Replacement
1. Reverse the order of the removal procedure.
NOTE When replacing the A59 source interface board, push the board evenly on all
the microcircuit pins.
Check all the pin sockets from the back of the A59 board to ensure that all of
the pins are inserted. For the 8722ET/ES models, you may need an eye glass
to inspect the shallow pins of the S1 high band switch.
When replacing the source module into the analyzer, push the cables aside
before seating the module.
