Memory Erasure and Memory Parts List
The standard THS700, THS700A, and THS700P Series instruments contain a
proprietary architecture based on a Motorola 68k microprocessor and the
VxWorks operating system. Instrument code and calibration settings reside in
nonvolatile FLASH memory.
Instrument setups and reference waveforms are also stored internally in FLASH
memory.
If you have any questions, contact the Tektronix Technical Support Center at
http://www.tektronix.com/support
Memory Erasure
To erase confidential setup and reference waveform data from the FLASH
memory on your oscilloscope, use the Tek Secure function. The Tek Secure
function does the following:
H Replaces all waveforms (oscilloscope and data logger) in all reference
memories with zero 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. Tek Secure does not erase or change factory calibration constants.

Memory Erasure and Memory Parts List
To use the Tek Secure function to erase FLASH memory:
1. Push the front—panel UTILITY button.
2. Push the Tek Secure Erase Memory bottom bezel button.
3. Push the OK Erase Setup/Data bottom bezel button.
4. Push the OK Overwrite Setup/Data bottom bezel button, and wait for the
completion of TekSecure.
5. Power off the oscilloscope; then power on the oscilloscope to complete the
process.
