Measuring Transmission Line Percent Reflection
This section shows how to measure transmission line percent reflection with a
step risetime of 500 ps. To perform the tasks in this section, you need the
following:
• 1 good quality SMA cable one meter in length, such as the HP 8120-4948
cable.
• 1 each demo board (54754-66503) supplied with the TDR plug-in.
•1 SMA short.
• 1 SMA 50 ohm load.
• 1 HP 54754A or HP 54753A TDR Module.
The following procedure shows how to perform a percent reflection
measurement.
1
Connect a 1 m SMA cable to channel 1 of the TDR plug-in module.
2
Connect the other end of the cable to the demo board’s single
transmission line connector that is closest to the wide trace
(Figure 7-15).
