Tek Secure. If you have acquired confidential data on your oscillo-
scope, you may want to execute the Tek Secure function before you
return the oscilloscope to general use. The Tek Secure function does
the following tasks:
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 factory setup
H
Calculates the checksums of all waveform memory and setup
memory locations to verify successful completion of waveform
and setup erasure
H
Displays a confirmation or warning message if the checksum
calculation is successful or unsuccessful
After you execute the Tek Secure function, you must turn off the
oscilloscope power and then turn the power back on to complete the
process.
