Differential (100 Ohm) TDR Rise Time and Bandwidth Performace Testing
To measure the differential TDR performance, a 50 GHz TDR Sampling system was used to drive a Pico Second Pulse Lab 4022TDRT 9ps differential pulser which yielded a 17ps TDR system rise time when connected to the TDR Gigaprobes(tm).The measured rise time on the output of the TDR Gigaprobes(tm) was better than 30GHz as determined by the 10-90%.This probe is ideal for verifying a 10Gbit Backplane.
