Memory Erasure and Memory Parts List
The standard TDS3000 and TDS3000B Series instruments contain a proprietary
architecture based on a PowerPC and the VxWorks operating system. Instrument
code and calibration settings reside in FLASH memory.
Instrument setups and reference waveforms can be stored internally in FLASH or
on the internal floppy disk drive.
Instrument code can be updated by the user from floppy disks. The latest
firmware is available on www.tektronix.com. Loading firmware does not
overwrite instrument calibration settings. Loading new firmware does not
guarantee overwriting the instrument setups and reference waveforms. To
guarantee FLASH memory erasure, use the TekSecure function.
If you have any questions, contact the Tektronix Technical Support Center at
http://www.tektronix.com/support.
Memory Erasure
Floppy disk drives are standard on TDS3000 and TDS3000B models. Removed
floppy disks can be stored or destroyed.
To erase confidential data in the FLASH memory on your oscilloscopes, use the
TekSecure function. The TekSecure function does the following:
H Replaces all waveforms in all reference memories with null sample values
H Replaces the current front-panel setup and all stored setups with the default
factory setup values
H Calculates the checksums of all reference waveform memory and setup
memory locations to verify successful completion of waveform and setup
erasure
H Displays a dialog indicating whether the secure erase was successful or
unsuccessful
NOTE. TekSecure does not erase or change factory calibration constants or
Ethernet settings.

Memory Erasure and Memory Parts List
To use the TekSecure function to erase FLASH memory:
1. Push the front-panel UTIL ITY button.
2. Push the System bottom bezel button until Config is selected.
3. Push the TekSecure Erase Memory bottom bezel button.
4. Push the OK Erase Setup & Ref Memory side bezel button.
5. Power off the oscilloscope; then power on the oscilloscope to complete the
process.
Disable LAN Ethernet Connectivity
(TDS3000 Series with TDS3EM Module, and All TDS3000B Models)
To disable LAN Ethernet connectivity:
1. Push the front-panel UTIL ITY button.
2. Push the System bottom bezel button until I/O is selected.
3. Push the Ethernet Network Settings bottom bezel button.
4. Push the Change Instrument Settings side bezel button.
5. Clear all settings. If you need to restore network connectivity at a later date,
make sure to write down all setting values before clearing them.
6. Push the OK Accept side bezel button.
The LAN system is disabled and no longer allows data traffic in or out.
