When to use TekSecure
™
Use the TekSecure function to erase setup and reference waveform data stored in
internal flash memory. Using TekSecure will not affect the calibration of the
instrument because the calibration constants are stored on the Acquisition board,
completely separate from any acquisition data. This allows complete erasure or
removal of any secure data without affecting the oscilloscope calibration. It also
allows the oscilloscope to be calibrated in a non-secure site and then used in a
secure site with the need for recalibration.
The MDO3000 Series oscilloscopes have two USB host ports: one on the front
panel and one on the rear panel. Any USB flash devices can be removed and
stored or destroyed.
The TekSecure function does the following:
■
Replaces all waveforms in all reference memories with null sample values
■
Replaces the current front-panel setup and all stored setups with the default
setup values
■
Calculates the checksums of all reference waveform memory and setup
memory locations to verify successful completion of waveform and setup
erasure
■
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.
