4.2
Handling the coaxial cable when using a general purpose
connector
When using a general purpose connector instead of a coaxial cable-specific part for the user system
connector, create the coaxial cable and connector assembly by adhering to the following points as
shown in Figure 4-2.
■
All of La and Lb are included in the total wiring length limit on L2 from the previous section.
■
For the electrical characteristics, it is recommended that the coaxial cable is directly connected to
the target board using a general-purpose connector without using the second connector
(including parallel signal wires).
