Teledyne LeCroy T3SP series differential time-domain reflectometers

Teledyne LeCroy has released the T3SP series differential time-domain reflectometers. The Model T3SP10D (10 GHz) and Model T3SP15D (15 GHz) stimulate the DUT with true differential signals.

The TDRs offer fast rise times of 50 (T3SP10D) and 35 ps (T3SP15D) for fault resolution (in FR4) of 4.2 and 3 mm, respectively, at DUT lengths of up to 40 m and TDR repetition rates of up to 10 MHz using the same open short load (OSL) calibration standards as vector network analysers.

With up to 10 MHz repetition rate, the products are said to be more than 300 times faster than conventional TDR instruments. The series also offers fully calibrated differential S-Parameter measurements up to 15 GHz (T3SP15D), using the same OSLT-calibration standards used by VNAs.

The products can acquire up to 50,000 points, giving a long TDR record capture with high resolution on long DUTs. If the DUT being measured is long, the number of points that can be acquired is limited by the timing resolution of the TDR-plot. The user has the flexibility to change the TDR repetition rate from 10 to 1 MHz, offering good timing resolution for cable lengths up to 40 m.

Due to their small form factors, light weight and optional internal batteries, the time-domain reflectometers are suitable for use in test labs or in the field. Output files can be stored in a variety of formats (CSV, Matlab and Touchstone) that can be easily used in tools like SI-Studio, Matlab or other simulation programs.
