Preface
This document helps customers with data security concerns to sanitize or remove
memory devices from the DPO7OE Series Optical Probes.
These products have data storage (memory) devices. These inst ructions tell
how to clear or sanitize the memory devices. The instructions also tell how to
declassify
an instrument that is not functioning.

undertaken before an instrument can be removed from a secure environment.
Declassification procedures include memory sanitization and memory
removal, and sometimes both.
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.
Power off. Some instruments have a “Standby” mode, in which power is
still supplied to the instrument. For the purpose of clearing data, putting the
instrument in Standby mode does not qualify as powering off. For these
products, you will need to either pressarear-panelOFFswitchorremovethe

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.

The following terms are used in the tables in this section:
User data – Describes the type of information stored in the device. Refers to
waveforms or other measurement data representing signals connected to the
instrument by users.
User settings – Describes the type of information stored in the device. Refers
to instrument settings that can be changed by the user.
Both – Describes the type of informationstoredinthedevice. Itmeansthat
both user data and user settings are stored in the device.
None – Describes the type of information stored in the device. It means that
neither user data nor user settings are stored in the device.
Directly – Describes how data is modified. It means that the u ser can modify
the data.
Indirectly – Describes how data is modified. It means that the instrument
system resources modify the data and that the user cannot modify the data.

Troubleshooting
How to clear or sanitize a nonfunctional instrument
If your instrument is not functioning, perform the following actions and return the
instrument for Tektronix for repair. Describe the initial problem with the product.
Tektronix will install repla cement parts and then repair and return the instrument.

User calibrated wavelength conversion gains are stored in the probe

How to recover from clearing or removing the instrument’s memory
Using the Erase User Wavelengths button in TekScope does not require any
al recovery procedure. (See page 2, Clear flash procedure.) The probe can

continue to be used, and new user calibrated wavelength conversion gains can
be stored. If U204 is removed from the OE Power and Control board, the entire
probe must be returned to Tektronix for repair and calibration.
