Clear and sanitize procedures
Memory devices
The following tables list the volatile and nonvolatile memory devices in the
instrument. Detailed procedures to clear or sanitize these devices, if any, are
shown following each table.
Terminology
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 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 nor 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 modify the data and that the user cannot modify the data.
