two 1.35 V mercury button cells, BT1 and BT2, in the sampler circuit. They act as floating bias sources, so if a 5S14N stops working it may be not defective apart from the dead batteries.
The sampler used by the 5S14N is a two-diode design. Each of the two input channels has its own sampler.
Most boards in the 7S14 and 5S14N are common. However, since 5000-series plug-ins are shorter than 7000 series and the mainframe interface is different, the 7S14 contains two 7000-specific interface boards (horizontal/vertical) that plug into the 7000 series mainframe. The common main horizontal board has the 5000-series interface connector fingers at the rear, which remain hidden within the 7S14 (see photo).
