Tektronix SD-24 070-7053-00 TDR Sampling Head Service Reference Manual 1988

Tektronix SD-24 070-7053-00 TDR Sampling Head Service Reference Manual 1988

This is the original Tektronix Service Reference Manual for the SD-24 TDR (Time Domain Reflectometry) Sampling Head, publication number 070-7053-00. First printed in August 1988 and revised June 1989, this manual covers the full service, calibration, and theory of operation for the SD-24 sampling head as used with the Tektronix 11000 Series Measurement System. Notably, this copy includes the original Tekware SD-Series Sampling Head Utility Software on a 5.25-inch floppy disk (part number 062-0897-00, Version 1.0), which is stored in a plastic sleeve pocket inside the front cover.

Applications

The Tektronix SD-24 is a TDR (Time Domain Reflectometry) sampling head designed for use with the Tektronix 11000 Series mainframe measurement systems, a high-performance sampling oscilloscope platform from the late 1980s. TDR sampling heads are used to characterize the impedance and reflection properties of transmission lines, cables, connectors, and circuit board traces — essential work in high-speed digital design, RF/microwave engineering, and signal integrity testing. The 11000 Series with plug-in sampling heads like the SD-24 was a standard tool in telecommunications labs, semiconductor test environments, and precision electronics research facilities of its era. Service manuals like this one are essential for calibration, repair, and maintenance of SD-24 units still in service, and are sought by metrology labs, instrument repair technicians, and vintage Tektronix collectors. The included Tekware utility software floppy adds additional value for facilities that still operate the original hardware.
