Clear. This removes data on media/memory before reusing it in a secured
area. All reusable memory is cleared to deny access to previously stored
information by standard means of access.
Erase. This is equivalent to clear.
Media storage/data export device. Any of several devices that can be used
to store or export data from the instrument, such as a USB port.
Nonvolatile memory. Data is retained when the instrument is powered off.
Remove. Thisisaphysicalmeanstoclearthedatabyremovingthememory
device from the instrument. Instructions are available in the product Service
Manual.
Sanitize. This eradicates the data from media/memory so that the data cannot
be recovered by other means or technology. This is typically used when the
device will be moved (temporarily or permanently) from a secured area to a
non-secured area.
Scrub. This is equivalent to sanitize.
User-modifiable. The user can write to the memory device during normal
instrument operation, using the instrument interface or remote control.
Volatile memory. Data is lost when the instrument is powered off.

Clear and Sanitize Procedures
Nonvolatile Memory
Security Procedure
User data is not stored in nonvolatile memory. To secure nonvolatile memory,
proceed as follows:
1. To remove the LPU board from the module, refer to the appropriate module
service manual for the remove and replace procedures. (See page iv, Related
Documents.)
2. To remove the Enhanced Monitor board from the TL7XM mainframe, refer to
the TLA721 Benchtop & TLA7XM Expansion Mainframe Service Manual for
the remove and replace procedures. (See page iv, Related Documents.)
3. To remove the TLA7PG2 Clock & Backplane interface board or the
TLA7PG2 PG board, refer to the TLA7PG2 Pattern Generator and Probes
Service Manual for the remove and replace procedures. (See page iv, Related
Documents.)
4. Since there is no way for you to clear nonvolatile memory, either store these
circuit boards in a secure area or destroy them.

Troubleshooting
How to Sanitize or Clear a Nonfunctional Instrument
If your instrument is not functioning and you need to clear it, remove the power
source from the instrument for at least 20 seconds.
To sanitize the instrument, remove the circuit boards and either securely store
them in a safe location or destroy them. You can also return the circuit boards to
Tektronix; Tektronix will repair and replace the circuit boards as necessary.
