Applications
The Tektronix 11401 and 11402 were flagship high-performance digitizing oscilloscopes introduced in the late 1980s, offering 1 GHz and 2 GHz analog bandwidth respectively, built on Tektronix's modular 11000-series mainframe platform. They were used in demanding R&D, telecommunications, and precision measurement environments where high-speed signal acquisition and digitizing accuracy were critical. This Service Reference Manual is the primary resource for technicians performing depot-level or bench-level service on these instruments, covering everything from routine calibration adjustments to board-level troubleshooting and FRU replacement. It remains an essential reference for anyone maintaining, repairing, or restoring a Tektronix 11401 or 11402 today, whether in a university lab, a vintage instrument repair shop, or a facility still operating legacy test equipment from this era.
This Tektronix 11401/11402 Digitizing Oscilloscopes Service Reference Manual has been inspected and is in good used condition. The binding is intact, the pages are present and legible throughout, and the cover shows normal shelf wear typical of a spiral-bound technical manual of this age.
