TDR reflectometer T3SP series

time-domain

Teledyne Test Tools T3SP15D stimulates the DUT with true differential signals. The T3SP15D offers fast rise times of 35 ps for spatial impedance resolution (in FR4) of 3 mm, at DUT lengths up to 40 meters and TDR repetition rates up to 10 MHz and uses the same open short load thru (OSLT) calibration standards as vector network analyzers. With their small form factors, light weight, and optional internal batteries, the instruments go anywhere in test labs or in the field at an affordable price. Key Features •True Differential TDR with <3mm Spatial Resolution •Small Form Factor and Battery Powered •S Parameters up to 15 GHz •35 ps Rise Time •Up to 50,000 points long memory •Emerging Serial Data Standards Testing True-Differential Time Domain Reflectometers (TDRs) Most of the modern high-speed designs are implemented with differential transmission lines. Using a true differential TDR simplifies the setup for signal integrity measurements in such designs. In some scenarios the ground connection could be difficult to connect or not accessible if you want measure unshielded twisted pair cables. Most of the time, when you take measurements using a true differential TDR a ground connection is not required and gives you the flexibility to use TDR-probes without a ground connection. Fast TDR Repetition Rate With up to 10 MHz repetition rate the T3SP-series is more than 300 times faster as conventional TDR instruments which are based on sampling scopes. To achieve the highest possible dynamic range TDR instruments need to acquire and average out hundreds of waveforms. The faster sampling rate delivers quicker and more accurate measurement results.
