TekSecure. If you have acquired confidential data on your oscilloscope, you may
want to execute the TekSecure function before you return the oscilloscope to
general use. The TekSecure function does the following tasks:
Replaces all waveforms in all reference memories with null sample values
Replaces the current front-panel setup and all stored setups with the factory
setup
Calculates the checksums of all waveform memory and setup memory
locations to verify successful compl etion of wavef orm and setup erasure
Displays a confirmation or warning message if the checksum calcula tion
is successful or unsuccessful
After you execute the TekSecure function, you must turn off the oscilloscope
power and then turn the power back on to complete the process.
