Deskewing Differential Cables
The next thing that must be done before you can measure differential
impedance is to deskew the TDR step generators to the end of the cables. The
following steps describe the deskewing process.
1 Connect an SMA cable to the TDR plug-in channel 1.
2 Connect an SMA cable to the TDR plug-in channel 2.
