TDS6000, TDS6000B, TDS7000, TDS7000B,
CSA7000, and CSA7000B Technical Report
Date: May 6, 2004
Amended: September 17, 2010 Added TDS6000C
Subject: Memory Erasure on TDS6000, TDS6000B, TDS6000C, TDS7000, TDS7000B,
CSA7000 and CSA7000B oscilloscopes
These products contain an open architecture PC with REMOVABLE hard drive. All user
storable data is stored on the removable hard drive. Setups are stored in NV RAM.
Located in the Utilities menu, Tek Secure™ capability is available for TDS6000,
TDS6000B, TDS6000C, CSA7000, CSA7000B, TDS7000, and TDS7000B
oscilloscopes. Tek Secure erases and overwrites all the waveform and setup memories.
The waveform memories, stored on the hard drive, are overwritten with an “empty,” all
zeros pattern. The setup memories, stored in NV RAM, are overwritten with the factory
default front panel setup. The current front panel setup is also overwritten with the
default factory setup.
The hard drive is removable on all TDS6000, TDS6000B, TDS6000C, CSA7000,
CSA7000B, TDS7000, and TDS7000B models. It is located on the real panel, standard,
or on the front panel as an option. Remove the hard drive to be stored or destroyed.
Additional hard drives can be purchased from Tektronix.
Floppy disk drives are standard on most TDS6000, TDS6000B, CSA7000, CSA7000B,
TDS7000, and TDS7000B models. Remove all floppy disks. These can be stored or
destroyed.
Most TDS6000, TDS6000B, TDS6000C, CSA7000, CSA7000B, TDS7000, and
TDS7000B models include read/write capable CD ROM drives. Remove all CDs. These
can be stored or destroyed.
Using Tek Secure will not affect calibration of the instrument because the calibration
constants are stored on the acquisition board completely separate from any acquisition
data. This allows complete erasure/removal of any secure data without affecting scope
calibration. It also allows the oscilloscope to be calibrated in a non-secure site then used
in a secure area without need for recalibration. Following removal or exchange of the
hard drive, it will be necessary to run the SPC procedure in the Utilities menu after a 20minute warm-up period.
The following instructions give a method to disable the built-in USB and CD-RW
capability of these scopes. Using the BIOS disables the devices for DOS programs, while
the Windows Device Manager disables the devices for Windows programs. These
procedures assume the intent is to disable both USB and CD-RW to stop any attempt to
use them.
To disable USB and CD-RW for DOS via the BIOS:
1. Press F2 during instrument Boot Up to go to the BIOS configuration menu.
2. Go to Advanced->USB Configuration, set High-Speed USB and Legacy USB Support to
Disabled.
3. Go to Advanced->IDE Configuration, set IDE Controller to Primary. CD-RW is in the
secondary IDS bus, thus, disabled.
4. Go to Security-> Set Supervisor Password, press return to set a Supervisor password, then go
to User Access Level and set it to No Access.
5. Exit Saving Changes.
To disable USB and CD-RW for Windows via the Windows Device Manager:
1. Plug in a PS2 mouse and a PS2 keyboard because USB will be disabled.
2. In Windows Control Panel, click System, click Hardware tab, click Device Manger... button
and launch the Device Manager window.
3. Expand Universal Serial Bus Controller; identify the three USB Root Hub listings
(TDS6000C has four USB Root Hub listings). Right click the first listing and the third &
fourth listing and select Disable. Do not disable the second USB Root Hub because the Touch screen and USB floppy disk use it.
4. Expand DVD/CD-ROM drives in the Device Manager window, identify TEAC CD-
RW224EA, right click it and select Disable.
5. Reboot the scope to make the changes effective.
