Direct connection

Direct connection
NOTE: 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.

CAUTION: If drawing cur rent from th e 5V supply, do not exc eed 0.33 amp s per cable. Th e

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.

NOTE: Agilent Technologies recommends two types of RC networks. They are

described in detail in Probing Solutions for Agilent Logic Analysis Systems.
