Preface

This document helps customers with data security concerns to sanitize or remove

memory devices from the WVR7200 Waveform Rasterizer.

These products have data storage (memory) devices. These instructions tell

how to clear or sanitize the memory devices. The instructions also tell how to

declassify an instrument that is not functioning.

Products This document covers all WVR7200 instruments.

Preface

Terms The following termsmaybeusedinthisdocument:

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.

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 press a rear-panel OFF switch or remove the

power source from the instrument.

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.
