Preface
This document helps customers with data security concerns to sanitize or remove memory devices from the FCA3000,
FCA3100, and MCA3000 Series instruments.
These products have data storage (memory) devices and data export devices (USB port and GPIB connector). These
instructions describe how to clear or sanitize the memory devices and disable the data output devices. The instructions also
describe how to declassify an instrument that is not functioning.

Preface
Terms
This document may use the following terms:
Clear.
This eradicates 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. A device that stores or exports data from the instrument, such as a USB
fl
ash
drive or USB port.
Sanitize.
This removes the data from media/memory so that the data cannot be recovered using any known technology.
This is typically used when the device is moved (temporarily or permanently) from a secured area to a nonsecured area.
Scrub.
This is equivalent to sanitize.
User-Accessible.
The user can directly retrieve the memory device contents.
User-Modi
fi
able.
The memory device can be written to by the user during normal instrument operation, using the
instrument user interface or remote control.
Volatile memory.
Data is lost when the instrument is powered off.
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 clearing
data, putting the instrument in Standby mode does not qualify as powering off. For these products, you must either
push a rear-panel OFF switch or remove the power source from the instrument.
Instrument Declassi
fi
cation.
A term that refers to procedures that must be undertaken before an instrument can be
removed from a secure environment. Declassi
fi
cation procedures include memory sanitization and memory removal,
and sometimes both.

Clear and Sanitize Procedures
Memory Devices
The following tables list the volatile and nonvolatile memory devices in the instrument.
Terminology
The tables in this section use the following terms:
User data – Describes the type of information stored in the device. Refers to waveforms or other measurement
information 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 information stored in the device. It means that 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 or user settings
are stored in the device.
Directly – Describes how data is modi
fi
ed. It means that the user can modify the data.
Indirectly – Describes how data is modi
fi
ed. It means that the instrument system resources modi
fi
es the data and that
the user cannot modify the data.

The Total Reset function writes 0xFF to all
fl
ash sectors that hold stored user data (saved measurement data).
The Total Reset function also resets
fl
ash sectors that hold current instrument settings (including power-on settings, but excluding instrument con
fi
guration settings) to their default (factory reset) settings. However, due to
internal sector organization of the
fl
ash memory, and depending on the size of the setting data, settings may be stored in two
fl
ash sectors. Parts of previous setting data might exist in a
fl
ash sector with the current setting
data. The Total Reset function sets the current settings storage memory to the default settings, but previous con
fi
guration settings data can persist in the noncurrent-settings locations within memory sectors.
