About this task
Removing the M.2 memory board sanitizes the instrument, ensuring that user settings and acquisition data are no longer on the
instrument. Removing the M.2 board also removes the instrument calibration constants and any option licenses that you have installed.
Note: The M.2 memory board is only in instruments with a serial number below B020000 or below C040000.
Note: If the M.2 board is removed before sending the instrument to T
ektronix for repair, Tektronix will install a new M.2 board and
you will be charged for the new board.
You will need to reassemble the instrument and send it to your nearest Tektronix Service Center to have a new M.2 board installed and the
instrument recalibrated.
After the instrument is returned, you will need to reinstall any option licenses.
Procedure
1. Remove the seven
T-10 Torx screws from the carrier board (marked in red). Remove the five T-8 Torx screws from the carrier board
heat sink (marked in yellow).
