True-differential TDRs pinpoint signal-integrity measurement

TELEDYNE LECROY Test Tools (T3) branded portfolio of test equipment now includes two ultra-portable, inexpensive, reliable time-domain reflectometers (TDRs). Models T3SP10D (10GHz) and T3SP15D (15GHz) combine portability, reliability and functionality. Before the availability of Teledyne LeCroy’s 10- and 15-GHz TDRs, portable tools were either much costlier high-end TDRs, or single-ended instruments with limited functionality. Units stimulate the device under test (DUT) with true differential and common-mode signals. This combination enables users 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.
