μATX and Power
Interface Removal (DPO7000 Series)
Removal of th
e μATX motherboard and the Power Interface assembly is a
complex process. To access or replac e either one, remove both the μATX
motherboard and the Power Interface board as an assembly. This procedure
assumes the Acquisition board has b een removed.
1. Working from the top of the instrument, unplug the cables connecting the
μATX and Power interface boards to other parts of the instrument. Note
where each cable connects.
2. Remove the screw securing the μATX board to the chassis on the right side of
the instrument, near the TekLink connector.
3. Remove the eight screws securing the μATX board to the chassis through
the back of the instrument.
4. Remove the three screws securing the μATX board to the chassis on the left
side of the instrument.
5. Position the instrument on its back, with the bottom facing you.
6. Remove the three screws securing the Power Interface assembly to the
chassis, along the top edge of the assembly.
7. Pull the μATX/Power Interface assembly out of the instrument.
(See Figure 4-3.) It may take some force to pull it free. Use a soldering aid to
pry the assembly free of the connectors near the top corners of the assembly,
if nec essary.
