Preface
If you have data security concerns, this document helps you to sanitize or remove memory devices from the listed products.
These products have data storage (memory) devices and data output devices (USB ports). These instructions tell you how
to clear or sanitize the memory devices, and also tell you how to declassify an instrument that is not functioning.
Instrument code and calibration settings reside in nonvolatile flash memory. Instrument setups and reference waveforms
mayalsobestoredinflash memory or on USB drives connected to the instrument.
If you have any questions, contact the Tektronix Technical Support Center at www.tektronix.com/support.

Troubleshooting
How to Clear or Sanitize a Nonfunctional Instrument
If your instrument is not functioning and you need to clear or sanitize it, proceed as follows:
Acquisition Board
Compact Flash Card (TPS
oscilloscopes only)
USB Flash Drive (TDS
oscilloscopes only)
Charges
Remove the Acquisition board and return the product to Tektronix. A new Acquisition board will be installed, and the
instrument will be repaired and adjusted as necessary.
For removal instructions, refer to your product service manual. (See page iv, Related Documents.)
After removal of the Acquisition board, refer to your company's internal policies regarding handling or disposal of the
board.
Remove the compact flash card and return the instrument to Tektronix for repair.
After removal of the compact flash card, refer to your company's internal policies regarding handling or disposal of the
compact flash card.
Remove the USB flash drive and return the instrument to Tektronix for repair.
After removal of the USB flash drive, refer to your company's internal policies regarding handling or disposal of the
flash drive.
Replacement of any missing hardware will be charged according to the rate at the time of replacement.
