Security level procedure
From the Define Menu, choose Security Level.
Unsecured: all data is viewable
When “Unsecured all data is viewable” is selected, all frequency and amplitude
information is displayed on the phase noise graph. See
.
Figure 15-10
Choosing levels of security
Implementing either of the “secured” levels described in this section is not reversible. Once the
frequency or frequency/amplitude data has been blanked, it can not be recovered. If you need a
permanent copy of the data, you can print out the graph and parameter summary before you
secure the data and store the printed data to a secured location.
An alternate method of storing classified data is to save the measurement test file (*.pnx),
including the real frequency/amplitude data onto a floppy diskette and securing the diskette. It
can then be recalled at a later data.
