Direct connection

For all Agilent logic analyzers except 16517A, 16518A, 16760A, and 16753/54/55/56A.

You can connect the logic analyzer cable directly to a 40-pin connector, but you must install the proper isolation network directly onto the target system board.

If drawing current from the 5V supply, do not exceed 0.33 amps per cable. The cable ground lines are chassis (earth) grounds and not "floating" grounds. All the lines are woven into a flat ribbon that is 137.16 cm (4.5 feet) long.

Agilent Technologies recommends two types of RC networks. They are described in detail in Probing Solutions for Agilent Logic Analysis Systems.
