Installing a Retention Module on the Target System Board
You must install an E5403A retention module on the target system board. The retention module
attaches the E5405A probe to the target system board and ensures soft touch pin-to-PC board pad
alignment. A kit of five retention modules are supplied with each E5405A probe. If you need more
retention modules than the number of modules included in the probe shipment, you can order the
part number
E5403A
that contains a set of 5 retention modules.

board. Align and then insert the retention module into the footprint.
2 Solder the pins on the retention module to the footprint on top of the target system board.
NOTE
You must connect the pins colored black in
to GND on the target
system.
