Test Tools Pinpoint Signal-Integrity Issues

Teledyne LeCroy’s Teledyne Test Tools (T3) establishes a turnkey platform that features two reportedly ultra-portable, inexpensive, reliable, and highly accurate time-domain reflectometers (TDRs). The two TDRs, the T3SP10D (10 GHz) and T3SP15D (15 GHz), stimulate the device under test (DUT) with true differential and common-mode signals. This unique combination enables designers of high-speed data channels, test engineers, and field technicians to precisely locate impedance discontinuities that can adversely affect a data signal's rise times, pulse width, timing, jitter and noise content, resulting in degradation of overall system reliability and functionality. Using the same open short load (OSL) calibration standards as vector network analyzers, the TDRs reach high levels of impedance plot accuracy.

 

With a small form factor, light weight, and optional internal batteries, the instruments can go anywhere in test labs or in the field to measure impedance discontinuities in applications such as ECUs, Automotive Ethernet, and cable testing, and in industries including automotive, aerospace/defense, IC manufacturing, and telecom. They precisely identify and diagnose signal-integrity issues in interconnects, transmission lines, serial-data channels, and cables.

 

Other features include rise times of 50 ps (T3SP10D) and 35 ps (T3SP15D) for fault resolution (in FR4) of 4.2 mm and 3 mm, respectively, at DUT lengths of up to 40 meters, TDR repetition rates up to 10 MHz, and an ESD protection module based on high-performance coaxial RF switches that protect the TDRs' RF-signal detectors from the input connector when the instrument is not in use.

 

The Teledyne Test Tools T3SP10D and T3SP15D TDRs are available now at prices starting at $19,780. Options include internal battery, storage/travel case, phase-matched cables, differential probes, calibration kits, and on-site training.
