Logic Analyzer Technical Report
Date: Oct. 12, 2005
Subject: Memory Erasure & Parts in TLA7012.
MEMORY ERASURE PROCEDURE
This product contains an open architecture PC with a removable hard drive. All user storable data is stored on the
hard drive. There are DOD approved scrubbing software packages available for the hard drive. We have no
recommendations regarding the available packages. After the hard drive has been scrubbed, you can reinstall the
operating system using the Image CD that came with the Logic Analyzer. This returns the Logic Analyzer hard drive to
the initial factory shipped state.
Another approach is that you can simply remove the removable hard drive. It is located on the side panel for easy
removal. This drive can then be stored or destroyed.
Turn the power off for at least 20 seconds to clear volatile memory.
Remove setup information from the BIOS by resetting the BIOS to default on power-up. Before exiting the BIOS setup,
go to the Configuration page and select Video Configuration. Make the following changes:
• Set the Boot display setting to CRT+LFP
• Set the Local Flat Panel setting to Enabled.
• Go to the LFP Control Sub Menu and change the Backlight Control setting to PWM.
Save and Exit the BIOS setup.
Remove all CDs. Rewritable CDs can be formatted, stored or destroyed. Non-rewritable CDs can either be stored or
destroyed.
If you have any questions, contact the Tektronix Technical Support Center at 1-800-833-9200*3.
