To remove and replace the acquisition board assembly
Use this procedure to remove and replace the acquisition assembly. When necessary, refer to
other removal procedures. The graphics in this chapter are representative of the oscilloscope at
the time of this printing. Your unit may look different.
1
Disconnect the power cable and remove the bottom cover.
2 Remove the AutoProbe assembly (see page 104).
3 Remove the hex nuts that secure the BNC connectors to the front panel.
Use a 9/16” nut-driver to remove the hex nuts. See page 108.
4
Disconnect the three or four SMB cables from J13, J14, J15, and J16 from the acquisition
board assembly.
5 Disconnect the following cables from the inside edge of the Acquisition assembly:
• Power supply sense cable
• Probe control cable
• Power harness cable
• Line sync cable
•Acquisition cable
• Internal digital cable (MSO model oscilloscopes only)
These cables are attached to J5, J150, J6, J7, J9, J10, and J18 connectors. The J18 connector is
near the CH4 attenuator.
6
Remove the 13 Torx T10 screws that secure the acquisition board to the chassis, then
lift the board back from the front panel until the BNC connectors clear the panel. Lift
the board away from the chassis.

7 To re-install the acquisition board assembly, reverse the above procedure. Be sure to
observe correct polarity for all cables and torque the BNC hex nuts to 2 Nm (18 in-lb).
