Removal and replace procedures
This section contains procedures for removal and installation of replaceable modules in the instrument. Refer to Replaceable
parts on page
35 for lists and exploded views of replaceable modules.
Any module inside of the chassis that does not have a remove and replace procedure requires that the entire instrument be returned to
Tektronix Service Center for service.
Warning: Before performing this or any other procedure in this manual, read the safety summaries found at the beginning of
this manual. Also, to prevent possible injury to service personnel or damage to the instrument components, read Preventing
ESD on page 15.
Before performing any procedure in this subsection, disconnect the power cord from the line voltage source. Failure to do so could
cause serious injury or death.
Before removing the rear chassis, order the 8 pieces of pre-cut aluminum tape (T
ektronix part number 253-0582-XX). The existing
tape has to be removed from the chassis to access the interior and cannot be re-applied after removal. The aluminum tape is only
needed for instruments with a serial number below B020000 or below C040000.
Note: Read the cleaning procedure before disassembling the instrument for cleaning.
