Isolation Adapter 01650-63203
Isolation adapters that connect to
the end of the probe cable are
designed to perform two functions.
The first is to reduce the number of
pins required for the header on the
target board from 40 pins to 20
pins. This process reduces the
board area dedicated to the prob-
ing connection. The second func-
tion is to provide the proper RC
isolation networks in a very con-
venient package.
