Memory Devices - Tektronix MSO46B Declassification And Security Instructions

• 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 modifies the data and that the user cannot
modify the data.
