Clear and sanitize procedures
Memory devices
The following tables list the volatile and nonvolatile memory devices in the standard instrument and listed options. Detailed procedures to
clear or sanitize these devices, if any, are given 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 modified. It means that the user 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.
