Isolation Adapters
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. This process reduces
the board area dedicated to the
probing connection. The second
function is to provide the proper
RC isolation networks in a very
convenient package.
