TDR and VNA measurements shed light on Gbits/s interconnects
News & Analysis  
4/26/2004   Post a comment
With Time Domain Reflectometry (TDR) designers can deduce information on device-under-test (DUT) properties as the location of failures, the line impedance and the time delays for high speed signals, writes Dima Smolyansky, measurement expert at TDA Systems. But Frequency Domain Vector Network Analysis (VNA) using a synchronized sweep between a sine wave stimulus, and a narrow band filter at the receiver end requires additional software to make sense of the picosecond-readings captured by TDR sc
