Tektronix S54 The S54 Pulse Generator Head is a s

The S54 Pulse Generator Head is a step generator designed for use with the 7S12 as a long line Time Domain Reflectometer unit. Intended for tdr applications, the unit is 50 ohms reverse terminated to minimize reflections and has a 0 V base line to eliminate base line shift with load charges. A continuously variable front-panel control enables adjustment of pretrigger lead time. The pretrigger output allows the unit to be operated in sequential sampling systems without a delay line.
